Figured I'd chime in on this...
I saw the Sony PS1 emulator on the PSP. It's great. Ok. But DaveC might of missed one of my rants about not playing the emulators I port/write. One of the reasons I don't play (testing is different of course) psx4all, even on some of my more powerful handhelds, is because I happen not to like the PS1. So that's all I've been doing with the PSP, testing a couple of PS1 games. I don't have any interest in the PSP Homebrew scene either since they're mean to the developers.
I've actually been very busy at work. I have two new releases coming soon from that company. I'm also almost done with OpenTTD for PocketPC / GP2X. It is very much updated and is based on RC3, and has zooming and other features to make things easier to control.
As for the GBA Emulator...Exophase has stated he is still onboard with finishing the gpSP emulator for the GP2X. He was donated a GP2X and would like to honor it. So unless he decides to change his mind, I've been stepping back and giving him some time to get it done.
I was also in the process of doing the CPS2 emulator port, but luckily someone stepped in and beat me to it with a great job. It will take some polishing from what I hear, but it saved me some time.
I would like to improve upon the gpu940 project but am having some difficulties getting in contact with the author.
Also keep in mind, both gpSP and OpenTTD projects for the GP2X are open-source. Even if I were to abandon them, there is a good chance someone can pick it up where I left off. gpSP is very close to playable. I could write a simple dynarec based on Exophases framework that exists already, and most likely be done...but Exophase likes quality code and I understand it completely.
DaveC: Do you really want the GBA emulator? I ask since you've been anxious since I stopped posting about gpSP. I saw you mention my lack of posts in the Epicenter rants.
Please don't let the GP2X community fall apart...It's the most supportive community for developers to date. I truly appreciate it.
OH YEAH! If something comes up and I'm not getting posts up, just PM me. It gets my attention even if I'm working.
