Everybody said you can't run a PSone emulator in JavaScript at full speed in the browser. It's too slow... You have the emscriptem based ones but that is not pure JavaScript and also those emulators don't seem to run at full speed. So to learn JavaScript and further my programming knowledge I decided to build a PSone emulator in JavaScript. Keep in mind it is a work in progress but at this point it is good enough to publish.
All the code resides in the docs folder so that, when pushing to GitHub, the emulator gets automatically deployed to GitHub pages. Keep in mind it is a hobby project and does not have tests nor is it very structured. When I will find the time some parts will be rewritten using TDD and more ES6 style coding.
Just go to the latest release. You can alse find the experimental WebGL2 version here. It still has some performance and transparency issues but I hope to fix those soon. Note you'll need chrome for running this emulator and read the rest of this readme before you do. On a Mac use Safari instead of chrome and give the permission to play audio on the site.
When the emulator is running and no BIOS has been loaded the eNGE logo will be pulsating with a red color. You can load the BIOS by dragging and dropping a PSX BIOS file (SCHP1001) on the emulator page. If all went well the eNGE logo stops pulsating. If you press F5 or everythime you start the emulator again it will use the previous loaded BIOS.
Same as with the BIOS drag and drop the .psx-exe file on the emulator page and it will automatically start running
Same as with the BIOS drag and drop the .bin file on the emulator page and it will automatically start running. Only raw .iso and .bin files are supported currently. The emulator will try to build it's own table of contents a.k.a track information and as such a lot of games have cd audio but it could not work in all cases.
Clicking the Qx button, toggle between Q1,Q2,Q4 and Q8 the latter being the highest quality. After doing so the border will get an redisch color indicating that you have to restart the emulator which can be done by reloading the page.
When using the keyboard:
q = L2
w = L1
e = triangle
r = R1
t = R2
s = square
d = circle
x = x
space = select
enter = start
When using the gamepad just connect it, press a button on the gamepad and the border around the gamepad/keyboardicon should become blueish and you are ready to go.
Double clicking the emulator page will stop/resume the emulator. This can be handy when the sound is really crappy.
Only one memory card is supported at this time. You can load it the same as the BIOS or CD
I have started a compatibility list. So feel free to update it.
2024-01-31: publish latest state. WebGL2 is running smoothly if your hardware supports it.
2024-02-13: SPU envelope refactors and added SPU Reverb for voices and CD-Audio.
