Re: SEGA's arcade rendition of CHOPLIFTER my favorite 8-bit game as of late

Say, thanks for all the feedback and discussion.
I tried the POKE 48984,192 but it didn't work. It starts up Choplifter
but just when the tank takes its first shot, the system freezes (or in
the other CL, it exits the program and displays a P on the screen).
How does one POKE a zero? I tried POKE 0, 192 but still got the NO
BUFFERS message.
The POKE I suggested isn't to location 0, but a value of 0 at location
48984. It will have the same effect as the POKE of 192, except that
it also leaves pages 0 and 1 unprotected--which is irrelevant, since
BASIC.SYSTEM and ProDOS will never get control back after the BRUN.
Anyone got this running on a //c+ yet?
If I had a //c+ out, I'd give it a try...
A related question... if I want to set up a 3.5" startup disk with
ChopLifter on it... which DOS related files do I need? I formatted a
disk using ProDos-- obviously that's not sufficient. I then copied over
a ProDOS file from a //c system utils disk... that didn't work. Then I
added the BASIC.SYSTEM from a Multiscribe diskette... and it boots up
with a title ProDOS BASIC 1.1 ! I guess I better copy the BASIC file
from the sys utils, too. Should that do it?
Since Choplifter seems to work after being BRUN from ProDOS, you don't
need any DOS files, but you will need ProDOS and BASIC.SYSTEM, plus a
STARTUP program that POKEs 48984,192 (or 0) and then BRUNs Choplifter.
ProDOS can only run SYStem programs unaided.
