I am still contemplating writing in V5 support too (since i like silly
concepts), once i have the time allocated. Do your changes make this
idea easier to achieve?

Doesn't V7 (and V8 for that matter) use <NAME>.LA# files?

Neat! I was looking into AKOS myself, but i couldn't really figure out
the actual file layout as ScummVM seemed to just read all the frame
data indexed directly from the data. Will have to check this out.

1) Really? Although i guess that makes sense
2) Yes, i was wondering about this. For V6 one needed to put an object
behind the verb(s) facilitate the redraw (i guess they got tired of
doing this, hehe).
3) That was one thing i did notice when looking at the opcodes
4) Also noticed that when looking at the opcodes
Also note that you need to store character speech in a "BUN" file.
Though i'm assuming you've already figured that out. :)
I think one of the more interesting differences between V6 and V7 i
think is those SMUSH videos which can be superimposed into the current
room. Sadly though i don't think anyone has written an encoder for
these. :(
In any case, good luck with the V7 support, Alban! If there is
anything i could assist you with, i'd be glad to help.
