I want to try the upgrades I've found on this site with my Chrono Trigger emulation, but I'm not sure how to install the Lunar IPS. I have Virtual PC for my Mac, but it says I need a system to work it... and I'm not sure what to do. Is there anything I can use to run EXE programs?
You have to use a Windows Setup CD and install a copy of the OS on a fake Virtual PC drive before you can use it to run applications.
It's slow as hell anyway. Unless you have a fast G5 and plenty of HDD space, I wouldn't recommend it for anything.
ZSNES would make alot of people happy by porting to the Mac. And it could potentially be more powerful, or at least potentially look better and have a more user-friendly interface.
But yeah, never give up. I used IPS patchers on my mac years ago. I just don't remember what I used.
None of the user interface code in ZSNES is system specific, since it has its own system-independent GUI. Anyone porting it is unlikely to rewrite those parts (it'd be hell to do), so porting it to Mac won't magically improve the user interface.
Also, hand-coded Intel assembly is very different from hand-coded PowerPC assembly. The types of optimizations you aim for are different, thus any port of ZSNES's engine would be horribly inferior to anything written from scratch with the PowerPC in mind.
So all of this "potential" you speak of is pretty damned imaginary. Even after Intel-based Macs come out, ZSNES won't be any different, better, or faster once ported to them.
