Eighteen years. That's how long it's been since the launch of the Game Boy Advance. It continued the legacy of Nintendo's massively popular Game Boy line, and to many, is considered the very best portable game system to ever exist. Not only did it feature an incredibly strong software library, but the GBA also had a comfortable form factor that later revisions to the line (SP, Micro) wouldn't be able to hold a candle to. Being a system from the early-2000s, though, it had a few things that held it back from true perfection; backlit screens were still an anomaly at the time, so if you wanted to play anywhere that didn't have bright lighting, you'd basically be playing blindly. Not only that, but the sound quality on the GBA was less than impressive, and the handheld was powered by AA batteries, which might not be a problem for everyone, but can still feel like an annoyance to scrounge for, if you don't keep them stocked around the house anymore. 

Why exactly are we talking about the GBA, you ask? Well, what if I told you that there was a way to remove the biggest flaws from the Game Boy Advance, without resorting to emulation on another device, or having to spend time playing Operation with various parts of your system? The answer to that is in the form of this perfected GBA, made by JayBoyModz

GBA mods have been around ever since the advent of the Afterburner, when modders began opening up their systems to install a frontlight to make the screen visible in low lighting. It was fine for its time, but the Afterburner wasn't perfect, as it didn't light up the entirety of the LCD, and it could cause weird distortions when viewed from a certain angle. Later, after the AGS 100 and 101 GBA SPs were introduced, people began transplanting those screens into a system that wouldn't make users' hands cramp up after playing for extended periods. While those that have experience tinkering with hardware might not be daunted by the idea of cracking a GBA open, there's a lot that goes into the process: you need to acquire a backlit screen, a ribbon cable, a screwdriver capable of opening the GBA, a soldering gun, and of course, the ability to solder. Not to mention that you'll need to keep in mind that some models of the system don't have the right pin connectors to fit the mod out of the box. 

So, if you're like me, and feel daunted by the process of going through all that work, yet you don't want to give up the dream of having a well-lit Game Boy Advance, Etsy seller JayBoyModz happens to sell tricked-out GBA systems, with all the trappings and trimmings that you could ever ask for. Not only does he make backlit GBAs, but he also can add other upgrades such as a rechargeable battery, an audio amp along with a newer, better speaker, a brightness controller, a glass screen lens, USB-C charging, a light-bleed protector, a voltage regulator, custom buttons and shells, and last but not least, an accelerator, which can let you overclock the GBA. That's a lot of stuff to put in one small handheld! GBAtemp reached out to the seller to ask if we could demo one of his systems to do a review, and I got the chance to play around with the best custom Game Boy Advance he could offer.

Softly packed in a pile of tissue paper and styrofoam peanuts was the little GBA, fully outfitted in a light blue case shell with orange buttons that were made to represent Tempy! It looks absolutely fantastic; the shell is vaguely translucent as well as the buttons and orange trim. The casing is cut well, meaning everything fits together nicely, with the plastic pieces all sitting flush with each other. There was only one thing that stood out to me, which was the battery cover, as it happened to push ever-so-slightly out against the GBA itself. It's hardly noticeable, and I only came across this due to the fact I was actively trying to find the slightest of imperfections with the unit. Considering that there's a lot of mods going on under the hood, a minor rise in the battery cover is more than worth the tradeoff. 

Upon flipping the power switch, I was greeted by a vibrant glow, which was far brighter than even what my AGS 101 SP could output. Thanks to the digital brightness control, I could cycle between five different lighting levels by pressing Select + L/R. I preferred using the second-brightest setting, as it was plenty bright. The brightest setting itself is exceptionally bright, but in some games, it washes the color out just a slight tad. 

In all my years of gaming, I've played GBA titles a variety of ways, and though emulation on the Switch, or the Vita, or even the 3DS is serviceable, there's something to be said for experiencing games on their original hardware, the way they were meant to be enjoyed. The original GBA is so nice to hold; there's no heavy second screen like the DS, nor is it too small like the SP is, and with a backlight like this, you'll never have to worry about not being able to see your screen. There weren't any issues with light-bleed either, and the only time I could see the outline of the backlight was when I tilted the GBA at an unreasonable angle. When playing in even the most pitch-black darkness, you're never going to encounter any excess light spilling out from the sides beneath the screen.

