This is an awesome game but the download does not seem to be playable. It contains 3-4 versions of the game all with their own problems.
The one marked [cr CSL] appears to work fine at first, but past the second level when it's supposed to pick up disk 2 it struggles a bit and throws you back to title screen. I tried to load the disk manually as the cracktro suggests and it turned out to be a disk for Defender 2 not Zarathrusta.
The other marked [cr CSL][t +4 Rastan - Felix] picks up the second disk fine, but for some reason any key on the keyboard activates ship thrust. I guess it's a weird hack that's supposed to make the game easier, but IMO it ruins it.
Others makred [cr SKR] I only tried one pair of, and it didn't go past the title screen, and I don't have much hope of any others working well as the two versions for disk 2 in that group are makred as having corrupt files.
Tested on RetroArch androud with PUAE core.

Here is a download that's playable at least to level 3, which I'm not good enough to beat apparently.

It's a single hard drive image instead of two disks.
