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"

Maybe not everybody is aware that now there's two versions of Boulder Dash [...]

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.

I was quoting Ullis words.

That is not at all recognizable from your earlier post. Anyhow it is a kind of statement I would only rely on if I had got it from the person themselves.

Would be nice to get a ROM dump of this......

On that picture I can see a 8kB RAM chip, as well as an EPROM.
I don't know any other cartridge that has an RAM and ROM chip on board, apart from the Super Expander, which adds 3kB.
I think the ROM can only be 8kB large. So the game only needs 8+3.5kB of RAM? Why does the Youtube video say the disk version needs 32kB RAM then?

[Mike]

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 the game, so there ...

Interesting! That is still unusual, isn't it? I'm not aware of any other cartridge using that kind of setup.

Did the author of the other Boulder Dash version simply ignore potential licensing issues?
