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...

Re: Colour blue on NTSC VICs.
> Just checked. Green looks like Cyan on my VICE as well. That is only with the internal palette, however. If you choose "Mike (NTSC)" as external palette in Settings-Display-VIC-VIC palette it looks more like green, and this palette was derived my Mike from the results from my personal NT...

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

Re: VICE key-rollover inconsistencies
I have implemented (partial) emulation of the Keyboard matrix quirks some years ago - indeed only for C64 (and C128 i believe). Even for those, it doesn't really work right in all cases (but good enough for 3 keys i think). It's quite a surprisingly complex problem unfortunately :) So no, you are no...

Re: Making a cheap Power supply.
VIC20, yesIt'll work - mostly - if you don't connect anything at all to the 9VAC pins. That voltage is used on the user port for things like RS232 and some modems, and also for the datasette motor.

rhialto made a quick patch

Re: Stack Watching in VICE
BTW, i am offering a crate of beer to whoever implements a "dereference" operator for the conditions (so you can use the content of the memory whatever expression points to) - that would be super useful indeed

Re: Stack Watching in VICE
I don't think this can be done directly (please correct me if i am missing something) - you can only compare registers and memory locations, there is no way to tell "was pulled from stack". Perhaps you can do something like ($100+SP)=$55 && A=$55 (which is obviously not really what...

Re: C=Hacking Issue 8 - fast plot routine with 20 cycles
Next step would be unrolling the loop for each needed slope... perhaps not on VIC20 though

Re: Crazy Cavey
Raster tricks are actually easier than on VICII - since there are no "bad lines". Very straight forward
