Hi !! I don't understand : roms GG (*.gg) work well but roms SMS (*.sms) don't work. Why ? Thanks a lot for your response.
For example, I tried rom "Ghouls'n Ghosts (USA, Europe).sms" , counting is done but then nothing happens ...
Are you using a Japanese Game Gear by chance? Unlikely but never know. (that's easy to identify, Streets of Rage will become Bare Knuckle, much like the Genesis version does in JPN mode) I haven't heard of Everdrive GG being tested on them.
