I modded the game using JPEXS FFDec to replace most audio files in the game with higher quality versions. These files were not replaced as I could not find which games they originally came from: music_credits fx_swish fx_startgrind fx_stab fx_speeder fx_startgrind fx_finishgrind fx_eggbombs fx_dashoff fx_count fx_break fx_bosshit2 fx_bosshit1 DefineSound 2471
