Just downgrade your 3DS to 9.2, install a bootloader and custom firmware (RXTools, for example) and you're good to go. There is absolutely no need for a flashcard anymore.
where can I find a tut on downgrading and where can I find a place to download custom firmware / rxtools ?
its been a while since Ive messed with them I have a ds lite and a dsi and I cant seem to figure out what firmware. Ill figure it out and post back
I have non interest in running gba games only ds games I still intend on posting what firmware my dsi and dslite are running but havent had time to figure that out. Stay tuned.
Sorry, I was kind of in the wrong section. We're talking about DS here, not 3DS, therefore to play DS games you need a cheap R4 card. Where I come from they are sold new at flea markets for around 15 Euros. I am not sure if they can play GBA games, though.
Wow Really.. Just get the flash cart its way simple. go to www.google.com and search for gameboy advance emulator for ds flash cart
