Denial

Cheers, also for the sourcecode to analyze and maybe even fix/improve the end-product even further

Is there a demand for this? It would be interesting to implement (as well as the PLOT command) but is anyone ever likely to make use of it? As a general rule: Do not expect people to ever use any tool you provide for an actual product, other than tinkering with it for the fun of it. While Mike and ...

I didn't actually mean hires-plot but just poking to the 40-column screen-RAM. So on a usually VIC-20 with 8K expansion you do POKE 4096,1 and an "A" is shown at the top left corner. You must have some shadow-screen-RAM for your 40 column-screen I suppose, so there should be a way to displ...

Of the original pack I think FAT-40 (aka VIC-40) is the best yet. It provides 40x25, emulates the PET-video-RAM at 32768 ($8000) so you can POKE directly to it and even emulates the PET sound-hack that was done through its user port and later supported by Commodore as well. Some time ago I "ocr...

TYA/STA $0300,X can be changed to STY $30,X

$0300 != $30

or in other words

page 3 != zeropage

There is news about this. Svolli made the hardware and produced a total of 8 officially licensed and numbered Boulder Dash-cartridges for sale. The 10 EUR licensing fee are a fact and in my opinion seem ok-ish for a cartridge-release. Mike and myself both got a cartridge for 60 EUR at the Revision-d...

So? What went wrong? Your code-snippet looked fine. And the STEP -1 command was fine as well.

Maybe the help-screen that pops up when you start cartconv without parameters should clarify this. RIght now it just says:

-l <addr> load address

while it could say:

-l <addr> load address (decimal, use 0x-prefix for hexadecimal, e.g. 0xc000)

Or just pop up a simple text-screen saying "Booting..." and maybe flashing the border to acknowledge to the user that the system is starting. For 2 seconds though this seems like overkill.

Is this the same as this? https://web.archive.org/web/20151028171029/https://vicpp.blogspot.com/p/this-is-test-page_8.html which has been discussed here? https://sleepingelephant.com/~sleeping/ipw-web/bulletin/bb/viewtopic.php?t=6835 Either way, I'd for sure like to test-drive this and maybe compare...

The first step should always be the S-Video mod. Most likely this will "fix" the issue.

The port looks and play very nice. Did you know about the version that was already finished in around 2021/2022 for the VIC_20? https://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t=10205 Check out the YouTube of the Preview as well: https://www.youtube.com/watch?v=1yhZ8Ty3bLo Unfortunate...

For what it's worth: I tried loading this .tap yesterday with my SD2IEC with TAP-support (from Manosoft.it SD2IEC ITS) on my original PAL-machine. Basically this emulates a tape-drive with the SD-card. It did not crash the computer, but did not start loading the second part either. I did the STOP/RE...

If you go to the monitor before the first and the second LOAD, you can see that somehow this procedure results in a stack pointer misalignment (first $f3, second $f2) I've played around with this a little and notice that the game loads fine, if you do a STOP/RESTORE before loading. This also change...
