I read some of the stickies that would be related to my question, but i couldn't find an answer. Simply can my old R4 (original one) work on my DSi that i just got? I have a dslite and it works fine on that (currently on the wood r4 firmware), but when i try it on the DSi; it doesn't decect the flash cart at all. If it can work with the DSi, please help show me where to get it working. If it doesn't work, which flash cart (cheap) should i purchase that would be compatible?
