Future-proofing the forum

I have noticed the forum being sluggish/slow the last few days and sometimes I even get a "429 Too Many Requests" error. I emailed joshuadenmark who is the admin and he mentioned needing to ask Jeff for login details. This got me thinking: Right now the forum seems to depend on quite some ...

Re: Boulder Dash Preview

Ulli just mentioned he put one of the cartridges for sale on Ebay:

https://www.ebay.de/itm/156955408571

Happy bidding. EU-shipping only as far as I see.

Re: Live Wire VIC-20 BBS

I was daring. Just your standard porn-crap. I'd say moderate the bad link away and all is fine.

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

Re: Beta Testers Needed

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 ...

Re: Beta Testers Needed

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...

Re: Beta Testers Needed

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...

Re: Conversion of VIC-SSS-MMX to CBM prg Studio

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

or in other words

page 3 != zeropage

Re: Boulder Dash Preview

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...

Re: Unclear bug in FOR loop (was: Bugs & Quirks in the [...] ROMs)

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

Re: BASIC Program on Cartridge

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)

Re: Max cartridge capacity

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.

Re: PAL CR VIC-20 With Dot Crawl & Ringing

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