New PSOne Emulator

PSPSOne: Playstation Emulator Update

When it comes to PSP homebrew, a Playstation One emulator has kind of taken on the aura of the Holy Grail. Everyone wants it, no one can find it. Playing the role of King Arthur in our story is PacManFan who has been searching for the Grail for many, many months. During this time he's made the occasional appearance on our forums to update his progress, but they have been few and far between. But today, our once and future king has returned with impressive news, and a newer alpha build of his PSPSOne Emulator.



I've decided to release another ALPHA version of the PSPSOne emulator as a demo so everyone can see how much the speed has progressed.

No BIOS is required for this demo, I'm using the internal HLE Bios built into the emulator. This is the same Paradox demo I released last year, except this runs much faster.

Some techinical info:

-This version is running with the interpreter CPU core, not the recompiler.
-This is running with full 256x256 textures (I can get better speed with 64x64 or 128x128 textures)
-No sound
-Partial debug loggin enabled
-partially optimized build

I'll add a fps counter to all future versions so you can see speeds for yourself. Remember that this Paradox demo was designed to test the very limits of the Playstation.

Just so there is no misunderstanding, This ALPHA demo is hardwired to play a single psx demo file that I have provided, It will NOT run a game in it's current state. I plan to release a playable BETA version very soon that has a GUI, mapped controls, and the ability to select and load psx/bin/bin.gz files.

Also, would someone with a 2.0 check to see if it works?

Please remember to donate!

From psp updates... i dont know about u but im trying it

i will try it later on this afternoon or evening and will give u guys updates. But i need some ps1 roms, hehe. Hope its much better than the original ps1 emu.

yeah i have to try this and hope it works too!

did anyone try it yet???

well the thing that kind of swayed me away to try this alpha version was that it doesn't load roms yet, just the one that is provided, but i still will try it out soon!

EDIT - I tried it out and all it is is the beginning of the ps1 emu - it runs ALOT faster than the last one...

did u download something i didnt? cause mine brought me to a black screen that is unfun to be at

yeah i downloaded it, but it just takes me to a movie in ps1 quality, and shows how much faster it goes than the last version, and it does go pretty fast.. why do you want a different link?
