the number of players is variable and adjusts to the screen size actually....
ie, one tetris playfield is 10 chars wide and as many of them fit on the
screen will be used! (meaning 2 players on the vic20, 4 on most others, and 8
players on the PET! yes! :o))
btw never mind the bug that a line sometimes doesnt get cleared immediatly :o)
i am wondering myself that this works after i slammed it in from memory (did
sth like that on gbc before :o)) hehe

i gotta say that i personally checked on every (emulated) machine that is
handled by VICE, so it should run allthrough the cbm-family.... i wouldnt
doubt that any other target could run it though, nothing fancy in there :)
btw the vic20 conio-library seems to have serious problems with colors and/or
revers characters..... something seems to be screwed here, couldnt get it to
work properly with colors (without fixing the lib that is, which i didnt :o))
so who is responsible for that part (uz? :=P) and could give me some pointers
where to look..... and since i know rather nothing about vic20 (it got
simelar case as c64, less memory, awful sound... now thats it ;=P) i wouldnt
mind some basic memory map, kernal disassembly etc (the usual crap :o))
either, maybe someone hot that laying around....saves me from surfing the web
and dig through stuff myself :o)

mmh well, both the protovision and my own (dxs&hit) 4-player adapter need some
more code than usual joysticks do.... however since including all the code
for all the adapters (there are some more even more obscure ones, including
the crazy 16-joystick adapater from oliver stiller :o)) i guess those
loadable modules are the only reasonable solution (we wouldnt want to end up
with kilobytes of unused joystick-driver code eh? :0))

mmmmh using VDC mem in c64 mode would be major cool.... that would finally be
a reason to use that one and only acceptable c64 emulator :o))))))))

copying byte-per-byte should be fast enough for many applications anyway....
ie, the action/retroreplay rom does that in many places aswell and you rarely
notice it. (in monitor disassemble 0-1000 and notice the different speed in
0400- and 0800- area :o))
