Re: "Unfixable bug" in BBC B Elite

I stumbled across this video by David B, a postmortem of Elite. http://www.gdcvault.com/play/1014628/Classic-Game-Postmortem It's worth a watch Lots of classic Braben fabrication there, I'm afraid. Anyone with a copy of Acornsoft Elite can disprove two of the claims themselves. 1) On the change to ...

Re: "Unfixable bug" in BBC B Elite

BBC B Elite, which must be considered to eventually have been completed because there was literally no more RAM in which to fix the single remaining known bug: IIRC, it needed three bytes, and after many sweeps through the code, optimizing each time, there was no more fat to be wrung out of it. Tha...

Re: Music 5000 FPGA

I gather it must be one of the defacto standards I'd not heard of it being used prior to the Music 500. Which is not to say no such usage existed. If anyone finds record of one, I'd be interested to hear. since I've seen Acorn use it with VIDC Acorn copied it from the Music 500 circuit. You may rec...

Re: Music 5000 FPGA

My understanding is that, when the modulate bit is set in the control byte for channel N, the sign bit of the generated waveform governs whether the primary or secondary parameter set is used for channel N+1 (or +2, from what Chris said?). Is that right? That's correct. The modulation by channel n ...

Re: Music 5000 FPGA

ChrisJJ, I'd really appreciate you looking over this and seeing if there is anything that seems incorrect, or that I have missed. The bit I was least sure about is the operation of the frequency modulation. Sorry not to have seen this at the time. My feeback is now at https://github.com/hoglet67/Mu...

DFS Imager

Anyone know where I can get a version later than the 14.02.06 I received with the BBC MMC card?

Or another workaround (on PC) for this version's disallowance of full-length DFS disc titles? It stops at 11 chars, which I assume is a bug, hopefully fixed.

Thanks.
