: have this happened to anyone? couple years ago my commodore was acting really weird... The Joystick port, video chip or something similar was damaged...
: like when I played karate kid or other game, the guy scrolled always to right even I didin't press ANYTHING.
: Well I found out if I kept pressing G(?) the "BUG" was removed. So I just put a piece of tape on that button and games worked perfectly.
: When I removed the tape from the button and watched the Jumpman's intro (Guy drops the letters and forms the word jumpman) there was that bug again. The guy just kept running on the right and falled down from platform! in intro! is this suppose to happed randomly or is it at my C64? I tried to control that guy (with G pressed) with joystick at both ports and I couldn't
: control the guy. I don't have that C64 anymore so I cannot try doing it again...
: Sorry that this post got so long and the explaining isn't good (I'm from Finland)
: but I just wanna know what kind of damage (virus?)could do this thing????!!!!
It sounds like one of the VIA chips might have gone bad. These chips control both keyboard and joystick function so this could (maybe) explain the thing about the "G" key.
Jumpman has a funny bug where you can mess up the intro by holding the joystick in a direction at the very beginning of the intro.
I have a C64 where a VIA chip has gone bad and the "Down" on joystick port 2 stopped working. I was able to switch the two chips, but that caused video bank switching to stop working, resulting in badly garbled graphics. Now I just use CCS64 and I haven't had one of the emulated chips go bad yet.
