How to play PSF files with the Playstation?

Post by hally » October 24th, 2013, 11:46 pm

Hi all,

I'm a newbie here so please excuse me if I say something strange.

Is there any way to play PSF music files with the Playstation itself?
As PSF files might not be intended to do that, SEQ/VH/VB general purpose player for the Playstation is also welcome if such a software is available.

All the best,

a PSF file, not that i know of... but u can use PSFLab to revert (uncompress) a PSF back into a PSX EXE that can run on real hardware.

A SEQ/VH/VB general purpose player is totally possible (and quite easy) to make :) -Do u want one?

I extract SEQs and VABs all the time from uncompressed PSF files for use in my project, but i've never had a use for a general use VAB player. I generally only listen to music on my computer only :P

This is what i do... first find a PSF u like, then convert it to a EXEcutable. Then use a program called "search v1.1 reptile"
If the EXE has standard format VAB SEQ data, the program will automatically generate a TXT file with their addresses. At that point, just use a hex-editor to "cut them out" ... now rename them to either .VAB or .SEQ and u got the original uncompressed data for use :D

Hi isufje,

Thanks for your reply. Yes, I'd love to use a general purpose player!

I want to listen to some game soundtracks usually not playable without problems on the real hardware. I've already extracted SEQ/VH/VB with the way you explained. Please consider the player if it's quite easy to make :D

About PSFLab thing, I also tried to play the reverted PSX EXE on emulators. However, don't know how to merge a PSF file with psflib file...

I would also love a player where we could compile PSF's into a bootable ISO for CD-R and PSX.

hally As far as I know you can't just load a PSX EXE file to the real hardware, you will need to compile the exe using a format tool to the proper (and bootable) ISO and then burn to a CD-R. I haven't played with PSX in years but I recall hacking ISOs and screwing up the format that PSX thought it was an unknown CD. If you have a PSX EXE it can't just be slapped on a CD and expect it to play.

I do know you need to get past the BIOS protection as CD-Rs won't boot on standard PSX/PS2 hardware but guess these days people use a bootcd? Mine was chipped years ago so not a problem. Of course you could also play it on a soft-modded PS3 but it will be emulated just like PC players.

A seq/vh/vb player that could be added as a plugin for Sicklebrick's UniRom would be very welcome.
Something based on Mark Grass' generic psf driver for example.

Why not program one? :shrug

You'd have to do a search off of the CD-ROM in real-time for VH headers so you know what file is what. However, some games wont work because the developers encrypt or shuffle/scramble the data around for security. Some will add them to a single file and buffer though them like a tree list (EG: DATA.BIN (not a disc image, but data)).
Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34.

I would if i could. :mrgreen:

As for getting the data, that part isn't a problem for me as i already made and released some PSF sets almost a decade ago.
Some used standard psyq format, some were Sony's custom format (eg Arc the Lad 3, Popolocrois 2, etc...)
But until now i always used generic drivers or recycled others (Wild Arms 2 driver for those mentioned above.)

My lack of knowledge to code my own stuff is what brings me here so maybe one day i'll be able to learn enough and go on my own. ;)

If we had one example in playing the sequence set (seq/vh/vb) we could certainly do something. I think theres no example of doing this in the example's area...

I got one on my Windows 98 PSX development machine. I'll have to upload it at some point...
