AFAIK its the same disks as of the C64, you just BOOT the C128 with the 1st disk into the drive... I think the game uses the C64 mode of the C128
I have to do some tests now, as I have a version of U5, (on D64s) that runs with SOUND on the initial screen under VICE 128....
[Update]
The version that I have works OK under the C128, tested with the uIEC/SD too!
