Re: ** Revision 2025 Invitation / Website

Relating the number of releases to the number of people who handed in a release is a bit hard to do - since one individual can be involved in many compos (and often enough the same compo, using different handles...)

Re: ** Revision 2025 Invitation / Website

Likely, all people with remote or satellite tickets handed in at least one competition entry.
You'd be surprised. I'd count roughly half of them, which is probably still too much. There are quite some supporters who buy a remote ticket only to be able to vote (and to support the party of course)

Re: Assembler for the VIC

OK, with the passthrough this makes a lot of sense now. I'll proceed implementing it - however, the cartridge system in xvic is quite simple (compared to x64) right now, "cartridge with passthrough" can't be emulated like this. So this part has to wait for a while - too much other stuff on...

Re: Assembler for the VIC

OK so... looking at this now. Did i understand correctly: - the MON/CART switch essentially enables/disables the cartridge (which is mapped to IO2/3) - PGM enables writing to the cartridge (which obviously only works if there is static RAM or EEPROM in the socket) - Reset (short) is just that, a reg...

Re: WRITE NOW! cartridge image problem

I have added support for this now - please try r45649

I have also fixed (improved hopefully) the logic for mounting multiple raw binaries to the generic cartridge - would be nice if someone could test this a bit as well :)

Re: Boulder Dash Preview

Doing that would certainly be an excellent way to permanently ruin the chances of a continued cartridge production.
which is not planned, so there is nothing to "ruin"

Re: SVI-CAS Tape Emulation Units Available

It matters heaps when it comes to end product performance requirements. Hu? Are you confusing the Platform/API with some specific Microcontroller or Board? (Eg Arduino is available for the RP2040 and RP2350 - which has more than enough performance for this kind of thing. Actually it is hopelessly o...

Re: Assembler for the VIC

The firmware chip select logic works quite the same as Rabbit, yes, but the MINIMON cartridge hardware comes with some extras. Just had a closer look... could you elaborate a bit? I'm not really familiar with VIC20 hardware... and we don't have any freeze logic for VIC20 yet either :) Is there some...

Re: Atari Paddles on Commodore?

Amiga is kinda special, since the sample period is indeed locked to frames - and thus changes depending on the video mode

Re: BASIC Program on Cartridge

Using 0x instead of $ would have never crossed my mind - everything 6502-related always uses $ as hex notifier. You'd be surprised - most command line stuff supports (only) 0x notation - for exactly the same reason. And the few things that do not are a terrible annoyance once you try to eg use a ma...

Re: BASIC Program on Cartridge

Any chance to make the -l parameter also accept "$" as hex prefix instead of "0x"?
I'm not a friend of this - requires extra code AND it is annoying to use on anything but windows.

And yes, load address really only matters for the generic cartridge type

I know what Arduino is :) I just don't see how it matters - at all.

Re: SVI-CAS Tape Emulation Units Available

How does the platform/api used to program it matter anyway? :)
