Well, I for one ordered me a Passme dongle, so that I can use my GBA flash cart for NDS development

. But I’m not saying I’m going to do this!
Funny thing, I never got me a separate flash programmer for the GBA, I’ve been using my MBV2 cable instead. Also, I’ve got an older model flash cart which is larger than regular flash carts. So when I want to do something with my NDS, I first got to connect my GBA to my PC with the MBV2 and use that to program the flash cart, then put the flash cart in the NDS’s GBA slot and the dongle in the NDS slot, sticking out on both sides ^_^.
The upside is that the setup is cheap, and I only need to get a Passme thing which isn’t expensive either ^_^.
