Re: Boulder Dash Preview
For the record, the eBay auction went for 65,99 € + P&P . Why does [it need] 32 KB [...]? The cartridge contains a 6264 (8Kx8) SRAM - as scratchpad, workspace; for decompressed level data; you name it - and a 28C256 (32Kx8) hardware write protected EEPROM, the latter of which 24 KB are used for ...

Re: Beta Testers Needed
For the sheer fun of it, I tried out MINIMON in FAST-40: https://dateipfa.de/.Public/denial/images/minimon/MINIMON_in_FAST-40.00.png It works! :mrgreen: Moving the cursor back into the disassembly or into the hex dump does as supposed and lets the user change code or hex data. When MINIMON has been ...

Re: Re-assembling ROM Disassembly
I do have a copy of the Vic ROM Disassembly book [...] This happens to be the one by Peter Gerrard and Kevin Bergin? The ROM 'disassembly' in that book not only does not feature any commentary - they disassembled data tables as machine code , even put an half-hearted excuse about that in the prefac...

Re: A sample debugging session with MINIMON
In conjunction with a stub cartridge , MINIMON can provide STOP/RESET functionality similar to C16/C116/+4. This allows to recover from a CPU crash, yet retains most of the zero page contents. I/O (screen and keyboard) is re-initialised and instead of showing the normal BASIC start-up message, you g...

Re: A sample debugging session with MINIMON
From the thread " Stack Watching in VICE ": [...] how does MINIMON handle an RTS during execution, then? What return address gets pulled? Most likely, $E144 - 1 of the SYS command used to invoke MINIMON. BASIC then continues with whatever it finds in the input area behind the position of t...

Re: Live Wire VIC-20 BBS
So, then, is there anything about the link that requires more than at least moving the thread out of immediate view for the public?
I do not have an heightened interest to also click the link and be presented with unpleasant things.

Re: ** Revision 2025 Invitation / Website
There are quite some supporters who buy a remote ticket only to be able to vote (and to support the party of course) Those are of course another two good reasons to buy a ticket (regardless whether at site, remote or at a satellite). :) The exact number of handed-in entries remains elusive though, ...

As a final roundup: from the "Who's here" page on Partynet, Revision 2025 had 878 official participants (i.e. people who paid for a ticket in whatever form), of whom 139 people were remote attendees (i.e. off-site and not organized in a satellite event), 49 people were satellite attendees ...

Re: Assembler for the VIC
- the MON/CART switch essentially enables/disables the cartridge (which is mapped to IO2/3) In essence, yes. There's circuitry on the cartridge, which arbitrates the I/Ox signals between the ZIF socket and the secondary cartridge. The reset logic is available all the time. - PGM enables writing to ...

Re: VIC-20 modified Kernal
In addition to the effort required, and apart from faster disk routines as exemplified by JiffyDOS, what sort of thing would be best done in a kernal as opposed to a cart or disk program? If I understand correctly, the kernal is a fixed standard library or API that any software might rely on. The K...

Re: Port of BBC/Electron Boulder Dash
The posts about the officially licenced version of Boulder Dash have been split off and merged into the thread Boulder Dash Preview.
Any discussion about that version and about the cartridge release should go over there. Thanks.

Re: Boulder Dash Preview
Good point! I split off the part in the original thread beginning with the (slightly misplaced) post of mrr19121970 dated from Sat Apr 19, 2025 and merged that part with the thread here.
Posts regarding the BBC port of Boulder Dash still should go there.
