I really would like to opensource it, but I don't like how the code is right now. I'm trying to see if others such as Exophase (since he's reading...Exophase is an amazing dynarec programmer! ) will help with some rewriting of it. At that point I'll speak to Unai (who wrote the GPU and helped greatly) if he will allow the GPU to be open sourced. I think it should be a public SVN type project similar to OpenTTD imho.
If there is enough demand to raise $150, I can match it and get a C1000. $300 seems about the price I'm finding them for, and pricejapan is where it's at usually. I really want to get ZPSX updated as I think it will be truly playable (I would say fullspeed, but peoples definitions of fullspeed can be weird) at native ps1 FPS. It was close with some previous versions. Now it's obtainable with a bit of work.
I also want to bring over a new OpenTTD to the Zaurus, as well as a more "official" gpSP. Since Exophase (who is an amazing dynarec programmer btw! ;P ) wrote gpSP so well that it can support the GP2X with a dynarec, with little effort I should be able to get the ARM dynarec working on the Zaurus version if it isn't already.
Thing is, barely anyone is posting to this topic so I wonder if there's the demand for a new ZPSX, gpSP, and OpenTTD.
