I'm not sure if this is known, but I made a discovery with this game that I posted in /r/xemu: The demo disc (NTSC-U region) to this game loads just fine in the latest version of xemu (0.7.118). Not only that, it plays great!

Could something simple be stopping the full game from loading?

@CosmicStardus could you share more? which exact iso you got?
I'm trying with xemu 0.7.119 usa and eu img and doesn't work, stays for ever in logo.

I can confirm that this issue does not exist in the "Demo" version of this ISO, and the game actually plays just fine.

If a dev is interested in investigating this, I am willing to provide a working xiso so that this can be investigated further. Just need to know what the best way would be to share it(don't want to break any rules or DMCA's, even if this is a demo disk, just playing it safe unless otherwise told).

Bumping this thread. Anyone been able to get this working with any new updates or bios?

As of the current build on USA Xemu 0.7.127 result is still the same as above.

Maybe it's something like FIFA, in 07 when you package in common ways the iso doesn't start, you have to do it in a specific way or download it from a specific site. It has to do with EA and there must be an iso lock that the demo does not have, it could be the music

It could very well be.

All I can say is that both versions of the ISOs I have tried are both re-dumps that have been patched the same way to work on xemu.

I tried taking it upon myself to try and seeing what the hiccup could be, but I discovered everything is in Assembly (or at least I think it is, no idea) and unfortunately this makes me as useful as (something very useless here).

I still have both fixed re-dump files available to any developer who would like to investigate this. Thanks!

Does this even run on a real machine?

If you mean the game, Yes it does. This is played on the original xbox.

[papadkostas]

I mean if the actual ISO(not the demo) is even working on the real console? Just to exclude any other problem.

[PayrollG]

yeah it never work for me when i play on it i was stuck on the intro how you fix this intro

Bumping this thread again. I love this game, used to play with my older brother and a cousin for weeks.
We didn't had the original disc, it was an ISO.
Do you need this ISO for investigation?

[Steff833]

I Bump too :p. Pisses me off that no one found out since years. Xemu dosnt hang. Maybe it is some sort of copy protection in the games default.xbe. Def Jam behaves nearly similar like burnout3 but with a difference. You can boot burnout 3 via iso file. But you cant load the game via virtual Hdd. For example via a dashboard like xbox media center. Burnout has then also an infinite loading screen. I also tried to load these two games from other dashboards like Avalaunch.

My old real Xbox console dosnt care. It boots both games perfect no matter how. From hdd XBMC or DVD. Btw. I copied and replicated my complete Xbox to Xemu. I Extracted the bios from the Chip, use the same eeprom, the same HDD Key, the same Xbox media Center as an OS.

Normally (with the same bios) Xemu should now behave exactly like the real hardware. Only def jam and Burnout bitches around.

Tested on HDD and made no difference.
