Unirom Home
Bootdisc, Firmware, Shell for PSX
Custom Xplorer, Action replay and cheat cart firmware, bootdisc, import player, region switcher, FreePSXBoot installer, Memcard manager, kernel resident debugger...
At a glance:
You can boot Unirom from disc, a memory card, or a cheat cartridge.
Typically:
-
You burn the bootdisc and launch Unirom from it.
-
Unirom can then install itsself to memory card or cheat cart.
-
You can now boot from memory card or cheat cart instead if you want.
Installing to a cheat cart lets you boot in about a second, and dual boot Caetla.
Installing to a memory card + FreePSXBoot allows you to use models with no parallel port: PSOne, SCPH9000, etc.
How do I install it?
Installing from CD

Help, it's not booting my game!
My game is super jerky!
My laser is kinda noisy, doesn't sound healthy!
- Make sure you grab a good redump copy of the disc (not some crappy ECM'd rip from a random site)
- Try another burner (some discs prefer some burners)
- Burn it at low speed
- Use good quality discs. "Verbatim" is generally good.
- Try on another machine
- Is the disc clean?
- But like... did you really check?
Still not booting!
Okay, at a minimum I need to know:
- How are you booting the machine (cheat cart, boot CD, freePSXBoot etc)
- What model is the machine?
- What game?
- What region is the game from?
- What burner did you use?
- Is the disc clean?
- What brand of disc did you use?
- Does your PC read the disc?
- Is the machine modded?
- Is the laser making any noises?
Don't forget the info above!
Thanks
Big thanks to Nicolas Noble for putting together this mkdocs template + build scripts!
