personally i the interlacing options are junk. sure they make the games run faster...but why the hell would you want to play with a bunch of lines on the screen?

that is true. i think the hardwarescaling was faster and had looked a lot better.

maybe in future we do not need any kind of decreased quality. ;)

Well, one of the messages referred to the next release date as "Clobbering Time", so...

Oh sorry for the lack of updates. I worked myself sick trying to find out what is causing crashes in the cdrom handling code. I finally figured it out, and now I just need to fix it.

With the cdrom code fixed, underclocking will be easier to do and be able to be pushed much further. For instance, on a scale of 1 to 64, underclocking maxes out at 4 currently. Soon it will be able to reach the 32-64 range, which means a large speed increase whether using a dynarec or not. It also will mean the end of "fixing timings". I removed the need for one interrupt timing mess, and the only one left is this dumb cdrom code I've been dealing with the past week.

Btw, I clocked a framerate of 93+ FPS (not VSync, FPS) in Buster Bros with underclocking set at that midrange "32 out of 64". Now keep in mind the GP2X was OCed to 266 and this was in the intro of the game, not in-game. I saw it though. :)

Oh, with some of the cdrom mess sorted out, other performance enhancements can be made to that area. The timings are the first to get sorted out since whats taking up a lot of time in emulation is actually waiting for the CDROM Interrupt to sync with the reading of the ISO itself. Sounds silly and it is.

The dynarec works btw, with only a small percentage of instructions not recompiled, things are going good for it. It needs a lot of optimizations though, as it has a lot of unneeded overhead.

Once I get the CDROM mess finished, a release will be coming very soon afterwards. I know Unai wants to do some more work on the GPU as well. I think the benefits of getting this sorted out first will be worth the wait.

Oh yeah...my GP2X First Edition is dying. It sometimes takes 5 tries to boot it up even shortly after putting in new batteries. It doesn't crash, the screen fuzz's out and it makes an ugly sound. And now it's starting not to recognize the SD card. Part of the boot problem seems related to a loose power switch. It's ok though. :)

Stupid cdrom code! Back to work...
 
Does anybody know where I can get a freely downloadable image that works with this emulator? I'm not asking for ROMs - I can find those myself - but everything I try ends up with a black screen. All I need is something I can download that definitely works - even if it's just a 'hello world' type thing...

Thanks in advance...

This happens to mine as well. The way I fixed it before was taking it apart and putting it back together :p Now its happening again and I just slap it and it amazingly works ha. Thanks for the update by the way.
 
Heh Drak! I did the same thing, took my GP2X apart and put it back together when it stopped working. Then it works sometimes really well and other times not so well.

Anyways...I GOT THE BUG FIXED! FINALLY! This is an awesome bug fix, since it will allow for much better underclocking, as well as allow the dynarec to be tested. The culprit wasn't the CDROM but actually the SPU. The SPU (sound) emulation was faulty, and it might actually be related to it's timings. There was a part of the sound emulation that wasn't disabled, and that's why even with the best timings I could figure out, at times such as in FF7 after the intro, when certain sounds starts the emulator just crashed!

So this next release will not only have a dynarec (though an underperforming one possibly), but will be MUCH more stable!

Time to test the dynarec and see how it performs...Will post results as soon as I'm done testing it for a little bit!

Yay!
