This is a port/demake of the popular Genesis Sonic Engine (https://scratch.mit.edu/projects/74711180) made to work with Scratch 1.4 No clones, no custom blocks/run without screen refresh, and no vectors. This is the definitive sonic engine for scratch 1.4! Idk if these work but here's an sb3 to sb2 converter https://github.com/RexScratch/sb3tosb2 And an sb2 to sb converter https://kurt.blob.codes/20to14 Make sure to run at full screen to prevent lag and poor refresh. Have Fun! I made this in 5 days and I'm never touching it again.
