Daredevil Dennis Tribute

Thumbnail

• Upvotes

A while back I was writing a blog about the first game I'd every designed and built for myself on the BBC Micro and in the blog I wrote 'it was no Daredevil Denis but I was proud of it'. That got me thinking and after contacting Simon Pick and getting his OK, I wrote a mobile tribute game to Daredevil Denis called Daredevil Dennis Rebooted.

Rather than just create a port I wanted to take the essence of the game and make it work on mobile (I didn't think the 3 layers would work so well). It is now live in both the Apple and Google app stores, it is free to play, ad free and collects no data.

It comes in two modes, a modern version of the game and a retro mode that looks as close as I could get to the original MODE 2 look.

I'd be interested if anyone has done anything similar for other Beeb classics , I'd be interested in a re-imagined Frak, Chuckie Egg or Jeremy Goes Jumping :-)

BBC Micro "Next"

25 Upvotes

I'm sat here looking at my Spectrum Next, waiting for the issue 3 board that apparently will let me load a BBC Micro core. I've just read about the new Plaion Atari 800XL that's available for preorder, and I'm kind of wishing that some brave soul would launch a BBC Micro "Next". Bonus points if it lets me hook up a Music 500, but I'm not holding out hope for that. Anyone else wish there was a reissue?

I built MacOS Beeb Emulator - with second processors

69 Upvotes

For exactly no reasons other than "could it?" I spent an afternoon playing with Claude Code to see if it could build me a Beeb emulator. And I'm very happy with the results. I've now got an emulator that runs really nicely (so much so that I can dock in Elite without a docking computer), emulates a 'B' or Master 128, with 6502 or Z80 coprocessors, that will run CP/M.

IIf anyone wants to play with it I pushed it to Github. Enjoy!

Anyone have any of the old manuals for this competitor of EcoNet?

Back in the 80s, I discovered 3 hacks for this system at my high school on the Isle of Wight (and a neighbouring high school).

Would love to go down memory lane.

VIEW decompilation and C port

Post image
47 Upvotes

I've just finished (== stopped looking for new bugs) a machine-assisted reverse engineering and decompilation project of the VIEW word processor, producing both an extensively symbolised disassembly but also a portable C version which will run on Unix-ishes (and should be easy to port to other platforms).

The result is about 10kloc, producing a 48kB binary on amd64. It supports most features except for printing (and printer drivers, the hooks are in place internally but there's no way to load drivers. dlopen() would help here if anyone cares enough). The source code quality is... fine; the original was written in hand-tooled machine code with spaghetti code structure, which doesn't map onto C flow control very well, meaning there are still a lot of gotos around but it's mostly comprehensible. The keymap has been reworked to be WordStar-like due to the inexcusable absence of an f0 key on modern computers.

I have no idea if this will be at all useful to anyone, especially given the license situation, but VIEW is a perfectly cromulent word processor which never got the love it deserved at the time, and maybe these would be a good candidate to run on microcontroller writerdecks or similar. Or maybe there are people who just want to use VIEW in the modern world, in which case this is for you, except don't use it for valuable data because I'm sure there are bugs.

See https://github.com/davidgiven/view for the source code.

Pasting via OS in b-em into Acornsoft forth to fill your buffers

9 Upvotes

That line editor is a bit difficult, so I wrote this python to produce a file to copy paste into an emulator to fill a .ssd. Enjoy the bootstrap productivity gain. :D

```

!/usr/bin/env python3

import sys import textwrap

WIDTH = 64 LINES_PER_SCREEN = 16 EDITOR_WORD = "P"

def usage(): print(f"Usage: {sys.argv[0]} INPUT OUTPUT FIRST_SCREEN") sys.exit(1)

if len(sys.argv) != 4: usage()

input_file = sys.argv[1] output_file = sys.argv[2]

try: first_screen = int(sys.argv[3]) except ValueError: print("FIRST_SCREEN must be a number") sys.exit(1)

Read source, preserving blank lines.

with open(input_file, "r", encoding="utf-8") as f: source_lines = f.read().splitlines()

Word-wrap each source line to WIDTH characters without splitting words.

wrapped = []

for line in source_lines: if not line.strip(): wrapped.append("") continue

wrapped.extend(
    textwrap.wrap(
        line,
        width=WIDTH,
        break_long_words=False,
        break_on_hyphens=False,
    )
)

Write numbered editor lines, 16 lines per screen.

with open(output_file, "w", encoding="utf-8") as f: screen = first_screen line_number = 0 f.write(f"EDITOR {screen} LIST\n")

for line in wrapped:
    f.write(f"{line_number} {EDITOR_WORD} {line}\n")

    line_number += 1

    if line_number == LINES_PER_SCREEN - 1:
        screen += 1
        line_number = 0
        f.write(f"{LINES_PER_SCREEN - 1} P -->\n{screen} LIST\n")

# No extra screen marker is required; the screen number is implicit
# from the number of groups pasted/entered.
# clear last continuation maybe and save all.
f.write(f"{screen - 1} LIST {LINES_PER_SCREEN - 1} P \n")
f.write(f"FLUSH FORTH\n")

```

Rogue Tank - A BBC Micro Homage

26 Upvotes

I made a game as an homage to the BBC Micro, the 8-Bit home computer which was popular in the 80's (but not as popular as the Spectrum or Commodore machines).

