If any of you guys could make a very simple tutorial for us noobs to unlock and play these games modes that would be great (IMG:

Also does anyone know how to mod the game i.e (more ammo in clips, higher jump etc). Is it a case of just finding the relevant section and hex-editing it

any help would be cool thanks
I didn't write this, just found it
K, you're gonna need a few things.
SimplyZip
A Hex Editor
Notepad
A copy of code_post_gfx_mp.ff
Now, make a backup of your code_post file, just incase you screw up.
Open code post, and navigate to offset 0x4025. Copy from the 78 DA all the way to the end of the file.
Put this into a new file. Name it "code_zlib.zlp"
Open up SimplyZip, hit external tools, ZLib. Open code_zlib.zlp and select "decompress". Hit OK/Go/whatever the button is called.
Now, open up code_zlib (no extension) in your hex editor. Search for "buttons_default.cfg".
Look for the next 78 DA after the cfg name, and copy until just before the first FF FF FF FF.
Copy into a new file, name it "buttons_default.txt.zlp". Decompress it.
Open the text file in notepad. Edit it like so:
Remove all DPAD binds except DPAD_UP. Make DPAD_UP do this:
bind DPAD_UP "exec developer_mp;scr_xpscale"
Its the only way I could get it to work. Save, compress. When you compress it will automatically overwrite the zlp file. Copy the new zlp file into the decompressed code post, overwrite the previous data.
MAKE SURE TO KEEP THE SIZE THE SAME. If the size is smaller, add 00's until you reach the FF FF FF FF.
Now, open the text file in the hex editor. Note the size. Go to the FF FF FF FF's just before buttons_default.cfg in the decompressed code post file, and it should look like this:
FF FF FF FF __ __ __ __ XX XX XX XX FF FF FF FF buttons_default.cfg
Ignore the __ __ __ __.
The XX XX XX XX is the filesize of the decompressed text file. Fix accordingly.
The highlighted bytes are where the file stores the filesize of the uncompressed cfg. Sorry if it was confusing earlier.
Do the same for developer_mp.cfg, except inside of developer_mp.cfg, put the following:
If you have binded any buttons, (I recommend only binding the non-start/back buttons),
bind DPAD_UP "exec buttons_default"
Now, just put dvars in there as you see fit. Now, the dvars for XP mod are as follows:
set scr_xpscale 50000
set xblive_privatematch 0
For any mods to stick, you must bind "fast_restart" to a button. Then press that button when you have the mods set up.
Now, when you are all done modding and such, compress the decompressed code post file, and overwrite the original file. MAKE SURE TO KEEP THE FILESIZE THE SAME. As before, add 00's.
