    old news but here it is

    The 'exploit' works on certain games (especially SNK) including Metal Slug 3, Fatal Fury Special, and Samurai Showdown II. Full details inside. *Update* Multiple users are claiming it really does work and with achievements!

    In order to unlock the full versions of these games on XBLA, here's what you have to do:

    - Download the XBLA demo of these games (obviously)
    - Launch your MW2 game
    - Stay on the main screen (where "press start is present)
    - Push "guide" button
    - Select "quick start" and select your XBLA game

    tried with metal slug 3 and it worked but failed with banjo tooie

    It's funny that MW2 is so glitchy it affects other games.

    I'm assuming it's only temporary until you exit the XBLA game. I'll try it out with LIMBO in a little.

    EDIT: I decided to try it with N+ instead of LIMBO, but it didn't work.

    Metal Slug 3 worked though. I wonder if it's just for games that are essentially ports of older games. You figure Banjo-Tooie would work in that case, but like you said, it didn't (Even though the whole game was redone for XBLA, as well as Kazooie).

    Naaah it's been confirmed working for a number of games. This is pretty old news, somebody found this out last week.

    fatal fury special wouldnt unlock for me, it asked me to updates as soon as I launched it so there might have been a patch to prevent it

    the other 2 games worked fine, thanx for telling me
    anyone find any other games?
    wanna grab as many as I can before its patched

    i have known about this for a while, if anybody finds a full list of games that work that would be great, and btw you dont have to do the exploit every time, just once, just make sure you ONLY launch it from quick launch, if you do it from library you have to re do exploit

    edit: and yes you do get achievements

    As an owner of a JTAG box this is not of the greatest interest on that front but I am interested as to the mechanisms behind it all. The difference between a demo and a full game is but a small string (this is what the so called Yaris-swap does for you).

    From what people have described thus far it looks to be the bigger games (whether this reflects on their internal file structure is a different matter) that prove troublesome for this hack.

    It is probably just a simple "yaris" check (I am not sure how the 360 loads code like this although I am betting it is external checks looking at most of their security) rather than a full blown signing check dodge but if it is the latter that opens up many possibilities (looking towards CPU key retrieval and with it region change and a few more choice hacks rather than full blown JTAG equivalent).

    Can someone who is running a working game change some of the internal files in some way (they are usually fairly simple) and see if an otherwise working game still works. I will try my own hand as and when I put my regular 360 back together but if someone can try before then that would be great.


    Also for the achievement types some of the XBLA releases are "stackable" (indeed that is usually in the directory name) so you can play the same game as it were and get multiple achievements for it. I would not be shocked if you saw the banhammer or worse for such a thing though.

    Rebuilt my 360 so I thought I would give this a go

    XBLA game used is metal slug 3- Metal.Slug.3.XBLA.XBOX360-FYK aka mtlslg3xbla-fyk (it comes prepatched but as mentioned earlier the yaris swap is a simple process, left as scene release for initial tests)
    As I was curious I pulled it apart- you have the usual achievement icons and a few ratings icons but everything seemed to be packed in the default.xex everything is on the root though (no subdirectories).

    360 of choice here is an unbanned 360, 1.6 NS firmware on the DVD, August the 11th 2009 kernel. In all cases VGA out.
    JTAG 360 used to FTP files where they need to be (not really relevant but we detail experimental setup for a reason).
    Using my slightly iffy copy of MW2 (it errors out on the main game).

    Tried a copy of sonic 2 (similar setup to metal slug 3 but has subdirectories).

    For the hell of it I also tried xexmenu- same error.

    Game not found. Insert game disc or storage device, then try again." message- this is with hacked games/homebrew though so I was not sure what to expect.

    Back to the JTAG 360 and loaded up XM360 (an XBLA manager/unlocker)- reloaded with hand locked images (237 hex becomes 00 rather than 01).

    Return to normal 360, same thing. "demos" themselves would not load from main screen (same error) so I will hopefully find a proper copy of the XBLA titles at some point and try again (alas I deleted all my "legit" demos). At present I think it is mainly just a way for a few non JTAG users to enjoy some XBLA stuff.

    You don't get banned for stacking games. Many achievement whores do it [​IMG]

    so this is permanent so long as you launch from quick launch? can someone try marvel vs capcom 2 please?
    it will be a good idea to have a working list here

    Metal Slug 3

    I can indeed confirm this works with Metal Slug 3. Going to try some other games tonight and make a list, and post back here of my findings. Currently downloading Hydro Thunder to see if this exploit works. Also going to try Trials HD, Perfect Dark, Blacklight: Tango Down, and OutRun. Just because those are some games I've been meaning to buy. Everyone on here needs to collect their findings and make one big post. This is a neat exploit.

    Alright, tried 3 games out with no success, still got 2 to go:

    Hydro Thunder: NO
    Trials HD: NO
    Perfect Dark: NO

    Trials HD and Perfect Dark both asked me to do updates, but I think it's because I cleared my system cache a few days ago. So I don't think the update was a patch.
