It's a place for those who are interested in learning about programming, reverse engineering and experimenting with hardware/software for the console.

We have never asked for donations before but it has reached the point where the server costs are becoming too much for us.
We would like to politely ask that if you use this site that you donate any amount you can to show your support to assist with the hosting fees in order to keep PSXDEV.NET alive.

Users who donate will be rewarded with a new profile rank on their account badge ;)

Re: PSX - Sonic1 demo

This bug in the collision of the spikes near the wall also has in the original game, it happens when a collision in the air near a solid object and the scenery wall is checked.

Re: PSX - Sonic1 demo

I noticed the sprite scaling on the rings coming closer on the TV screen. Very nice effect. Managed to find a small bug in the level design too which is that you can get stuck between these spikes. I can give you some code which will detect what GPU model is running so you can enable or disable the...

Re: PSX - Sonic1 demo

Very impressive. A few bugs of course as mentioned by another user, but it looks like it's basically flawless. Original Yamaha YM2612 music from the game would be nice to have playing the audio tracks. If you wanted the newer remixes, you could have an option for it for users to select from :) :nul...

Re: PSX - Sonic1 demo

Amazing. It runs so well. I made it through the end on the SCPH-1000, shows lots of promise. Bugs: - Can't die (not even in pits) - No boss (not yet implemented) - Ring counter is weird if you loose rings Cool, I tested it and it ran 100% on my scph5501 and on a PSone, the bugs you saw are because ...
