Sorry for the double post, but I wanted to bump this because I want to see if I can revive this.
Basically, using this plugin, it's possible to make a (rather large) demo file of everything the GPU and SPU render. They can be played back using any plugin, including the Peter's, making it visually very accurate to the original. It's possible to record with slowdowns, and there are five save states at one's disposal. Superplay recording with ePSXe is possible!
There's ONE thing, however: the program with which these demo files can be played back (GPUplayer) does not support exporting these files to AVI. Of course, one could always use an on-screen recorder to snatch the data, but these are unreliable and often drop frames.
So is there anybody who could somehow add AVI exporting support to such a program? I don't know much about programming, and I have no idea if it's possible without the source code. Otherwise, I can see if I can contact the one who made it because he shouldn't really mind distributing the source code--the program itself is freeware.
edit: I'll upload the programs/plugins and post links here.
edit: here are the GPU/SPU plugins as well as the player for the demo files.
