Discussion of development of software for any "obsolete" computer or video game system. See the WSdev wiki and ObscureDev wiki for more information on certain platforms.
Looks like somebody already gone and done it.
To my understanding any PS1 game can be converted with Popstation. If i'm wrong, please forgive me. I don't own a PSP, so i don't keep up with it's capabilities and stuff.
Every time I see your project mentioned somewhere it makes me want to work on some kind of PS1 homebrew. It's a cool project to me because of the Mega Man universe and homebrew on the PS1.

Me too. It's unfortunate though that there's no way to run homebrew software on unmodded consoles. (Is there? Haven't been keeping up.)

Well, how can the PS1 tell what's "homebrew" and what's an "official" game? Isn't it just some value somewhere that's common on every officially released game that the system reads? I mean, if you got a PlayStation rom and burned it onto a CD, (would any CD work?) shouldn't it work perfectly?

There's a wobble, or modulation in the exact radial (in and out) laser position, in the lead-in of an authentic PlayStation game disc. It's similar to the pregroove wobble on recordable CDs and DVDs, and burners can't burn it. Modchips fake the wobble signal while a disc is loading.
That article is actually pretty informative. I had no idea that the data was in a spiral and not circular layers. One thing though, why haven't special burners been made for PlayStation discs? Has the wobble frequency not been figured out yet, or is there just not enough demand to make one?
Also, I'm guessing that games on disc systems don't actually tell the motor to run and everything and instead just ask for data and there's and extra CPU for spinning the disc and moving the laser and whatnot? This is off topic, but I always wondered how they have systems have a fan and how it goes on and off whenever. I'm guessing most systems have a thermometer or something and there's an extra CPU that handles the fan?

Just CDs. Subsequent optical media have been circles instead.

It's not burnable. To make a CDR they actually mold that information into the polycarbonate, not burn it into the dye in the factory.
