Couldn't get SRB2 running through the DOOM core on BizHawk, so I did this in DOSBox-X with an early version of SRB2 from about 2002.
The following settings changed in the movie file are:
- Configuration Preset: set to (1999) IBM ThinkPad 240
- CPU Type: Intel Pentium III
- Enable Joystick 1 & 2: False
- Enable Mouse: False
To get the game running, you must put the game files into a CD image using feos' "create_iso.sh" bash script, which is located here.
