Seems like lately a lot of people are having probem with Save file for new game. I'm having the same problem myself. I've tried updating the updated software and using arm7 patch. But it's not working. Has anyone figure out how to fix the problem yet? thanks
Despite what you believe or may have been led to believe, running ROMs on flashcarts is not an exact science nor "100% guaranteed". Somethimes you will have to wait for a flashcart's firmware to be patched/updated before a ROM will start working. There is no "one fix" solution for this. It depends on when the flashcart manufacturers receive notification of something not working, figure out why, and release a patch. In order for anyone to give you an educated guess you should have provided the flashcart type, firmware version and the ROM. The community here is quite savvy, but you would also get better (and perhaps faster) results if you went to a forum dedicated specifically to your flashcart.
I have the R4 and I just downloaded the most recent software version. I loaded Digimon World Championship and My Secret World from ndsrom. Any help would be appreciated. thank you
