I suppose you're referring to the menu option 'Snapshot > Save/stop media file ...' in VICE. In that case, this has nothing to do with your graphics adapter card. VICE always saves the screen buffer contents before any filters (such as rescaling and TV system emulation) are applied. And this screen ...

The low-byte of the jiffy clock is counted up by 1 every 1/60 second, and wraps from 255 to 0. That means, on entry to this sub-routine the byte is either in the range of 0 to 59, and then the routine waits the remaining time until the byte becomes 60 (which already is not constant), or the byte has...

I just tried the SPLASH file from your Spidey vs. Doc Ock game. It loads fine without issues. Most of the white colour 'background' is actually drawn from foreground colour, with multi-colour enabled. These cells change to display vertical stripes in hires mode. So far, expected behaviour. If this i...

It is most probably an attribute cell with multi-colour data that changed into hires when you overtyped it with a character. As I wrote in the OP, the attribute cells are tiles of 8x16 (hires) pixels, i.e. the area of 2x2 (small) characters is always affected when the colour RAM needs to be changed....

Ghislain got the Comet64 to work on the VIC-20 in general with a suite of programs detailed in the thread ' Internet Connectivity with Comet64+VIC-20? (IT WORKS!!!) '. Three years ago, there had been a demonstration of a VIC-20 posting on Twitter that even got broadcast coverage. See the thread ' VI...

Just a small remark about this section: [...] lda $10fe sta $900e [...] The original code in MINIGRAFIK and in its executable pictures does a slightly more elaborate: LDA $900E AND #$0F ORA $10FE STA $900E MINIGRAFIK saves the contents of VIC register $900E (auxiliary colour and volume) with the bot...

Unless your VIC-20 has been modded to output S-Video, you'd only have to connect composite video (yellow cord) and audio (white cord) to your TV set. Please check that the yellow cord connects to pin 4 of your DIN plug and that the white cord connects to pin 3. Here's how they are arranged when you ...

This is a - small - issue I have with the demoscene in general. One of several - small - issues indeed. But I am not going to argue here. Either way: I will be attending the party and have this run on my VIC+Mega Cart. Whoever wants to see it/try it out is invited - don't forget to bring beer ;-) T...

No, you're mixing up expressions and statements. To clarify, most (imperative) programming languages make a difference between statements and expressions : A statement is some instruction or command which is intended to be executed by the language, e.g. PRINT, GOTO. In that sense, the LET statement ...

This statement is not interpreted as double assignment in BASIC V2, rather the result of the Boolean expression ST=0 (either -1 if true, or 0 if false) is assigned to P.Witzo wrote:How does this work?Code: Select all
