Helping Cxbx for dummies

[blueshogun96]

This is a little helpful guide that I came up with for those who wish to help Cxbx project, but don't know about programming (and no, I'm not calling non-programmers dummies).

1. Reporting missing kernel functions: These are easy to find, implementing them is the hard part, but don't worry about that. Whenever you try to emulate a game that crashes (i.e. gives you the "Recieved exception" message), look at hexadecimal number to the right, if it's a hex number between 0x00000001 and 0x0000016E, then that means the crash is caused by a missing kernel function. If it's anything other than that, forget it. Send me a PM and this hex number if you encounter this. I've added a small handful of missing kernel functions already and they are working great. There's an example image below with the important number underlined in red.

2. Finding rare/unimplemented XDK versions: If any of you have any Xbox XDKs that Cxbx doesn't recognize, pass it along to us (me, Caustik, shadow_tj, etc.) and we can see if we can get it working. Examples of rare xdks include 3944, 4400, 4721, 4831, 5028, 5233, 5455, 5788, and 5933. There are more, but thats all that I can think of at the top of my head. To check to see what XDK version your game is using with a trace build of Cxbx, go to View->Debug Output (Kernel)->Console and enable logging through the console. The first thing you should see is Cxbx locating Xbox APIs by their XDK versions. Look where it says "Locating HLE Information for xxxx...", if it says "Skipped" after each one, that means that XDK is unsupported. If you have that XDK or know where to get it, let us know.

Well, thats all of the really useful things I can think of for now. Wanna help? Now you know how!

@shadow_tj, if you have anything else to add, by all means, go ahead. Thank you sir
