Idea about different XDK Versions

[caustik]

nice chipsugar, you summed it up accurately. Im glad somebody understands.

[shadow_tj]

ok you all tell that the higher the xdk version how more bugs there are fixed with it.

ok my question as developer.
is the Microsoft XDK Downwards compatible ?

if so why don`t use the last xdk version then all the others need 2 work also.

greetz, shadow_tj

I'm going to take a stab at filling in some details here too... I haven't looked at Cxbx's source so I could be completely wrong, and if so caustik should whap me over the head for it.

Cxbx is very much a high level emulator, and the fundamental aspect of a high level emulator is to analyze the functions called by the native code and match them to functions from a known library. This has two important implications:

1) The only 100% accurate way to match a called function with a known library function in HLE is to analyze the actual contents of the function being called with the original. Because of this, even a very small change to any of the source functions will completely throw off this analysis process. So even though the base functionality of a function may be the same between XDX versions, any minor changes (optimizations, bugfixes, etc) will completely throw it off. Therefore, every distinct version of the function needs to be explicitely supported. Some HLE implementations only look at select bytes of the function, but even this can easily change with minor alterations.

2) Because the function itself is needed that means that the author must have access to a binary compilation of the original XDK library used. Naturally the headers accompanying the XDK version itself are also important so that you know the exact call signature to look for (another aspect in pinning the function) and so that you can get an idea of its usage/behavior. Because of this the XDK version itself is needed to properly emulate it, and as caustik and others said, older versions can be very difficult to obtain. It might be possible to reverse engineer XDK functions from the XBE's themselves but it'd be a lot more difficult.

Again, I could be way off on all this so if someone knows better PLEASE correct me.

and how do you find out what games have what ver of the XDK?

EDIT: Ah, righty, second post? how could I miss that??? Someone buy me laser I surgery

[chipsugar]

DC_daNMan: Re-read this thread from the beginning.

I think one of the posts has skipped your attention.

[kcar181]

Black Stone - 1.0.5028
Blood Omen 2 - 1.0.4134
Midtown Madness 3 - 1.0.5233
Tennis Masters Series 2003 - 1.0.4531

Ok... i made an application that tracks the XDK Versions of games... you can download it here sorry about the username/passowrd but i have limited bandwirth and storage. You will need the .net framework 1.1 (XP/2k users that run windows update reguraly will have it). I'll process the username/passwords as fast as i can. Hope you like it... i can add features... but the most importan thing about this is to help Caustik so if he doesn't think there is a need for it then it will stop at this.

I would love to be able to have ms send me a development kit they have there own emulator with it u load your files and emulate it on your xbox and tv they use a pci card that goes in your pc and a cable goes from the pc to the xbox. too bad its not done only by software and its only for businesses mostly. anyways in a sec im posting a link to exploit to play homebrewed software on a unmodded xbox

While that has nothing to do with this thread whatsoever it's still very interesting. You should post it in one of the other forums.