Since this custom GBA runs off an internal battery pack, you won't have to worry about your AA batteries getting decimated by using the screen on max brightness. In fact, the newer screen is actually more power-efficient than the original screen that came with the GBA, so regardless, you'll get more mileage out of each charge/battery than you would on a regular GBA. When you want to charge it, all you have to do is grab the charging cable, which is included in the box, and thanks to the indomitable power of magnets, it snaps right on and begins to charge. With the 1600 mAh battery upgrade, you're looking at around 15 hours (though I averaged a bit longer than that) of playtime before you need to charge it back up again. If you prefer AA's, you can opt to keep them in the build, although, it's hard to resist wanting the magical magnetic charger! 

For those who have tried enjoying tunes on the GBA, you might remember how tragically quiet the audio could be, sounding fairly muffled when played through the handheld's low-quality speaker. Luckily, the speaker and amp mod manage to make the GBA play loud and proud; almost so loud, that I'm questioning if people will be able to hear the GBA blast its audio all the way across town! 

Earlier in the review, I mentioned that there was an Accelerator chip. If you've never heard of one of those before, it's a little chip that once soldered to the GBA's board, allows you to overclock your system. There's three options to choose from: 1.5x, 0.85x, or 1.75x speed, which can be incredibly useful if you're replaying an old JRPG and want to skip through text, or if you want to mess around and see how wildly different it is to play platformers like Super Mario World or Sonic Advance at nearly double speed. It's a fun little feature use every now and again, and if you still happen to have an old flashcart, you can run some homebrew on the GBA for old time's sake, and get some extra CPU cycles when it comes to intensive homebrew. 

 

All that considered, I absolutely love this custom GBA; JayBoyModz did a fantastic job on all fronts when building the system. The plastic housing both looks and feels nice, and the buttons are clicky and don't stick, unlike how cheaper materials tend to do so. Careful work went into ensuring the backlighting didn't spread outside the screen, and the glass screen lens really makes looking at the GBA's 32-bit sprites a real treat. If you ever want to have a Game Boy Advance that is not only amazing to play games on, but can also be a stunning showpiece on your shelf, I would not hesitate to recommend this seller.

Overall

With all the little mods jam-packed into this system, this is undoubtedly the peak GBA experience that one can have. The prices can appear to be a little high, but when you consider that you're paying for all the parts and labor while not having to risk any problems in soldering it or fitting everything together, the cost feels justified.
I wonder what lcd they used to replace the original screen. Would love to know. Most of the ones out there are terrible, trashy ones.

I've done a few of these mods, but seems like this person knows what they're doing. I'm not sure I'd pay 200 bucks for one, but for all the work involved, probably a pretty reasonable price. I'm just a cheapskate.
 
$200? What....? Why?
To play GBA games comfortably without buying an all-around superior SP model! c:

But joking aside, it's a hobbyist project made by one person that requires complicated handwork for each unit. Selling that for a lesser price would be just kinda unpractical, considering the amount of work.
 
Does the $200 include a glass screen? There's an upgrade for one, so I assume no? Found some cheaper ones that offer a tad bit more. So, I don't see myself justifying that price point.

$200 is expensive i agree, when i modded mine myself it didn't cost that much at all.
but when you pay someone to do something, they charge extra.
let's say you get an old gba for $35
the backlit screen, maybe $40-70, recently the prices have been going up which is annoying
the new (fake) shell if you want one, $10
custom buttons, $5
rechargable battery mod $20-30
it adds up.
if you just want a backlit gba though, it's not expensive to do yourself

the glass screen is only like $5-10, not a big price.

i saw a usb c charging mod for the micro. it's possible if your soldering skills are good enough :)

many people agree that the chinese aftermarket backlit screens (as in, not the official ones taken from backlit SPs, that can also be used) have better picture quality and power consumption. i'm certainly happy with mine.

there's a famous guy (in the gameboy hardware hacking scene) who is making a ds lite screen mod for the gba, so it will be easy and cheap to put a ds lite screen in the ba to backlight it :) cheaper than using SP screens/chinese versions of them

I must have bad luck. I bought two from different places rated fairly highly and they both were atrocious screens. If you've got any recommendations, I'd love to replace mine with some actual good ones :P

I'm wondering the quality of the screen they used compared to other easily obtainable ones.

