Short intro: I'm a Sierra&Lucas fan for a long time and have been following this emulator for sometime. I couldn't be ever happier when latest version finally support SCI engine. And so far I have replayed and finished 3 Sierra games. Kudos for the job WELL DONE!

Right now I'm playing ICEMAN, the known nightmare Sierra has ever been created. Last time I played this (either on Dosbox or the old Pentium 166) I kept scratching my head in frustation, although at the end I managed to finish this freak of nature.
Still, the charm it has and the chanced ScummVM gives has entices me to replay this game again, plus I'm kinda curious to actually attempt to finish the last minigame, which was (almost) impossible to win.
And yet this emulator gives a new challenge: Doing submarine sessions without being able to save midgame. Why? because every time I did that and restore, it crashes and produces error:
"GfxPorts::kernelSetActive was requested to set invalid port id 3!"
It has given me this error starting around the second submarine session. And I can forget that savegame because it will crashes everytime I load that save file.
Imagine what I've been through with the first sinking mission then the iceberg navigating nightmares.

(luckily I can still resort to cheat engine to help me get by).
Alas... right now I'm on the last submarine session, which is: sinking enemy sub and following a friendly battleship, represented by a cross mark.
I can still get by the sinking mission using cheats, but following the cross mark are not easy.
I've tried to make a savegame after the sinking minigame, & when trying to restore: lo and behold! the same error occured. I have to play from the sinking minigame all over again.
I hope this bug can be fixed very soon, or perhaps anyone can give me a suggestion about how to get by this problem? At least when I'm playing using old computer, I can still use savegames midway.
Waiting in anticipation!

Btw, there's also another bug although quite minor and it's on another game (just fyi):
- Eco Quest 2: BGM getting silent on certain part (much later, I think it's around the bat caves part), but triggering dialog box produces the correct BGM.
- Police Quest 3: I think there's a fatal crash on Day 1 at freeway and that savegame gets corrupted (showing the same error when crashing). I don't really remember much since it can be easily avoided and already succeeded in finishing the game again.
