The EZFlash team sent GBAtemp an EZFlash Omega to play with and it turned up this morning.
For those unaware the Omega is EZFlash's new GBA flash cart, one aiming to be the be all and end all of GBA flash carts. Initial impressions are that it could well be so, and even if not it will see you presumably able to play 99% of the GBA library with some fancy features in a fairly solid little cart. One that retailers are listing for around 40 Euros, 50 USD or 35 GBP.
The full review will cover all the troublesome games and properly put it through its paces but for now.

Out of the box
Mother 3 fan translation. Boots just fine in RAM.
Pokemon Emerald (game with real time clock). Clean ROM boots fine, saves clock as offset clock from onboard time and savestates/real time save works in it.
Various other games were tested, including a handful of prepatched games. Fine too.
Menu. Very very nippy, minimal boot times and all on a nasty little 8 gigabyte cart of the class 2 persuasion. Odd menu ordering system (possibly date related) but you can go up and down very quickly, and left and right skip pages. Otherwise simple enough.
SD slot. Moved to a friction slot rather than spring loaded used by the microSDHC version. Easy enough to insert and remove, even with my not so dainty finger. It is not impossible that you could miss the slot but it should not fall into the case if you do.
Build quality. The plastic moulding is a bit rough around the injection marks and insides but the outside finish is fine. A micrometer was fetched for the curious. Measurements taken about the thickest edge just before it dips for the sticker inlay (it is the furthest point from any support and where most would pinch it to flex).

Device	Measurement (mm)
Omega GBA size	1.337
Omega DS lite	1.213
Original EZ4	1.013
EZ4 microSDHC	0.926
EZ4 lite deluxe	1.168
EZ2	0.882
Motogp	1.254

All that said thickness is but part of the story when it comes to plastics and sheet goods. In function the Omega most resembles an original GBA cart case in that it slides together and is retained by clips once there. Do note this if you are swapping between the stock GBA size case and the DS lite size case.
Said sliding clips and mid line screw make for a far sturdier case than the sometimes maligned EZ4 microSDHC offering (no EZFlash reform to compare here). Fit and finish is otherwise pretty good, not necessarily jewellery grade but more than suitable and accurate where it counts.
The Omega lacks the "shoulders" of an original cart, as do all the others in its immediate line (the EZ2 has them) but otherwise fits fine in a GBA SP, original DS and was a bit stiff to get into an original GBA (possibly caused by differences in the alignment grooves/insets on the outside) but still worked.

PCB wise possibly a bit light with the solder paste in some places but no cold joints or anything likely to fall off, BGA looked fine as well under a loupe.

Can you use GBA Exploader to flash games to the Omega from slot-1?

This seems better than the old 3in1.

No it has mSD card slot

 

[helltoast]

I'm aware but I remember GBA Exploader being able to flash the EZFlash IV.

And? U put roms on the mSD card

You don't seem to understand.
I remember GBA Exploader being able to use a full GBA flashcart (like the EZFlash IV) as a slot-2 GBA expansion cart, loading games off the slot-1 mSD.

I want to use GBA Exploader instead of whatever software the Omega uses.

As a rule we advised against people using GBA slot management tools with the EZ4. They had a nasty habit of semi bricking them (they would continue to work with the tools, fail to work standalone).

As such I don't know if I want to test it with my omega. If it worked with some of the homebrew it might then work with the GBA stuff but I am not sure at this point.

Why would you want to use GBA exploader anyway? The Omega loader is fine and has a whole bunch of features it does not, not to mention would probably load faster.

But why not just use the Omega software?

as far as I know the Omega doesn't support borders, does it? it's silly but I can't stand black bars.
I also have a large mSD on my slot-1 and would rather manage everything from there. preference, really.

I figured it'd semi-brick it but you might be able to reflash the firmware through Exploader. wouldn't want anyone to try it out, though.

I think the problem is whether the current version of Exploader would even recognize the Omega.
it worked with the EZ Flash IV because it was the same as the 3in1.

So Boktai 1 the US version cannot save on the ezflash Omega, but the EUR version. Interesting. Does anyone know why? Also is it possible to have full screen/ borders on any gb/gbc on goomba color?

Gb/gbc has nothing to do with the hardware its running on it will act the same no matter the gba flashcart its running on

I do have EZ-Flash 4 with me but Omega? I bet it same as 4. *Check on website about Omega then scroll down until mention about real time clock* *gasp* MAMA*Censor*ER! Shoot! I need get this flash cart so badly. I will get it someday when I have enough money. Curse you, Mr. Bills.

You do know there are patches for pokemon that make the game play pretty well, save for the berries thing, right?

Save for emerald they have been around since... about the release time of the games really and emerald standalone since 2013.

Granted I might point people at the following ones

Yeah. That what I use on my EZ-Flash 4. I have a one question that I have problem with flashcart. I do like it to play different games, but one thing I don't like it. My version is 2.050. Every time I play Metroid Zero Mission when I press L, Up, and B, it make flashcart reset. How can I get rid of flashcart reset? I do need use L, Up, and B button for same time.

Can't remember version numbers offhand and what they correspond to.
Either way it sounds like you clicked the soft reset box when patching the game.
If you are still on a kernel where you need a PC side patcher then patch the game again without that, or patch it with just the SRAM patcher or GBATA ( http://www.no-intro.org/tools.htm ) or something.
If you are on a newer kernel without it then disable the soft reset or configure it to another button combo.

I didn't use patch on computer. It patch itself when I load the rom.

Then disable the soft reset on the Keyset.cfg

How caln I do that?

Open keyset.cfg (with wordpad) and look for “soft reset” change the 1 to a 0.

I hate to say this, but after download keyset.cfg, it already 0 on it. It said default on 0.

 

[slaphappygamer]

My bad, I was thinking of ezflashIV. I believe you’re I’ll have to cleanboot the rom. The manual will have more info on that.
