Homebrew [PSA] The lastest mGBA nightly runs pretty fast.

[Searinox]

Reminder that the latest mGBA has added support for colorizing classic Gameboy games. If you refuse to use a GBC BIOS because it overrides Pokemon Red/Blue et. al. with shitty colors instead of their SGB colors, you're also stuck with grayscale Gameboy unless you use this feature. Unfortunately there is no interface for configuring these in the 3DS port so you will have to add the colors to the config manually yourself.

In the [ports.3ds] section of the config.ini file, create a series of variable entries called gb.pal[#]= with the number in the brackets ranging from 0 to 11. These numbers are, in order, palette colors to be applied for the Gameboy. The values are in groups of 4: 0-3 cover the background, 4-7 are for sprites and 8 to 11 are for a secondary set of sprites. Each set is ordered from brightest to darkest color. The numeric value following the equals sign is given in decimal format and is a 24-bit integer representation of the classic RGB color format, meaning that you can figure out your choice colors in hex RRGGBB and then convert to decimal.

Here is a sample coloring:

gb.pal[0]=16777142
gb.pal[1]=7265390
gb.pal[2]=3325490
gb.pal[3]=9216
gb.pal[4]=16769762
gb.pal[5]=14446190
gb.pal[6]=12464690
gb.pal[7]=3276800
gb.pal[8]=14869247
gb.pal[9]=7237340
gb.pal[10]=2631870
gb.pal[11]=50

Fans of the Pokemon - Liquid Crystal romhack, the RTC has been fixed in the latest nightly. See issue #1134.

Unless you're some sort of nuzlocke masochist... With the clock now working, this game running speedily (at least on new 3DS series), and that it saves of course, rejoice having the addition of save state. Yay!

Where should the config.ini file for mGBA go in the 3DS SD card?

Also, do you happen to have the palette coloring that would look like the classic DMG green that the VC emulator uses? Or at least the green palette available on a SGB?

I was checking out the current beta of mGBA and was really impressed with the sound accuracy. The music of level 1 of Trip World, a very advanced track, sounds pretty much spot on (on other emus for 3DS and DS it never sounded correct). Looking forward to the next stable release.
With the ability to use the top screen with a pixel grid look (currently only the bottom screen seems to do this, the top screen perhaps needs to use the 3D to do so like the VC emulator) and also the ability to change coloring of GB games through the menu this would be my go-to for all GB/GBC gaming.

The file is located in \MGBA\config.ini on your SD card. Unfortunately I do not have that palette. I made this one up by myself lol.

@Searinox

Thanks for the info. And that's alright. When this very promising emulator gets updated I'll look into making my own GB palette (or hopefully they add palette's as a feature like Gambatte).

Another feature I really hope is implemented is color correction for GBC games. Now it does the same saturated colors of a backlit-GBA/NDS. It's surprising that GBC color correction is not more standard, even the Wii port of madnafen does it by default! It's also interesting that Nintendo corrected colors for some VC GBC titles (like Link's Awakening DX) but not others (the Capcom Zelda games).

mGBA 0.7.0

Jan 26, 2019 – written by endrift

After an extended incubation period mGBA 0.7.0 is now available. This is a major feature release. It features a brand new Nintendo Switch port, vastly improved Game Boy support, dozens of bugfixes and accuracy improvements, and more debugging features. A full list of changes follows after the cut.

With the next stable beeing released, I will begin to update the mGBA wiki for N3DS/N2DS later today.

https://wiki.gbatemp.net/wiki/MGBA

Edit: I´m getting the same issues as this guy on github. https://github.com/mgba-emu/mgba/issues/1281
The testing will be on hold until a solution is found.

The the next version (0.8.0) is supposed to have an arm dynamic recompiler. So it should run full speed. (Maybe even on the o3ds.) So that should be cool. We're currently using an interpreter core.

Hmm, I just tried it and everything is working fine. GBA loads and plays normally and GB works fine.

 

[Deleted User]

I tested a couple games with the latest build (0.7.1) released for the 3DS.
My N3DS no longer crashes, I will soon begin to update the wiki.

 

[Pickle_Rick]

Kinda necro but I just tried the latest nightly and Yoshi's Island is full speed.

Try with Golden Sun 2 or Mother 3, those are the heaviest games possible for the system.
Those and maybe the Dooms or any of the like.

It still lags in monkey ball but it's like 40-55 fps now. Also, in games that run full speed the audio is much better now.

 

[AkitoUF]

Or just use the VC.

If you don't have anything relevant to post. Don't.

 

[Rahkeesh]

FF Tactics and Sonic Advance 2 still dip to around 55 but the audio is more tolerable in that state. Mario Kart also seems to get up to 50ish. Aria of Sorrow also seems more stable at 60 than I recall. So yeah, some real if minor improvements.

Edit: LttP / Minish Cap also running very smooth now, basically fullspeed!

The next stable has been released.
mGBA 0.7.2 is a bugfix release.

 

[pasc]

What about Golden Sun 2?
That's my defacto ROM to test mGBA on any system.
It always used to stutter in the 3DS port, how is it with the latest nightly?

You should change that test to "Payback"

 

[cimerio]

for me, it was a deception. the games are slow and the sound fails. maybe my console doesn't offer sufficient requirements (2DS) for a good emulation.
I tried Alladin, Castlevania and Final Fight, everyone with poor results.

injection is not a option for me. I can't put 70 games on home screen.

70 is nothing so inject away
