For the first time 4 player splitscreen coop on halo original for xbox
Patch with ppf-o-matic or ppf tool I would also recommend flashfxp5 or a ftp server able to connect to the xbox. google it if not sure
This requires a modded xbox or modded 360 with a way to play xbox original games from the xex menu or file browser within the hard drive. A copy of halo NTSC version must be installed and a way to transfer files between pc and xbox (i recommend flashfxp 5) once files have been patched and sent back to xbox you must clear cache on the 360 in case you have played any level on halo previously and for the effects of the changes to work.
