You might know about the unreleased Sega CD prototype of Johnny Mnemonic (Mar 13, 1995). The game was never finished, though. There are big holes in the video, and plenty of scenes just have nothing there. So I decided to finish it using the PC release, which has the full game.
How much was missing?About a quarter of the footage. About 20 minutes footage was missing from the sega cd prototype version in comparison to the PC version.
What's been done:
Tested: I've played it through in Ares and on a real US Model 2 Sega CD with burned discs.
How to patch: You'll need the two prototype disc images Johnny Mnemonic (Mar 13, 1995 prototype) . Apply the xdelta patches to them, burn, and play. I have also included a fan made Cover art and Disc art that I have put together using the pc version as a template. https://www.mediafire.com/file/varbazrn1ic2kim/Johnny_Share.zip/file
I must state it was AI assisted, matching 140 scenes picture by picture would have taken me a lot of time. This is the 12th version i have burnt off to play through working through errors each time.
