I think you folks must be a LOT more advanced than the average people on the net, because I searched the FAQ/Forum/etc and found no one else with this problem. Sorry if I somehow missed a sticky.

I have a Mac running 10.4.11,
Processor: Ghz Intel Core 2 Duo
RAM: 4GB 667 MHz DDR2

Firstly, what is the latest version I can install? I found a version 0.9.3, but the video and sound are full of static and lag, which really shouldn't happen with 4GB of RAM. I assume later versions have mended this issue?

Secondly, all the later versions download as .app files, which I've never even seen before. What is this "compiling" everyone is talking about? Is there a way to turn .app files into plain old .dmg files?

Not sure if this helps, but I mainly downloaded this to Kingdom Hearts 358/2 Days, because it's the only game in the series I don't have the necessary system for.

I'm sorry if these are obvious/stupid questions. I did try googling this first. This is my first Mac.

Thanks.
