The release of Devolution for Wii got me thinking about this. Currently, playing GBA dumps on the DS requires a DSTwo card for emulation. But we already know that the DS can play GBA games natively using its secondary, ARM7 processor. So, my theory is that DS homebrew could run a GBA game natively on the second processor. I asked tueidj about how Devolution works and if it's difficult to do. He responded with; I'm none of those things (nor an ARM expert, which would be a requirement with the DS/GBA), unfortunately, but I do know that the GBA had only 256KB RAM vs the DS's 4MB (less than 7%). If it could be done, various benefits could be possible, such as: Link via WiFi (perhaps even link to Devolution for GC games that support it, if tueidj was interested in collaborating) and the Internet. Using the DS's sleep mode Return GBA support to DSi/3DS with any homebrew supporting card. Cheats, RTS, etc. Are there any experts around here that think this would be possible, or know anyone who might be able to do it?
