How strange, the performance should be the same as the Game Boy version. I'll look into what I can do. Thanks for the heads up. Btw are you palying on dmg mode or color?
CGB mode, using the .gbc file and not the .pocket file – I’m using a flash cart, not the GB Studio “.pocket” mode.
Note that shortly after I posted this I stopped reproducing the issue reliably. It’s like it only happens if the first level of story mode has never been beaten or something? I wish I had found a reliable repro…
