Homebrew A new cannonball (outrun) port for the PSP

Wa59 · May 13, 2025

I just wanted to play outrun, but arcade emulators where too slow, so was the already existing PSP port, one thing led to another and now I present:

Cannonball port for the PSP with speed hacks.

This port is almost full speed with (buggy) audio!

You can get it at GitHub: Wa59/cannonball-psp/releases

Running

Copy the contents of the zipped file to ms0:/PSP/GAME;
Make sure the proper roms (revb) are located in the roms folder.

Controls

Start: Start
Select: Coins
Gas: X
Brake: []
Shift: R
Shift2: L (must change controls in menu)
View: Triangle
Menu: Circle
Turn: Dpad

Thanks

djyt, for the original project;
stacksta, for the inspiration and porting work.

Hey chief, thanks for this unexpected port, but I can't find your project on github. Can't you post the link here or attach the file directly?

Thank you for posting the link, my posts with URLs weren't working because I don't have enough posts yet.

SDL seems to be a major bugbear on the PSP when it comes to speed.

Without it the speed shouldn't be a problem, but that's of course a lot more work.

I thought so too, and even started a renderer using SceGu but the slowness was from the outrun emulation itself, the rendering was fast enough

Well go figure

As I recall the guy who was working on the port of DevilutionX (Diablo) to the PSP never got it to an acceptable frame-rate due to using SDL

Maybe there are some calculations you can simplify. Run a profiler. Doesn't have to be a completely accurate port.

Sorry to bump this, but I just tried both of the latest versions on my 1000, and both crash after selecting a music track. I'm using all of the correct Rev B ROMs too. Anyone else had better luck?

Since the OPL emulation was too slow, to improve speed I converted the music directly to wav files. Since they are fully loaded in the memory after the music selection, it crashes on PSP-1000.

Maybe I could edit the music so that it loops earlier and then it would be able to run.
