The PC version of the game was developed by Probe, and published by Acclaim in 1997. Given it's on PC, this version is accurate to the arcade. My understanding is the initial release had some gameplay issues, but a patch was later released that apparently fixed everything.

This version appears to have been released in the USA and Europe. Induk Hwang sent me an e-mail showing pictures of a Korean version he owns, so it got released in Korea too. It's not that pricey, but complete copies on eBay tend to go for around $50. However getting it to work on modern PCs may be an issue.

This version has a cheat menu that lets you play as both of the bosses, among other things.
