I am busy on a same kind of scroll, it's for an engine for a
smooth-scrolling RPG!!! (Yeah I know, it's cool).
It works something like this:
10 SCREEN 5:V=VDP(19) AND &HF0
20 FOR I=0 to 15
30 COPY (I*16,0)-(I*16+15,211),P TO ((I*16-16) MOD 256,0),1-P
40 VDP(19)=V+(I XOR 7):NEXT
50 P=1-P:SET PAGE P,1-P
60 GOTO 20
This should work (however not tested).
This is really cool. The clipping of the right/left borders can be masked
with black lines (not with sprites, for that slows down the VDP too much).
On the bottom of the screen is a border, like in SD-Snatcher or Pumpkin
Adventure II, which I made using a marvellous screensplit.
I think that if my engine is finished, I will put it on my webpage. It can
be used for several kind of games, for example RPGs (Strategic Army 0.5!),
Real Time Strategy-games (SA but I think I won't use it; scrolling is still
too slow) and Grand Theft Auto-like games (using JoyNet!)... And, ofcourse,
when the computer it is running on is a MSX2+, it will use the features of
the MSX2+. And if you really need the speed, you can make an option that on
a normal MSX2 it can only be run in 50Hz-mode (then you've got more time
left for the COPYs).
I don't know why games like SD-Snatcher, Nemesis, Dragon Slayer, Akin,
etcetera scroll 'liquid'... (why, why???). It should be possible... Is it
that they (the developers) are not as smart as I am? I can hardly imagine...
Fortunately, Space Mambo scrolls 'liquid'... But that game is programmed in
screen 4 (which I can imagine if you need that much sprites and animation).
And by the way, does Illusion City already work on the Emulator?
And by the way 2, is Moonlight Saga being translated into English?
And by the way 3, is the new "RPG-subscription" of Umax very cool?
And by the way 4, I got stuck with the Lost World... Is somebody who
finished it willing to help me out?
