One of the command line parameters in C&C's GAME.NEW and GAME.DAT files is "-ATTRACT". After looking around the 'Net, the only info that I could find on it was in a text file written by Nyerguds at http://nyerguds.arsa...xt/ccparame.txt .
Other unknown command line parameters are "-0" and "-X", but I have no idea what they do. Also, I have no idea if these command line parameters (as well as the "-ATTRACT" one are contained in C&C95 (as I only have C&C for DOS v1.22), but they may be.
Anyhow, the "-ATTRACT" command line parameter starts C&C in a 'storefront' demo mode of sorts. After one minute of idle time at C&C's main menu, the game starts up map, and then begins to play C&C (complete with units/structures/infantry/etc...)! It looks just like if you were actually playing the game yourself, with units being selected, commanded, and with the map being scrolled accordingly.
I'm not sure what map it is, but it appears to be SCM01EA (the multiplayer map "Green Acres")... unfortunately after about 45 seconds of gameplay, C&C crashes back to DOS with the error message "pure virtual function called!"
I tried a fresh install on various PCs (including my old 486 native-DOS PC), but it always crashed after 45 seconds or so of the running demo... hence, I have no idea what would happen at the end of the mission (maybe it would start another map, and auto-play it as well?).
One interesting tidbit, everytime that I started it (before the 45 second crash), the demo appeared to be doing the exact same thing (same unit selections/move commands/map scrolling/etc...), appearing to be some sort of pre-recorded demo 'macro' of sorts... maybe some kind of an unfinished 'demo recorder' of sorts within the game.
Anyways, EXTREMELY cool looking! I just wish that it would continue without crashing. Like I said before, dunno if this is old hat (or if it's in C&C95), but I've never read anything on the 'Net refering to this.
(edit) P.S. Something gives me the hunch that the "Record.bin" file contained in the "TRANSIT.MIX" file is the recorded demo... and was recorded by a guy named "bill" <G>. Although the utility "VQAtoAVI 2" reports this file as being "info for map screens (population etc)", I think it might be the recorded demo that plays back.
