Appears iQue DS games were intentional region locked after all. As opposed to the suggestion of compatibility issues. 3DS not enforcing that check was among potential clues (I myself tried them on Supercard DStwo). Furthermore its current bypass involves one bit. Vastly simpler than any of us would've expected. :cool-new: Hex address 0x1D according to http://tcrf.net/Nintendo_DS. I've saved you some time with an xdelta patch archive. http://www.mediafire.com/?udzc894tknsrynf
Congrats. But it's only compatible with dumped roms? (Or do the original carts work a US 3DS for instance?)
The only reason id care for this would be if there was a game exclusive in Japan for a series i love, but yet, there is not. :excitement:
