Its been discussed before and unfortunately it doesnt work that way, see this post for details:- http://www.assemblergames.com/forums/showthread.php?p=467079#post467079 Basically you can either have a GB/GBC cart, or a GBA cart, you cant have both in one.
The only problem with EZ Flash IV is the 2GB limitation. My set of GameBoy Advance game is around 24GB. 2.880 roms.
Say what??!?!? Ha ha. I have one, and even after factoring in SNES, Genesis, NES, etc. roms to emulate, I bought two 2GB Mini-SD's and that was plenty. They're simply aren't that many GB/GBC/GBA roms, and they are all small. You must have tons of duplicates. Actually, my beef is that to emulate, you have "build" these giant files composed of roms compiled together. Bigger they get, slower they run, and makes it a real pain to figure out what's in what. There was another GBA flash card, forget the name, that was produced after the EZFlash IV. It worked without the need to do that with the roms, but sold out quickly and the people making them stopped and never made any more.
The only other one I know is Supercard SD or something like that. But it seems it was worst them the EZ Flash IV. All my rom set came from Underground-Gamer they are a respectable library of games. Gameboy roms: 1.561 games -> 342MB Gameboy Color roms: 1.375 games -> 1.9GB Gameboy advance roms: 2.880 games -> 24GB (unzipped) I think my advance set is a no-intro one, I just unzipped them all.
For something like this use the malleable plastic tools used for opening electronic's that have shells that lock with tabs/clips
Wait, does the EZFlash IV play Game Boy and Game Boy Color games without an adapter? I just got mine last week and am loving it so far, but I haven't tried any Game Boy or Game Boy Color games, as I didn't think they would work because of the voltage difference.
Okay, thanks. I actually had looked into Goomba, but I decided to hold off to see if Igor is going to make a GBC cart (or to see if I could track down a GB Bridge). The GBA games are enough to keep me busy for now.
I hear you. I bought a couple mini-SD cards and was all into the emulation prospects, until I found out that you have to compile the roms into a single file. It's too much of a pain in the neck.
fwiw you guys may want to check out Lameboy on the DS, it's just as good as Goomba in my opinion and lets you select gb/gbc roms directly from the SD card of your cartridge. But as everyone said I would love to see a real GB/GBC Everdrive be released
Such devices already exist for GBA. The M3 Adapter exists for GBA and lets you load GBA roms from SD cards. For regular GB and GBC, a device like EverDrive would be awesome.
So there's REALLY a device for GBA that performs comparable to EverDrive? That's news to me. I was under the impression GBA carts or DS hybrid ones always cut corners. Whether it's having games run from slow RAM, limited storage space, annoyances with 32MB roms...
The only issues I know with GBA flashcarts are the facts that you need a software converter for the roms, it's not drag'n drop like the everdrive. Otherwise apart from supercard line of products who have huge compatibility problem because of slow ram everything is fine. EZ Flash IV have 16MB ram and 32MB NOR for the biggest rom and is IMO the best one.
I've had a few problems with the EZ Flash IV. I have yet to get a few games to work on it, such as Double Dragon and Mario Advance 3 and 4, and I have used ROMs from more than one source. I suppose that doesn't necessarily mean they were different dumps, though. Overall, I'm happy with it, though. Took a bit of searching on my part to find a store that is still selling them.
The "Slot-B" or GBA Cartridge M3 Player ( www.m3adapter.com ) never had any problem playing GBA games with slow ram. That was the SuperCard. The M3 has no problem playing 99% of GBA games. You load games from SD card (or CF if you get that version) and it was a reality long before the EverDrive and I'm pretty certain before the PowerPAK too. I have no idea what limited storage space or 32MB roms has to do with. 32MB is the biggest any GBA rom is going to be and the M3 has enough RAM for them. You can emulate GB/GBC on GBA and DS with Goomba and Lameboy. Emulation quality is OK but not going to be perfect. For GB/GBC if you want a Flash Cart the SmartCard 64M USB is actually very nice and pretty cheap. Around $40USD at some stores. It has things that make it a hassle to use in some respects but it does work and work well. It would be handy to have a new cart that uses SD cards and doesn't suffer some of the shortfalls of the SmartCard.
