Settings: Start > More > 3in1/FAS1
Rumble level - Off/Low/Medium/High
NOR Mode - Auto/Always
Backup GBA save at startup - Disabled/Enabled
Prompt before Save/Load - Disabled/Enabled
GBA Universal sleep - Disable/Enabled (L+R+Start: Sleep and Select+Start: Wake up)
The NOR mode auto setting will send any GBA ROM less than 17MB to PSRAM, while the "always" setting will flash every GBA ROM to NOR. Prompt before Save/Load will prompt the user for a "Yes/No" response before loading or saving any GBA .SAV files. This is the recommend way to use your GBA expansion cart without loss of .SAV data.
EZ-Flash 3in1
AKAIO supports native loading of GBA games into an EZ 3in1. If an EZ 3in1 is detected, it will show .GBA games. These games are launched by pressing A, then AKAIO will autopatch the game (for save type) and flash it to the NOR or PSRAM of the EZ 3in1 depending on your settings and the game's file size. The save file for the game will be loaded/saved depending your settings. The next time a GBA game is launched SRAM is overwritten as the EZ 3in1 shares an SRAM bank for saves. Make sure to back-up your save files!
NOTE: If an EZ-Flash 3in1 was purchased more recently then it may be a "3in1+" and will require AKAIO 1.4 to function fully. This includes the browser support and rumble support. GBA ROM flashing and playback has been supported on the new 3in1+ since AKAIO 1.3 Final.
