Is Breaker Pro a PS1 or PS2 Disk?

I'm curious if Breaker Pro is a PS2 Disk, if so, it might be possible
to create an Breakerpro.elf file out of it for use with an exploit.

I know, i know, the TOC, but if you boot the TOC from a PS1 disk before
you launch the elf file it might be possible to boot PS1 backups even on a
v3-v7 PS2.

Did somebody tryed this out before?
(It might work with a backup of BreakerPro as well, just boot it from the exploit, put in your original PS1 TOC disk and swap again).

Please let me know if this might work!

I tried the BREAKER.PRO inside the disc, din't work. the files in their are SYSTEM.CNF, BREAKER.PRO, and DUMMY.000

It's a PS1 disc...

Thanks for your quick answer.
So if it is realy a PS1 disk, there still is no way to boot PS1 backups
on the old models with an exploit (damn...).

Is it possible to make a bootable PS1 file on a PS1 MC which i can boot
from my PS2 MC via ULaunchELF?

.. breaker pro will boot PSx backups on your PS2.

breaker pro is a pressed PS1 disc, The ps2 can play ps1 games so thats why it can boot breaker pro. You cannot use an elf file because I do not believe the ps1 uses elf files. just use a chip or the switch method

Exactly

PS-X-Change 2 is also a PS1 swap disc for booting backups.
The CD contains 1 file called PSX.EXE. Is it possible to boot PS-X EXE files?
(It's not an ELF file)

Edit: the BREAKER.PRO file is also a PS-X EXE file.

i thought breaker pro booted backups on ps1 and ps2 i thought it came with an extra disc for the ps2 or something.

no, it's a single disc that works on both the psone and ps2 systems because, technically it is a "pressed" disc as was stated a few posts above.
