I'm succesfully using this mod with my Sony PVM monitors and the pictures is perfect, it couldn't be any better.
I recently got a Commodore 1084S-D1 monitor but with it I only get an extremely distorted picture, it looks like a sync issue.
Any idea what the reason for that could be?

Re: New interpretation of Pitfall! for PAL Vic + 16K
I think this is absolutely amazing.
It doesn't even look and feel like a VIC-20 game.
Congratulations and thank you very much. It's a 10/10 from me.

ML routines library?
Is there a machine language library somewhere?
I feel like having to reinvent the wheel time and time, or ask people on this forum for help, when the code snippet I need probably does exist somewhere...

Re: Joystick assembler routine
Thank you, Rob, your routine works great too.
It moves my little character all the way across the screen as well, so I need to see if I can get the de-bounce routine from above to work.

Re: Joystick assembler routine
I see, so do you think
JOY_PORT_READ_MASK = JOY_PORT_UP OR JOY_PORT_DOWN OR JOY_PORT_LEFT OR JOY_PORT_FIRE
would do the same thing in CBM Studio?
It also doesn't like this line:
and #<(~JOY_PORT_FIRE)
JOY_PORT_READ_MASK = JOY_PORT_UP OR JOY_PORT_DOWN OR JOY_PORT_LEFT OR JOY_PORT_FIRE
would do the same thing in CBM Studio?

and #<(~JOY_PORT_FIRE)

Re: Joystick assembler routine
Thanks, I'll try to work through it.
Just out of interest, if this line
JOY_PORT_READ_MASK = JOY_PORT_UP|JOY_PORT_DOWN|JOY_PORT_LEFT|JOY_PORT_FIRE
defines a variable, what does it actually define?

Re: Joystick assembler routine
PS: It might be easier if you tell me which crossassembler you're using, and I can check it out myself.

Re: Joystick assembler routine
Thank you for your help! The FORTH implementation doesn't seem to offer me any help, unfortunately. Beamrider, your routine looks good, but there are bits in there which I and CBM prg Studio don't understand, subsequently it throws some errors. Would you be kind enough to let me know what various li...

Joystick assembler routine
Hello everybody, I'm trying to get into VIC-20 assembly programming and wanted to find a joystick routine. It's surprisingly diffcult to find one! Eventually I did find one on here: joy_dir = $F7 joy1 = $911F joy2 = $9120 LDA #$7F STA $9122 ;set DDR for input LDA joy1 AND #$3C STA joy_dir LDA joy2 A...

Re: Dig Dug PAL version
Ahh what a pity. It's a great convert, but it's running just that extra bit too fast to be enjoyable.

Dig Dug PAL version
Does anyone know where I can get a Dig Dug PAL version for the VIC from? I have the NTSC version, but on my PAL VIC it runs way too fast.

Looking for a particular game and app
Back in the days there was this game I was playing for the 40 columns mode. It was a kind of mining game where you had to dig for gems (I think) and at some stage water could fill the caverns. Obviously it was a text characters only game. The other app I'm looking for is a music composer that allowe...
