Because i could not find a freeplay rom version for the Atari SpaceRider pinball machine and hate to toss dimes into the machine or add some pushbutton to accomplish this i felt the urge to take a chance and began disassembling the romcode using the fantastic tool IDA (InterActive Disassembler) .
Although not complete yet, i managed to disassemble and comment most of the code. With the disassembly at hand it was very easy to alter the code and as such i do have a freeplay version for the Atari Spacerider now. Below you”ll find the github with the disassembled code.
