Hello. I found this neat thing in the uberASM code library:
LDA #$78 : STA $0DA0 ;Disable All controls.
LDA #$FF : STA $78 ;Hide Mario.
However, when I tried to use this code on a level (using uberASM of course), it only got the invisibility part; I was able to run around as I please.
Could someone help me? Thanks. :3
