Disassemblies of BBC Micro Games

[MarkMoxon]

Not sure if this makes the list (I won't be offended if it doesn't!), but I've done a fully documented reassembly of Lander on the Archimedes. Of course, the A305 and A310 were BBC-branded micros, so technically this is a "BBC Micro Game", and as this isn't an 8-bit section of the forum and there doesn't appear to be a 32-bit disassembly thread, I thought I'd offer it up...

Anyway, website here:

https://lander.bbcelite.com/

and buildable source here:

and also posted to its own thread here:

Do with this information what you will!

Done - I've added an Archimedes section.

Thank you!

Made a start on Bruce Lee last night

Main code is Bruce1.asm, loads at $1900 and relocates down to $0900 and also another small relocator down to $0386

NB BLOAD basic program is corrupted as it uses embedded control characters, but the game compiles and plays fine.

Thanks, added. I look forward to seeing how this progresses.

Oooh, still thinking about recolouring it?

I've disassembled Boulder Dash (1988).

Would be nice to also change sprites as well as the colours

Very nice

When I get a spare 20 mins I plod away at Bruce Lee, never knew it has so many JMP tables, as they’re a pain in the arse to decode.

You've made a good start.

I notice Level7 has done one of my favourite games from BITD, Elixir. I really loved this game as it's a hybrid sprites and 2D vector graphic game that was rather like a load of things I later coded in Flash 2 when I used to do Flash games.

I always wondered how it worked. I'm going to really enjoy going through this disassembly.

Many thanks Level 7, whoever you are!

Added, thanks.

Question on disassembling a file that contains both basic and 6502 code, how would you go about dissembling it so that it can be recompiled back to the same code, say for example superiors hunchback

Can beebdis and beebasm handle a mixture of languages?

[bob147]

I'm no programming expert but I did help test @Stevef's Night-World disassembly and that is a mix of BASIC and assembler (which would imply py8dis and beebasm can handle that scenario at least!)

[fizgog]

Thanks for that, I did wonder if it was best to extract it out and then add it back in

[tricky]

Bevan can tokenize basic, but you have to get a little more creative to mix them, although I do

My neighbour’s 4-year-old is getting quite good at Super Invaders. Perhaps a bit young to start him on assembly language programming, though.

Level 7 has disassembled Stryker's Run (1986) - both standard and enhanced editions. The enhanced edition has lots more sprites, a high score table and two tunes.
