I chose 3 different directories for gameboy , gbc and gba rom. When i start the emulator if i chose to open gb, gbc or gba rom it opens me the correct directory. But after i chose a game and play it, if i chose another type of rom it open me always the last directory open.
Another bug, if i chose to use gbc bios the emulator skips to game directly. it is a nostalgic memory to view the gbc boot.
