The prototype build 1207 of Knuckles' Chaotix, dated Dec 07, 1994, 07.15. It was released by drx on February 23, 2008.
Notes
- Due to an interpolation code bug in this build's version of the PWM driver, corrupt PWM samples play in lesser accurate emulators when music is heard. This can be patched by doing the following in a hex editor (fix thanks to ValleyBell):
- search for D013 4420 4620
- replace 2041 2061 with 2061 2061
- 6 bytes later, replace 2051 2071 with 2071 2071
- fix the checksum by adding $0040 to it.
- The header still contains the name "Knuckles' Ringstar", while the game is called "Chaotix" everywhere else. This is an early working title for "Knuckles' Chaotix".
