Space Invaders on Pet2001
Posted: Mon Jul 11, 2022 10:45 pm
Hi, I'm trying to load Space Invaders for the PET core and am running into an issue. The PET was one of the first computers I used but I don't remember much about how it worked.
READY.
I type "LOAD"
SEARCHING
I select the Space Invaders .TAP file in MiSTer
FOUND SPACE INVADERS
LOADING
READY.
I type "RUN"
I get a screen titled * HOW TO PRODUCE SOUND EFFECTS * with a PETSCII diagram of a parallel port circuit.
I press any key and get a screen with scattered characters such as:
B*
PC IRQ SR AC XR
P
Sometimes the characters switch around and goes back to the * HOW TO PRODUCE SOUND EFFECTS * screen.
Does anyone know what is going on?
