PSP Pro Cycling ISO hacking
alisdairmills
I've had a poke around the ISO of the PSP Pro Cycling Manager games to see what would be involved to update the databases and graphics.

The database is a cdb file... are the any database editors that can open the PSP database or if not is there any documentation available regarding the file format?

The graphics use a file format I've not seen before (vpi) but have had a poke around and the format seems to contain the pixel data at the end of the file. i have written something to turn the bytes to RGBA but it seems that's not the correct format (see linked images of the KOM jersey texture, TdF logo and English language select texture).

Anyway... just wanted to see if anyone had any info on the PSP file formats (cdb and vpi) and also if there would be anyone interested in having the ability to hack the PSP versions of the game to have custom database and graphics.

You could try one of the PCM Editors (listed in the Latest Downloads section on the right).

PCM databases are CDB also, and those editors work with them.

It would be great if someone figure out, how to make database for PSP Pro Cycling... I think it would be enough to edit team names and assign actual rider to them.

Had a bit of time last week to look into this again and made quite a bit of progress. Just to get this out there in case anyone else ever wants to mod the PSP ISO - the only editor I found that could edit the database was Hannes Convertor.

As for the VPI files. Essentially they're 32 bytes of header, then 256 RGBA bytes (so the next 1024 bytes). Then a byte for each pixel referencing a colour in the list of RGBA values.

I've created an ISO with the teams updated with the current pro tour teams. complete with riders and stats. I've also team jerseys, logos, and rider photos. I've taken a video of it running in the PPSSPP emulator (I've played it on my PSVita too and it works there as well).

If anyone is interested in testing it then send me a direct message (obviously I can't redistribute the ISO here).

Man, that is sick! It took me a while to find someone working on the psp version, since for a long time that was all I had. Is it only the 2009 version that is moddable? By the way, any new progress in 6 months or so?
