Re: Jalapeno 2nd place

Oh! That means even though the underlying mode uses 8x16 attribute cells, one can have dynamic updates of the colour RAM, even if those updates are a comparatively scarce resource. Nice! Yes, exactly! Quite expensive to do each write but it’s possible to have 8*1 color cells in local areas of the i...

Re: Jalapeno 2nd place

It's constructed from two images, a background color image and a foreground color image. Using those two, flexible assembler code is generated to set cycle exact background, border, auxillary and character colors in order to achieve the same result on the VIC20. So any of the available colors can be...

There’s no music on NTSC machines due to lack of CPU cycles.

Re: VIC 20 Apollo DSKY Indicator Lights

It might be easier to flash by changing the colors of the characters instead.

Re: Page boundary crossed, CBM Studio

That setting will give a lot of false positives in a large program. This needs to be applied only in the places where it is useful. Maybe there’s a way to turn it on and off during assembly? I wrote a macro to give me that warning if a block of code crosses a boundary instead.

It can hardly get more simple than that. We have a winner!

Re: Ternary or if/else in BASIC

It was a long time ago I programmed BASIC V2 so take this with a grain of salt. And I didn’t test this so I may have made an mistake. The comparison results in either -1 or 0 so this can be used mathematically to set values. It can be neat sometimes but is probably not the most efficient solution. V...

Re: IEC serial output bits

From a quick peek into the *.d64 I'd assume the text body is compressed and you use some IFFL-like technique for quick seek into the files? The proportional font rendering engine is also quite nice. Any chance you show it here in the Programming section for discussion? Similar to IFFL, I'm having c...

Re: IEC serial output bits

Yesterday this was released to the public. Not that useful if you aren't speaking Swedish though.
