Re: A couple of games in BASIC I worked on recently.
Nice. I did not go too crazy on the optimising of the 2k one.. just enough to keep it within the 2k. Ideally I didn't want it to become a complete unreadable mess.

A couple of games in BASIC I worked on recently.
Some people on a discord channel I am on decided to have a go at writing some very small retro games in BASIC. First off we decided to go with seeing what we could do in 1K. After I attempted that we agreed that 1K was probably a bit too limiting so we decided to go with 2K. I decided BBC basic was ...

Re: Citadel Disassembly / Reassembly v0.1
Brilliant work. This was probably my favourite game on my Acorn Electron

Re: Electron Dunjunz
I did a write up here of how the disc version was done for anyone with some understanding of 6502 who wants to see how it was made

Re: Electron Dunjunz
Have a go with this... I have only tested it on Electrem and Elkulator and not on real hardware. it works on both of those using E00 DFS. Hopefully will work on real hardware too. I did have to use some bytes at the bottom of the stack space as a temporary store which is a bit risky, i only got as f...

out of interest what does 'do everything after load yourself' comprise of in order to load data without going through the standard *LOAD routines?

Re: Memory-efficient decompression for embedded computers
I have attached some stuff I wrote earlier this year when doing a tape 2 disc conversion project for the Electron. It is a lzss compressor in C# (source code included) with a 6502 uncompressor with BBC basic source code included. The source code includes a test project that compares several slightly...

Re: A new conversion for the BBC Micro
We got some coverage of my release in the latest retro gamer magazine where they gave us a review score of 91%, Thanks to kieranhjfor suggesting putting this forward to retro gamer. Also thanks to retro gamer magazine for the review. I did also do a developer interview for them but not sure if that ...

Re: A new conversion for the BBC Micro
That's super smooth - good work Darren, thanks for sharing, nice to see the source available too! :) Do you have any other Beeb conversions in mind? I've just bought an Amiga 1200 so I have a plan to go back to some of my old Amiga sourecode and possibly finish off some tools I started writing in 6...

Re: A new conversion for the BBC Micro
It happens on both sounds, falling and jumping. Not always, but at least 50% chance with both sound effects. This morning the game did not produce any sound at all, I'll try to replicate that somewhere this week. When you have some time can you give this one a try on the real hardware https://dmcol...

Re: A new conversion for the BBC Micro
Wow, nice and smooth! Made it to level C... On my real model B it has an issue with the sounds though, sometimes the sound is "hanging" so you basically have a long beeeeeb while playing until another sound is produced (hope this makes sense). Thanks for the feedback. I heard another report of the ...

A new conversion for the BBC Micro
I am very proud to present to you today, my latest project that has been in progress for the last few months. I decided to put together a conversion of the game Trailblazer https://en.wikipedia.org/wiki/Trailblazer_(video_game) to the BBC Micro. I chose this particular game as I have pretty much zer...

Hello from long time lurker
Hi. I've been aware of and occasional lurker in this forum for quite a while. I registered so I could post on one particular topic but since I have now registered, i figure I should introduce myself. The Acorn Electron was my first computer back in '86 for my 13th Birthday. I learnt to program that ...

Re: The BBC Micro In Pixels
I've got all 3 of the ZX Spectrum in pixels books (as well as quite a few other similar retro related books). It had occurred to me that the Acorn machines seem to be notably missing in the flurry of retro computer books that seem to be around at the moment. The only book i've managed to find that i...

Re: I know I've asked this before a thousands times BUT...
It's good enough for me, although actually most people do prefer DFS versions as the system keeps PAGE at &E00. Actually, with all that extra memory to play with, you might be able to get the DFS version to work without the score quirks... Or someone else might be able to have a go... :-) the 31 fi...
