Thanks, didn't realise you could do that. It's fixed the issue on 3 of them

Certain games left shifted on screen
I've got a VIC-20 PAL Version connected to a LCD monitor via a RetroTink 2X Pro. This has been working well and have no issues using my VIC. I'm now trying to create a cart with a few 8k games on which is selectable via dip switches. I'm noticing a few games are left shifted off the screen. Most of ...

Re: Faulty RAM - interpreting diag cart.
Code is here, hopefully I'll get to finish it off sometime https://eden.mose.org.uk/gitweb/?p=dead-test.git;a=summary After tinkering around for a few days and pulling my hair out, I finally wrapped my head around most of the code. Still some of it is over my head but I managed to cobble together s...

Re: Simple assembly program issues
Lovely stuff. That did the trick.
Thanks for the quick reply. Didn't even occur to me to init this space...or that VICE sets it to all 0.
I've got a pal/ntsc routine. First thing I found out how to do. Just excluded it in case it was the cause of the issue.

Simple assembly program issues
Trying my hand at some assembly for the Vic 20 and so far I thought it was going ok but have run into a strange issue. I've got a simple program that prints out TEST on the upper left. This runs from a cartridge at A000 and I've been testing it using VICE. The weird thing is it loads fine in VICE, a...

Re: Faulty RAM - interpreting diag cart.
Lovely. Thanks very much.
I've started tinkering around with Visual Studio Code and ACME + VICE. Boy have I forgotten a lot of asm in the last 30 years
Will let you know if I make any useful changes to the code.

Re: VICE. Unable to get IEC working with xvic
Yessss!!! That did it. Thanks a million.
I must have had I enabled for the C64 but not the Vic.
Now enabled and works as expected with:
TDE disabled
Drive type: 1541
IEC (OpenCBM) disabled
Device type: File system

Re: VICE. Unable to get IEC working with xvic
Thanks for the explanation. I clearly have no idea how it works :) With TDE it seems to ignore this setting so I thought as it was enabled on the C64 and it worked, then it was needed. So now this is really driving me mental. It just refuses to work for the Vic 20. I've run some comparisons between ...

Re: VICE. Unable to get IEC working with xvic
i'm trying to load/save programs using IEC (OpenCBM), not a physical disk.
With dos1540 selected and IEC ticked I can list, load, save files on the local file system using x64 for the C64.
This does not work for the Vic 20 so I'm unable to load/save files locally.

Re: Faulty RAM - interpreting diag cart.
I'm running this from a cartridge with no memory expansion. Results are repeatable to looks like UE4 is the issue then.
At least this narrows it down. I'll replace UE4 and see what happens.
Let m know if you publish to git or something.
Thanks again.

Faulty RAM - interpreting diag cart.
I bought a faulty VIC20 (324003) off eBay that's had a hard life. Replaced the kernal and char rom's with 27c64's with a conversion board which brought it back to life. At least its now booting up and screen looks fine. Amazingly the VIC and CPU are fine, it starts up and see's 3583 bytes. When I ru...

Re: Building Ruud's 35k RAM expansion
Cool, will give it a bash.
Can now start messing around with my Vic. Bringing back memories from 30 years ago typing in pages and pages of code from magazines
