Simple GBA Mode Switcher

***wraggster*** · January 29th, 2007, 01:47

RyanB posted a great app for GBA Homebrew on your DS, heres the news from him:

With Slot-1 DS flash carts, you sometimes want to boot a GBA cart in Slot-2. There’s probably something already out there for this, but I couldn’t find one so I made a small and simple GBA mode switcher. It uses the setting you’ve selected in your DS firmware to determine which screen to run on. This is probably the shortest DS code I’ll ever write, so source is included in this post.

M3 simply's already have an option to boot from slot 2 in the menu, I'm sure this will be useful for everyone else though

just wish someone would make a GBA launcher for MMD.

The R4's boot from Slot-2 menu option boots Slot-2 in NDS mode (like a PassMe, or like FlashMe can do), which is different from this. If you try to run the R4 menu option with a normal GBA cart in Slot-2, you'll just get two white screens.

GBA will never work on the MMD unless a full-fledged GBA emulator for the DS is created. The MMD simply cannot supply data fast enough for the GBA to accept it.

I think a gba emu would be great for ds too.
not just for mmd users.
I would like to be able to play my GBA games in DS Fullscreen!(stretched\scaled)

It would require that the GBA binaries be less than 4 MB in size, since everything would have to be loaded into the DS's RAM in order to be fast enough.
