I just got the ezflash 3in1 and I used GBA ExpLoader v0.58, which I probably shouldn't have used for my R4... and all it did was show GBA intro screen and stopped. I used both of the save options and it just stopped working. Whenever I turn on my DS it just shows a white screen if the flash cart is inserted, otherwise it works fine. Could any of you help? :S
you probably loaded a game into PSRAM mode and not NOR mode. either that or your trying to load a 32mb game into PSRAM.
Also some games require you to reboot the NDS when its flashed to NOR the first time. This is easy to see as it will show the GBA logo and hang there. Reboot and run and it should be fine Greetz, Vistabuser.
