Ok I uploaded a small pack of games, that I can't find anywhere.
Overdriver: I was unable to make proper disk images for this, so instead i just diskcopy'd them, hopefully, you dudes can make it boot from this.
My Today's Job: requires mouse, weird hang-gliding photography game
Cynthia V2: This is totally different then "Cynthia" in the hdd image. It's way better and has amazing SC-55 MIDI
C_Test: I don't know the proper title, but it's a very addictive "simon-says" like game. Try the "triple mode" to melt your brain
Formula X: Cool racing game that allows up to 8 players on one machine
Gradius Arcade: This is a hack to make X68k Gradius 100% arcade perfect. Uses credits and music is identical to the arcade
Larjis: Cool vertical shooter, capture enemies to use as weapons
Ahh My Princess! : Fun drop crap on monkeys game. hillarious
Logic Crush: Note same disk as Princess. Drive 0 for Logic, Drive 1 for Princess
T-94X: Cool tank war game with 8 players and nifty FMV intro
Famicom: bunch of famicom ports. the version of Super Mario is different from the one on image sites, not sure if these are freely available or not.http://nfggames.com/x68000/Uploads/undumpedx68k.rar
