GBA emulator for NDS flash carts?

[toagac]

What if we DONT switch to GBA mode... wouldn't it be possible to just have a copy of the GBA BIOS and use that bios image to play the GBA game in NDS mode, rather then switching to GBA mode to use it? If the GBA's BIOS takes up 16 KBs and then the GBA has 256 KBs of ram, that gives us 3824 KBs of RAM free to do whatever else we need to do.

Another option is to enter GBA mode via a patched copy of the BIOS that won't clear the RAM.

The ARM7 processor functions entirely differently in GBA mode than it does in DS mode, so we'd have no way of executing the GBA code unless we actually enter GBA mode. As for a "patched" BIOS, that would only help if you could replace the BIOS on the GBA's CPU itself. Even then I doubt it would help much.

YES it is possible to play gba games on the r4 ds.but it is hard.

Please excuse me for a second, I need to slam my head into the wall.

DS and DS-Lite have a slot-2 for gba games.

But does anyone have a solution for the DSi, who doesn't have the slot-2?

I don't think anyone knows but I think there was a rumor that Nintendo itself was going to release GBA games for download, for a price.

If and this is a big IF, if this is possible then possibly the DSi could be hacked to use the SD card.

Don't quote me on this.

[DanTheManMS]

Well, it's more like "if this is possible, AND IF the DSi is hacked to use the SD card, THEN possibly we can run our own GBA games on it"

The act of selling GBA games via the DSi store isn't going to get us any closer to getting the DSi hacked. I don't think that's what you meant to say, but I felt like clarifying it nonetheless.

You CAN play gba games in slot1 CAUSE Ive done it!!! I used a emulator that converts gba to nds and plays it as nds! well, graphic sucks, not all of the image is displayed, there is no sound, BUT ITS PLAYABLE!!
post the link soon!

Just google arround to see how it works you ***got. Dont say it dont work if you have no clue asshole.

You don't exactly need a slot-2 flashcart per se. You can instead get a RAM expansion cart (but not the official Nintendo one; that won't work) such as the Ewin Expansion Pak, the M3 expansion or the EZflash expansion and then use that to run GBA games from slot-1, using something like Rudolph's ExpLoader.

Otherwise (like on a DSi or something), you're basically out of luck. The DS isn't powerful enough to emulate GBA at all passably, so you need some way to run the games in GBA mode.
