Re: SD2IEC DIN plug color codes

I'd be very careful about associating colors with whatever here. It could be completely random and different in the next device. There is no standard for this, and everyone can build the thing however he wants.

Re: Bi-Directional User Port Code

Not for VIC20 - but the "PC64" userport cable (for the C64) worked like this, ie bidirectional, 4bit per direction. I don't know if this was ever adapted to the VIC20 - but there is quite some code around for it that you could look at. Eg the "over5" utility supports it

Re: Would a VIC-20 Denial code snippet repository on Github be welcome?

Because one cannot build anything in a Wiki and you can't take it to places with no Internet could be cons.
Not sure what you are trying to say, but "code snippets" cant be "built" anyway. And "no internet" seems more of a theoretical than a practical limit to me. YMMV.

Re: Would a VIC-20 Denial code snippet repository on Github be welcome?

Why not use a wiki (like codebase for c64) instead? Works better for such things, IMHO

Re: Colour blue on NTSC VICs.

If needed I can do a new capture - in theory I could also measure the phase offset between light and dark colors with my oscilloscope, although how exactly I haven't yet found out. If you could talk that Tobias guy on F64 to do the same analysis for the NTSC colors that he did for the PAL colors, t...

Re: File Command Errors

Yes, macOS requires binary signing, which we can not do automatically. (You can use homebrew to install the svn-head revision though)

Re: Colour blue on NTSC VICs.

The 'normal' colors (2-8) have a phase error on NTSC compared to their lighter variations (9-15) - this is due to how the color signal is generated on the chip. Can you quantify that phase error? I am experimenting a bit now... i added 30 degrees to colors 0-8, the result seems close to your captur...

Re: File Command Errors

Awesome, I appreciate that! I'm not sure what the build process is for VICE, so I'll probably have to wait for it to trickle into the released binaries, but I wish SD2IEC was so responsive! You can always grab development builds from here: https://github.com/VICE-Team/svn-mirror/releases - they wil...

The wrong behaviour in VICE when a host directory is mounted via vdrive. Scratch reports one file scratched now, and the rename command reports file exists as it should.

Re: Colour blue on NTSC VICs.

No problem at all here, with xvic -default

(No need to actually delete vice.ini, starting with -default does the same)

Edit: Just realized i was missing NTSC - i also see green turned into cyan now. No idea if that is just how it is?

Re: Colour blue on NTSC VICs.

Link to the PRG?

There might be a problem with limiting the values in the CRT emulation, so something overflows.

Re: VICE key-rollover inconsistencies

It's basically a matrix of 8x8 resistors, 8 current sources, 8 current sinks (and all of them programmable as either source or sink) - not trivial at all :)
