I have a few distribution of CnC 1 (Tiberium Dawn), including Nyerguds' 1.06c, and this problem seem to be common to all of them.
When turn on the computer and I start the game, sometomes it doesn't load up. That is, the mouse icon changes into an arrow with a hourglass, and after a few seconds returns to the normal arrow. No game lanches, although the "C&C95" process is still active. A couple of times I tried to launch the game, failed, and then lanched a different distribution. If it worked, then I could exit it and launch the first distributon successfully (until the next time I turned off the computer). Also, one time I tried to launch 1.06c, failed, and then installed the Video pack. After that, the game launched (until the next time I turned the computer off and on).
Also (may be connected), the game tends to freeze in the middle (in one distribution, it always freezes when I complete the Dinosaurs mission 1). it tends to freeze again at the same point, that is, if I save the game, continue playing and then it freezes after (say) a minute, and then I quit to Windows, kill the game's process, re-runs it and loads the mission, it'll freeze again after a minute, no matter what I do in that minute.
Windows XP, CnC 95.
Thanks!
