    Hello! What would the forum estimate the value of this pre-production UMD to be?

    It's dated six months before Grand Theft Auto Liberty City Stories came out, so that's my guess as to what this is a fairly unfinished build of.

    I'd be happy to except I don't own a PSP myself.

    Would a retail PSP play pre-production UMDs or would it have to be a dev kit?

    Not a 100% sure but I've seen people say you can run most on CFW PSPs.

    I think you can play on a retail psp and the other way is extracting the iso on a computer and play it on a emulator but you would need a psp of course.

    Very glad to see this disc for the first time, i was looking for it too since ages :)
    You can play this disc on every console, retail or devkit. Eventually on an emulator too, but you'll to dump it first.
    If you want some help, just send me a shout.

    I've booted the UMD on a PSP with CFW. The UMD does not boot to playable code as it appears to have some kind of security protection.

    The contents have been dumped though and it's undoubtedly GTA Liberty City Stories. Here's a link to video of the UMD booting up:

    Note that the triangle only stops spinning when the Select button is pressed. All other inputs have no other effect.

    Here are a few screenshots:

    And here's a pastebin to the UMD's file structure, including directories and filesizes:

    I've just been looking through the ENGLISH.GXT file and it's got all the mission text, dialogue etc. in there.

    If there are any particular files worth exploring that I can post some samples from which might be of interest to the community, please let me know. It's possible that the code expects a security key on a memory stick to run straight off, but I'm assuming these files can still be investigated etc. now the contents have been dumped.

    Wow, the texture archive format is different. It's using TXDs instead of CHKs, just like the preceding 3D games in the series that used Renderware. A lot of the game's core files are also stored loose unlike the final version. ENGLISH.GXT is much smaller here too, 407,312 bytes compared to 526,336 on the retail disk.

    The filenames of the radio stations match GTA III's, which is interesting. It's possible it's using III's as placeholders, but there could be different mixes here. GAME.AT3 in particular is cool to see, as Game Radio isn't a station in LCS. There has to be a lot of differences in general, but I wouldn't know where to start. This is a great discovery for sure, OP.

    these would be cool
    Code:
    FILE    ---A----    31/05/2005 18:09    1,121,859    MAIN.SCM
    FILE    ---A----    31/05/2005 18:09    2,248,000    MAIN_DEBUG.DBG
    this build must have something like that inside

    I have 10-15 psp mem-sticks that came from rockstar. Anyone have any idea what to look for in terms of drm key-file?

    FILE ---A---- 22/05/2005 17:31 67,149 BOOT.BIN
    FILE ---A---- 01/06/2005 17:36 67,488 EBOOT.BIN
    Pretty looks both executable files just only a Triangle demo, but other files based on VC engine (TXD, DFF and IPL).
    There is also many text files (HANDLING.CFG, etc), but looks like game doesn't use it (because its precompiled into game2.dat)

    Sort of confused by that post. In PSP-DVDs used in PSP devkits there is both an EBOOT and BOOT executable. The EBOOT has some devkit overhead and will not run (afaik) on a standard PSP. So when wanting to play a PSP-DVD on a PSP I simply rename or remove the EBOOT.BIN and then rename BOOT.BIN to EBOOT.BIN. I use PowerISO to open the dump and then save it as an .ISO (credits to approach goes to Borman).

    So like I said, confused with that post but if there is both BOOT and EBOOT on that disc then dump it and use the mentioned approach.
