Someone who posted it first said that there were garbled English characters, so I sent the one I am using now. The premise is to leave enough space. This emulator does not require cracking the phone, but the maximum game can not exceed 32M
The game is placed on the disk where you put the emulator - data - others - vbag. Use a decompression tool to unzip the zip file to this folder. Use a safe manager or the like to cut the gba format to this folder.
