gpSP is a well known Gameboy Advance emulator available for a bunch of systems. It was initially written by Exophase.

Release notes:

I head from the users that the game_config.txt from the past works better than the one packaged with 0.7.2. Some say that the Pokemon Fire Red works with this game_config, while it doesn’t work with the one packages in 0.7.2. For me it seems to be working with both game_configs, so I decided to make a new package for you. Does this one work better, do we have better game compatibility, or do you prefer the one packaged with the older 0.7.2? You can reply in the comments section.

This version supports only Symbian^3 phones with Symbian Belle refresh installed (N8, E7 etc.). The old Symbian Anna users should still use the older gpSP 0.7. The S60 5th edition users should use the gpsp 0.6.5 for S60 5th edition
