PSPUAE UPDATE!!!

FOL · February 07, 2008, 09:58:08 PM

As you may have proberly noticed from the shoutbox posts. Im currently testing alot of stuff out on the 063 source (thought I had gone as far as I could with it).
Me being me, I hate giving up. So I went back over some stuff I tried before, and this time after getting a better understanding of the source.

I have now managed to get an extra 7 to 8 FPS, using max CPU and Frameskip 0. I have also been taking another look at the unreleased FAMEC source, and while I dont see the point in using it (to unstable), I have found alot of optimisations in the source that could be applied to 063 source.

So basically, I have halved the CPU cycles, which gave us the main speed increase. I have also moved the sound code from the unreleased FAMEC version, and im in the process of adding the other FAMEC blitter etc etc optimisations to the 063 source.

If people are wondering why I dont release the FAMEC version, its simple, because its not finished, its unstable and the speed it gives is the same as the current beta, thats being tested (which uses the Standard CPU core, NON FAMEC). I have now been working on the source on my own, as the other devs have vanished, they have taught me so much, just wish they had more time to work on PSPUAE.

Chilly has joined me to help, but until then, I will continue teaching myself with current source. This way you guys / gals dont have to wait for the new chilly willy version (which is obviously taking longer than originally thought). I see know point in pushing chilly as judging by his current PSP app releases, he does an awesome job and im happy to wait,

This is very encouraging news, thanks for the update FOL! Its clear as long as there is a glimmer of hope for improvements to PSPUAE - you will be first one trying to implement them! All your efforts are much apprechiated and very much looking forward to the future release!

Nicely going FOL, sorry to hear about the other devs leaving.

Horace the testmister, and all round pain in he a**e, when it comes to bugs. Has found a side effect, that seems to effect sensible software games. These games seem to not like the fact that the cpu has been speeded up. I have an idea on how to resolve this, just need to workout my idea in code terms,

.

Just incase others are having problems running any version of pspuae. I might aswell mention this, horace also ran into an odd problem, where everything was setup right, but when ever he ran pspuae the menu was all messed up. He was convinced it was something I had done to the code, so i ended up ripped my code apart, until Anemos said he was on 3.52 M33 (the FW horace was on) and it was working fine.

Horace then formatted his Memory Stick and reinstalled PSPUAE to it (so it was all freshly installed), it then ran fine. So if you have it all setup right and its still giving problems, format your ms and try again.

i'm sure it affects more than sensi games, but that was the most notable.

probably calling the chipset a lot rather than just the cpu or something.

Thank you for your job FOL and the time you spend to make happy all amiga fans!

Congratulations FOL!!!

Just to update you on what im doing. Myself and horace have identified the horrid clicking noise on sound. It seems the audio generated by pspuae is to loud, causing a clicking noise. Im working on a way to solve this.

Sweet!

This all sounds very promising. Especially the framerate increase. Cant wait to give it a go.
Good work guys, its really appreciated what you's do.

I feel a donation coming.

Bloodstar · February 17, 2008, 09:35:59 PM

...Sound? Fixed?

...I think I love you. I've been using UAE4ALL because I just couldn't stand the sound weirdness anymore. Problem is, I can't play past world 1 in Turrican 1&2 in that emu. It'll be a pretty big relief to finally be using a more stable emulator, that actually RUNS things.

FPS increase isn't too bad, either.
