Ok, so after my first full playthrough, here are all the bugs I can remember.
...but first of all, great work just getting this working in the first place! A great addition for any Wingnut's collection.
Some of these you already know about:
!!!! *SPOILERS FOR THOSE WHO HAVEN'T PLAYED BEFORE* !!!!!
- 'TALK TO JAZZ' shows Bossman's figure sitting in the bar. His talking face is fine though.
- 'TALK TO JAZZ' sometimes causes a random crash
- 'TALK TO KNIGHT' shows Paladin's figure sitting in the bar. Dialogue face is fine.
- On the final Dralthi covert mission, you fly through the asteroids to intercept transmissions from the Fralthi. Due the way Wing Commander 1's engine is set up, the Fralthi will almost always self destruct when you fly away, since it's still within your combat range when you run into the asteroid field on your way back to the Tiger's Claw. This loses the mission. The remedy for this is to have the Fralthi NAV point much further away from the Asteroids, so you've already gone out of range by the time you hit the asteroid belt.
- The SM2 classic: Jazz's VDU shows Bossman's image.
- After the final mission, during the debriefing, your character reports the enemy starbase has been destroyed, but then Shotglass appears right there on the hangar deck, and says "You'd better get to the briefing room immediately!" The cutscene then ends without hearing from Halcyon.
- The end sequence is from the losing path of WC1. Although, this actually fits quite nicely. (Intentional)
- Sometimes the back of your wingman's head in the debriefing scenes is replaced with the front of Halcyon's head.
I'm running the game with Kilrathi Saga SM2. Errors occur both with and without WCDX.