This is one of humanity's greatest inventions thus far !
Jokes aside, The CPU overclocking could truly help some GBA homebrew namely some few emulators the GBA buried and lost in obscurity.
Whether this emulator would attain any reasonable frame rates than is arguable if unlikely. Lol who knew there were even such a thing as a "SNES emulator for the GBA"
http://www.pocketsnes.net/
On the other hand pocketNes could perform much better seeing as it's merely a NES emulator and NES emulation isn't as demanding.


Nice review by the way.
 
SP? Superior? maybe for the screen, out of the factory... but for ergonomics, the original GBA was much better to handle.

Not to mention I never had shoulder buttons failing or getting squishy with the original GBA, whereas it's a constant problem with the SP and basically everything up to the 3DS family of handheld systems.

Yes all the builds do include a new Glass screen lens with the original GBA Logo. The option for the add on is for someone who may want a custom design printed onto the glass screen

$35 for an old GBA is way too much. I see them at my local swap meet for anywhere from $5 to $20 all the time.

And not one bit about the history of the 101 mod, which started right here on this website, the threads are still up on the respective forums. 200 USD for what anyone without two left hands can do himself is a bit steep. It's a 101 mod, which is on its way out, with the displays becoming pricier because they're not made anymore and pretty decent replacements are on their way in. The funnyplaying mod is pretty interesting, but has a bit of screen tearing and I think most of us are excited for BennVenn's NDS display mod (NDS lower screen display instead of a GBA one).

All info that should've been in a well researched review. Seriously, are GBATemp reviewers not expected to bring an ounce of research into these reviews? You're herding people into buying 200 USD systems which aren't worth that money anymore with better options on the way. Recommending that mod would've been okay five years ago, but not in 2019.

I love the Game Boy Advance, but even I can't justify paying two hundred dollars for one. Pity. Luckily, I have several Game Boy Advance systems, including the SP Mark 2 and the Mini. I do like the form factor of the classic GBA, but really, I'm good.

2 bills? Screw that, would certainly get one if I was less poor though. Got an ags101 screen on the side for the last year i’ve been too lazy to install
 
Afaik BennVenn is working on a new replacement GBA screen for this that's gonna be around $20-$35. What im gonna do is get a cheap junk spice orange GBA from ebay, one of those nyko Wii battery paks and wait for the BennVenn screen to come out. Hopefully I can get it for less than $100 even with shipping from Australia :P

Oh, okay. Thank you for the clarification. After reading and comparing a bit more, this isn't as strange as I thought.
 
The price is on the first look really expensive... but when you try to get yourself the components and hardware from zero and I mean you don't have any Gameboy advance you will really fast reach the 150 Euros here in germany. Usually you only get the "china" screens on ebay for like 70 Euro and 2 Months shipping time... and some of them have ghosting. To get a real 101 screen here in Germany is kinda impossible or everyone wants about 150 euro only for an 101 GBA SP... I'ts crazy! I tried to mod my own GBA gut gave it up when I was looking for "cheap" screens. My opinion under 150 Euro its really hard to build an very good GBA mod. So the price of 180 $ seems fair.

Yes, you are right, and i've seen other modders selling this for 400 dollars. As for the aftermarket screens, in my experience it's a bit of a gamble, i have an aftermarket one and it's just as good as the one on the 101 SP as far i can tell. Many fail to regulate the voltage when modding the 101 screen which makes the screen look terrible.

I mean, it's cool and everything but I ain't paying $200 if it doesn't come with box and inserts. lul
 
This is pretty cool!

