I am a beginner at Assembly. I am trying to make a DDR like game. Can someone please help me call the audio (SONG1 PROC) properly in the play window alongside with the graphics? The graphics are messed up whenever I try to call the audio. I cannot post the code since it's 1000+ lines. I'm not allowed to post asm file either so I posted it as txt. I run it with MASM. Thank you.
