My hardware is: NDS lite (original firmware), AceKard 2i (using AKAIO 1.5 with latest loader), EZ-Flash 3in1 (2nd board according to Wiki OR EZ5C10 ), MicroSDHC Sandisk 4GB. My problem is: Scenario: New GBA ROM to load; I run the Rudolph's GBA ExpLoader v0.58b then select my game, a pop-up comes up to select the slot to use obviously I press 'B' since it's a new game. Everything good, analyzing and writing to RAM comes up, and presto! the game can be loaded. Then after turn the system off and on again I run the Rudolph's GBA ExpLoader, then a message comes up asking me to select the slot to save the battery... THEN it hangs up! I have to reboot again the system to get it work again, but the SAV did create since it does not ask me for the slot. Any suggestion? anyone with similar problem? NOTE: this happens to me again with the Rudolph's GBA Backup Tool at the point where I select to get the battery to .sav file, it hangs up.