So, with Castlevania on everyone's minds with Bloodstained ROTN, who here played Castlevania Circle of the Moon on the OG GBA back in the day before the SP!? Because a member of that squad is reporting in here!
 
Wasn’t there a mod coming out to use the ds screen instead of a 101? Wonder happened to that.

Also, I might pay 200 for this. The gba is tight to work in and requires some fuss to close it properly. The 5 level brightness is very nice. My adapter was 40-50 USD. Spring for that option if you can. Looks like a great unit. I’m digging the tempyness.
 
P
Mhmmm. Nice. So good I had to get one too.

Now where is my *not overpriced* gba hdmi mod ?


The only worry I have that one day GBAs around the world will break down *sigh*
(Components only last this long.. wish Nintendo would reveal all GBA info, code etc to the public, for a perfect replica to be made... [then I could put all the info into a safe 10m down under])

A right, that was the day hell froze over (not even the DS can emulate SNES all that well...). Impressive stuff.

Then again, maybe the EZ Omegas vast Ram could also help in aiding this

Here are my beloved ones ;)

That Supercard.. I've only heard bad things about it... and it is super cheap at ebay... Opinion ?

Hmm. The best one right in the middle :D
 
This is absolutely amazing! Why doesn't Nintendo endorse this? This is a very good remodeling of an old system, and checking out his other products, it looks like these things should be licensed by Nintendo!
 
Look very great! That person who made modded GBA with back light screen and recharge battery in back of system. Person did good job work. I love modded GBA design.

About battery capacity is 1600 mAh is small. Should must upgrade to big capacity over 1600 mAH would be much better. Upgrade to 2550 mAH and above would be overkill and best for more longer hours play time.

I still have my old GBA and GBA SP. Both still working so far. I still have Everdrive GBA X5 flash cart for my GBA/GBA SP and Nintendo DS, 2 NDS Lite to use anytime. :)

I used AA batteries (alkaline) often with my GBA. When I stop play, I forget to take AA batteries out, but leak little of acid in my GBA battery hold area. Lucky not damaged to board, acid don't touch board. Thank god. I cleaned to remove acid from battery hold in back of GBA. I hate alkaline batteries due to leak often times!

I no longer buy alkaline AA batteries anymore. Because alkaline batteries are always leak all of times in random months or years. I stop buy to cease support to alkaline batteries. Reason why all battery companies should must end support or ditch alkaline batteries to replace to NiMH or Lithium or Sodium batteries (new world's first solid state - sodium ion batteries will be start to produce in year 2020 and after). I stick with NiMH rechargeable batteries for many years but never leaked for many years due to high quality made and big improve over old technology of alkaline batteries.

I have many NiMH rechargeable batteries right now. About 58 AA batteries are NiMH and 16 AAA batteries NiMH. I love NiMH batteries so much and top quality brands than lousy alkaline batteries. I have most of Duracell AA batteries are made in Japan, few are made in China (2000 mAH, 2450 mAH, 2550 mAH and 2650 mAH). I have 24 AA batteries name are Fujitsu 2550 mAH High capacity and 8 AAA batteries name are Fujitsu 900 mAH High capacity made in Japan, both are black color, not white color print on them. Longer battery life over old alkaline batteries.

I have about over 10 years old 4 AA 2000 mAH and 4 AAA 800 mAH Rayovac rechargeable batteries NiMH are made in China. 4 AA Rayovac batteries don't leak yet, but 4 AAA batteries are leaked on top. Know quality problems due to made in China. I just wash my older 4 AAA Rayovac NiMH with warm water and soap then dry them and can be reuse again. I have voltage meter device to check and still show 1.2 voltage. I put them in recharge device to go up to 1.4 voltage and work just fine. No dead NiMH batteries so far. :)

Good news in year 2020! Some battery companies will going to start produce first solid state - sodium ion batteries in year 2020! I will look forward in there and will buy some for my need. Sodium ion batteries are successor to Lithium Ion batteries. More longer capacity life and can rechargeable over 2,000 times are big improve over Lithium and other old rechargeable batteries like NiMH, NiCd, etc.

Cheers :)
