MOH:AA Demo recording "that works"
--------------------------------------------------------------------------------
Found this over PMOH, not sure if already been posted. Please backup you original EXE file.
MOHAADemo v1.0
This is a patched MOHAA.EXE (Medal of Honor: Allied Assault v1.11 US) that lets you record and watch MOHAA Demos. It works like in other Q3 games:
*** RECORDING A DEMO ***
g_synchronousClients 1
record demoname
*** After you start recording a demo, set g_synchronousClients 0 ****
*** STOPPING RECORD ***
stoprecord
*** PLAYING A DEMO ***
playdemo demoname
