ever wanted to experience Sonic Chaos v0.20, but your Master System model crashes past the title screen? maybe you don't have a Master System, but have an emulator, but it also emulates the crashing behaviour? well, you're in luck! this hack only replaces the faulty `out` instructions that caused the crashes with harmless `nop` instructions that don't do anything. now you can play through an early version of Sonic Chaos unchanged, except for the annoying parts you can't get past!
I made a fix for this not long after the prototype was released. Though I never fixed the issue where it would crash after pressing start on the title card sequence... Good effort though, I always love seeing others hack the 8-bit games and to see someone make a hack without a disassembly is awesome! https://forums.sonicretro.org/index.php?threads/sonic-month-2019-sonic-chaos.38903/page-4
I don't think I saw that one, but it might have already been solved by my other modifications. I can't check at the moment. there was also one crash that happened at the tail-end of the title card sequence, if you didn't press anything, but now it's been fixed.
