1) The Linux version is for x86. I'll look into doing versions for other CPUs, but I can't promise this.
Ok, as long as you look into it. Hopefully it won't be that big a project ;-)
2) There will be at least one more update for the Amiga version, although I can't promise that all the features from the PC version will be included. (For example, the 16-bit renderer wouldn't work on AGA.)
Who the feck cares what works on AGA anyway?
I'll be playing things on my A1 under AOS4 WELL before you get that updated version out, and allready I am using a Voodoo3 in my A1200. Why even mention AGA anymore? ;-)
Anyway, good luck to you, I'm considering whether Payback would look good on my office computer running Linux, but I'm pretty certain it would. :-P
