I'm running through them bit by bit. I'll get to the sound ones soon.
I managed to open a picture finally. It seems the 256 tools are meant only for SCI1.0 resources. I couldn't get them to open SCI1.1 Views or Pictures. PE256 has a really neat feaure of overlaying control or priority lines on top of the bitmap image! Handy! I'm still trying to get VE256 to open anything, actually. Every SCI1.0 view I open it thinks each cel is corrupt, gives a message saying "blown", and then complains that the View is too large and needs to be split up. Maybe something to do with the way modern reverse engineered editors create them? (I was trying to view modified views I had made with Brian's old tools)
EDIT: I tried opening some original Views straight from a Sierra game and it works nicely. Must be something in how Brian's tools saved them that made this program complain. Interesting...sad that it doesn't support SCI1.1 resources, though.
