Mod-free booting

Once unirom has booted (from memcard or via flash cart), it will unlock the drive via nocash unlock* meaning you can play imports and stuff without needing to swap discs. Except on Japanese units. For those you can use a modchip, xStation, etc or just stop the disc as described below:

  • boot with a black disc in
  • go to the boot menu and hit "stop disc"
  • swap discs
  • don't look at the fucking laser ( it'll be deactivated, but incase it isn't for whatever reason, don't fucking look at it)
  • put your other disc in and boot as normal.

It's not working!

Someone's probably solved it: Troubleshooting

note*: some nicolases don't like the term "nocash unlock"

PAL/NTSC switch / region override

Allows you to force the video mode of a game to PAL or NTSC.

  • PAL->NTSC will be the slightly higher PAL resolution with the slightly higher NTSC framerate.
  • NTSC-PAL will be the slightly lower NTSC resolution with the slightly lower PAL framerate.

There's a clear winner there.

Help! It's black and white!

Some hardware just can't handle the slightly off-spec video output from one machine doing the other's output.
You can use a better scaler, DFO mod, etc or just enjoy it like an old black n white movie.

Note: This feature is unlikely to work with homebrew that doesn't use the official PSYQ SDK.

File Browser

The file browser lets you poke around for files on the CD.
Valid file types are detected by their headers.

ROMS

Flash ROMs to cart exactly like any other method.

Memcard Images

Any valid (raw) memory card dump can be written to mem cards

.EXE

Load and Exec from CD.

Other

If the file type is not recognised, unirom will fire up the hex editor.

Card Manager

The card manager offers a few improvements over the stock manager.

  • It's faster
  • You can undelete files
  • It highlights invalid files
  • You can work with FreePSXBoot cards and format them.
  • You can flick through virtual cards on a Memory Card Pro

If you're having trouble with a particular memory card, do let me know, with a photo of the card (preferably with the shell off).

Note: not all deleted files can be restored

For example if the file was part of a 3-block save, and some parts of the block have been over written.
