Shrink ISO for PCSX2?
#1
I ripped Metal Gear Solid 3: Subsistance disc 2 to ISO to play MG1 and MG2 (the MSX ports) on emulator.

PCSX2 works quite good for this, but I have a question; is it somehow possible to scrub out most of the disk or extract only these two games from the ISO to save on disk space? I don't think they should be a full ISO big just for those two games, right?

PS2 games are generally 3-4 GB in size, and each ISO only contains one game.

you know i never really tried this gzip compression that pcsx2 can read. until today, works pretty good cant say if there any performance issue attach to it after the initial load, seeing as i got no reason to actual compress it, but it nice to be able to read compressed isos special those that are limited in space.

Hmm if it's anything like PSP's .cso (compressed ISO) it might affect the loading times a bit. But other than that it shouldn't cause any major performance issues.

No. AFAIK, PCSX2 can't do that.

In some cases our compressed iso actually winds up being faster due to the index being built.

The .GZ compression earned about 500mb, I guess that's quite ok.
