    There are many tools to extract the kernel(if you have the right keys) such as XBTool, evtool, a few others in the xbox-scene.com download section. I'm betting the kernel isn't anything different, just encrypted with a different key.

    I should rip my chihiro apart. I don't really know how that hardware works. I wish there were some official whitepapers on it.

    The interesting thing to me was this was in 2004, well before most of us knew the file structure etc of chihiro games and he states he was able to run crazy taxi from chihiro on his 64mb xbox.
    Unfortunately, no one believed him and he was banned as they thought he was full of it lol

    he did his own dump though and said he got 908mb of data, i looked at crazy taxi dump and its only 400mb or so....make of this what you will. But no one else seems to of had any chihiro games running on xbox apart from virtual cop 3...

    Had some spare time so had a look to see if a couple of Chihiro copies would run, first tested on my 128mb Xbox with Ghost Squad (same as everyone, boots up but freezes while loading level) and tried Crazy Taxi High Roller (doesn't boot up). Then thought I would try my Jtag Xbox 360 with hacked compatibility files for xbox 1, Neither booted up. Properly been tried by others but hadn't read if people had tested jtag with hacked files etc

    Please EDIT your posts - HEX1GON.

    Thanks

    I tried too on hacked xbox, but does not work, cetrainely because sega/MS doenst code the update compatibility. No, to have one chance to run it it's to decrypt the chihiro bios or see why virtua cop 3 test version run.

    Vcop 3 test mode doesn't boot for me, but vcop 3 itself boots fine. But only if I load up mameox first

    All I know for a fact is that the Chihiro uses the DEVKIT board of the XBOX, so it might also explain why VC3 actually works well since it's basically the same hardware. All other games probably have some sort of attachment etc to make them work, with the combination of more RAM.

    But what is strange about this is that the Chihiro seems to use the MCPX found in the DVT3. Despite this, VC3 actually works worse in the DVT3 for whatever reason.

    Maybe it's been overclocked in a way? I'm not sure, though it's very interesting that you mentioned it.

    Its more that VC3 on the DVT3 only seems to run at 480i.

    So Boomslangnz sent me an interesting PM.

    /puts on best Yoda voice : "There is another."

    Ehem. So it turns out, that right in front of us (and even on my PC, go figure) for the past few months was another game that runs on the Xbox (with 128mb of RAM of course). The Outrun 2 Beta! It is unclear whether it a library difference that allows this one to run, or some other software quirk, but it certainly works. The proof is in the pudding :

    thanks for the share.

    I tried to extract one time withroot670, but the chd file doesnot exist, could you explain how to do it please?

    It's a very good news, we have now two games works, the bios, we have all we need to run the arcade version, one guy could help me Yoshihiro a french programmer but I dont manage to contact him.

    Yeah it's pretty cool! Just a note that I did obviously try the non beta Outrun 2 and it doesn't boot at all. The Beta and Non Beta both have the same files actually, obviously just modified slightly for when it was released, so I copied the Outrun2.xbe from Beta to Non Beta to see what happened. It Boots up actually, however with some menu graphical errors and again ingame with a little graphical problems again, after around 30 seconds of racing it locked up. So perhaps someone can check both Outrun2.xbe's are see why one boots and the other doesn't.


    ****UPDATE****

    Anyone keen on Ghost Squad? I have it working :congratulatory:

    Got past that pesky loading screen

    Really, ghost squad boot and games doesnot freeze in loading? arcade or test version? How to work it please?

    For Outrun 2 beta I test it and run fine, I think the testmode.xbe it's the arcade version with option mode. It's seems like some of differrence:
    What I m not sure, it's my impression:
    -alliasing seems like lower in beta version
    -the frame seems like fluid
    -the image seems like zoom

    and What I m sure:
    -arcade global desing
    -only one bug graphic : tricolore light doesnt appear at the begining
    -some of voice is missing (like game over)
    -in outrun mode in xbox version the frame is low some time (tulip garden for exemple), in beta version no problem. In xbox in attack mode when some of heart appear the frame will be low, I dont test in beta version maybe like the first exemple is better.
    -option mode/testmode doesnt work

    I have been following the progress of this topic for quite some time now, and I also remember the specific post from way back (as previously discussed in this thread) about a guy who presumable had Crazy Taxi 3 Chihiro working on XBOX (If I recall correctly he also posted his findings on this very board). It's really nice to hear that more Chihiro games seem to work on the xbox! Thanks to all who have made this possible, and Boomslangnz keep up the good work! Now if only you could also discover how to get Ollie King working _O_ :)

    Ghost Squad has a long ways to go before it is truly playable, the only way to get it to work is to delete files to free up RAM. Working on seeing if I can downsample anything (audio downsamples fine, but that isnt enough).

    CT3 surely doesn't work for me at all. Has a RAM issue which I believe CT3 uses 512MB of RAM :/

    I'm pretty positive that the games don't use more than 128MB, and that they are using the Xbox's memory. I believe the 512MB/1024MB memory is only used for storing the media, like a dvd drive/hdd. I don't think any temp memory is accessed here.

    I can't prove this (yet) but maybe this weekend.

    Thats for the DIMM board. But I looked into it some more, and some Chihiro boards do seem to support more memory modules, but who knows. If you want proof, delete a few files from Ghost Squad, and itll load fine. Who knows though. Im really torn on the issue. I know the DIMM is to load the game files, but there was still talk of different motherboards having more ram modules.

    More DIMMs or more RAM on the Xbox motherboard?

    From what I've seen, all of the Xbox motherboards are exactly the same from type 1/type 3. Mine is a type 3 with 512MB and looks like every one I've been able to find. The extra DIMM I could add is just for storing a larger game.

    Yeah so far it appears to be all about insufficient RAM but if it is, it isn't by much.
    We are gonna try some stuff and see if we can get it better, Stage 1 and 2 load. I played through Stage 1 and its mostly fine (invisible doors and invisible helicopter at end, with a green square around it) so you can still finish the Stage fine. Stage 3 still doesn't load
    Hopefully we can get it near perfect
