How do I load downloaded save files?
Solution 1:
To use a downloaded save file, you must rename the sav to have the same name as the ROM. I.E: poke.gba will load poke.sav. You must also set the cartridge save type in the emulator options to be the same as the sav file.
Solution 2:
In "My Boy!," .sav files are actually hidden in the same folders as the roms themselves. The only way that I found to show these files was to use the Android app "ASTRO File Manager." This app can go to the rom folders and see the hidden .sav files.
I would just use ASTRO to copy the .sav files into another folder, which removes whatever property makes them hidden. Then you can do whatever you want to the files and put them back into the folders they came from. Afterwards, the .sav files will always be visible and "My Boy!" will use them.
Solution 3:
Load the game in Visual Boy Advance, then Import->gameshark and load the game, then export it like export->battery file. Just find the file (.sav and .sg1 file) in the folder where your ROM is. Then transfer and rename the .sav file in your folder. I hope this will help you. :)
