Update docs: SCPH-77000 can't run PAL disks, PS1 backups work without any modifications. #72

Closed hikkamorii closed 2 months ago

hikkamorii commented 2 years ago

Hello everyone!

I decided to check out MechaPwn on my Japanese SCPH-77000.

Looking at other issues, seems like the documentation is incomplete because 75xxx+ are not always capable of running PAL disks (unless the region is PAL on Vanilla console of course).

Another interesting thing that I've noticed is that PS1 game backups work, at least NTSC games on NTSC consoles do.

Install FMCB cross-region! Please try this Release Candidate - it should allow all regions to work.

Tried the release candidate, and all the issues fixed! Good job! I had to reinstall FMCB from another MC for some reason though, it was boot looping, no clue what could've caused it since both of the cards had same version region free FMCB installs. In any case, that all is great!

Currently, MechaPwn readme has incorrect readme: you need FMCB cross-region install, FMCB multi-install will not work. Anyway, thanks for testing.

Yes, I understood that, the multi install is grayed out in installer.

BTW, when launching PS1 game you can see that there is no region code under PS logo (for example SCEI for Japan), which I assume means that the region/backup check is not active in PS1 mode at all, at least on SCPH-77k(my fat needs a new PSU). I was able to load burned PS1 disk of NTSC-U region on my JP console, I assume PAL will work too, but as with the original disk you'd have to force PAL mode using GSM for graphics to render properly, but can't test for myself.

PS1 video modes are a bit of a strange thing. It looks like PS1 has 2 NTSC and 2 PAL modes and it is a bit hard to catch the differences between all of them. I personally cannot test, cause i don't have working laser. https://github.com/MechaResearch/MechaPwn/issues/54 and https://github.com/MechaResearch/MechaPwn/issues/68 are reporting about PS1 titles acting strange. It looks that NVRAM has some value for game frequency.

Anyway, for changing between PAL/NTSC it is better to use PS1VModeNeg

Interesting, I don't see issues mentioned in #68 either on a real TV, or a Capture Card. The only issue I had is the wrong resolution and framerate, maybe it's only related to old version of MechaPwn?

You used Japanese console right ? It works fine on those, it's a pal console only issue the #68

hikkamorii commented 2 years ago

@Thexterax I assumed I should experience similar issues when running PAL games on NTSC console, but I did not. It's rather weird that the PAL console is affected by the video system change, and NTSC (at least JP) is not...

RC2 was removed due to a major bug. If you are using FMCB, install FMCB cross-region. Please try this Release Candidate 3 - it should fix your problem.
