My DSi has gotten really old and worn down to the point where the volume no longer works. I'm looking to buy a replacement but the problem is that the only flashcart I have is the IEDGE meaning the DSi firmware can't be greater than 1.4.2E. I've been looking on ebay but the only way I can find out the firmware is by having to contact the seller. Anyone know what I can do? Or should cut my losses and by a new flashcart as well?