I liked the idea of making a game using GDevelop which had some of the aesthetic constraints of the BBC Micro. Specifically the colour palette and resolution. This is my first GDevelop game, and was using it as a learning exercise. All feedback welcome (touch support not (yet) enabled)

Paradroid port to the BBC Micro

28 Upvotes

Hey all, I finished my port of Paradroid from the C64 to the BBC Micro. You can download the disk, play it online in the jsbeeb emulator, or read through the source code here: https://bitshifters.github.io/posts/prods/bs-paradroid.html

It was a lot of fun to revisit the game and work through all of the technical issues, particularly as the Beeb doesn't have smooth scrolling, hardware sprites or a character mapped display. Consequently it requires 64K of sideways RAM, so works natively on a Master but also compatible with Model B/B+ if you have sufficient RAM. Let me know what you think!

[Disclaimer: AI assisted with Claude Code.]

Um? Well, I started on a personal disk set at 400.

I have it on *DIN400, then shift+break. I'm making my own mini menus (in basic). Also setting up a build edit cycle via some linux bash scripts, and basictool, MMBExplorer, dfsimage and nano.

I've only found out rough details of the *MENU system on the .mmb, like xx-xx-0 have !BOOT files. And likely disks with non-standard formats can appear "not present but titled". Also being *MENU I can confirm ADT-2.0 ROM has a *MENU command name collision.

Lots of the "game" disks do have "free" space on, but in the spirit of sector reading of old "data" with no catalog index, for say "protection", using it might have varying results. Makes you wonder what's on disk 16.

AcornSoft games source code

48 Upvotes

I've been playing around with old BBC Micro stuff recently. I've created a browser environment for writing and testing BBC 6502 programs.

This came about because I wanted to decompile some well-known old BBC Micro games (including my own, for which I have lost the source code).

I wanted it to be simple - "assemble then run" - So the time between compile and run code was just a few seconds.

If you're interested you can get an idea of how to use it by looking at a video I made of a typical session:- https://tobybuk.github.io/BBCMicro_6502WebCompiler/SampleSession.mov

The Workbench can be found here which is open source and fully useable :- https://tobybuk.github.io/BBCMicro_6502WebCompiler/

And a detailed Readme.md here together with the source code:- https://github.com/tobybuk/BBCMicro_6502WebCompiler

I had lots of fun building this with ChatGPT

Annotated source for Defender, Frak, Zalaga, RocketRaid and Snapper is all there.

Just compile and run. Then have fun changing stuff.

Edit: Youtube alternate link for the Video https://youtu.be/2j2Wodx0jSQ

Please let me know if you also get any 404s

New Android BBC Micro emulator

38 Upvotes

Hi Reddit,

I spent ages trying to get Beebdroid to work on a new Android device, and never managed. I also tried the various dead-ends kicking about on the web (Sleakweasel's version etc...)

Ultimately, I ended up converting Mike Wyatt's BeebEm to run on Modern Android devices - e.g. The latest Samsung's and Pixels.

So if anyone is interested in playing BBC Games on their phone, then the emulator is available at https://github.com/Isomage73/BeebEm-for-Android with an APK that you can install yourself (if you're happy to trust unknown sources.)

Here's a video of the UI with gamepicker

https://youtu.be/gpt_r8pzluQ?si=ZRCkFuKnPF0DelWS

Hope someone (other than me) finds it useful :)

Quest for BBC Micro Decompiled

This game was such a mystery as an 8 year old so I could never make any progress, it was time to revisit with and reveal all its secrets.

https://github.com/retro-foundry/quest-decomp

The source should be easy to edit, let me know. I'll make a fork which fixes soft locks, the reactor bug and probably give Walter a gun at some point.

I luckily managed to save this master 128 and lots of accessories from the skip

My dad's childhood friend was in the process of clearing out his mum's house. I managed to ask him to keep anything vintage from going in the skip and I would look after and fix anything he gave me. Unfortunately it was too late for an IBM, electron and a BBC micro. Unfortunately he had thrown out some crt TVs too.

There were quite a lot of items that came with it. Every magazine for the electron from number 1 to the last. Lots of books and disc games. It's an incredible collection for it. I'm glad I managed to save this from the skip too.

I'm completely new to 80s computers, apart from dabbling with my commodore 64 I don't really know what I'm doing or what some of this is for. Especially the chips and ROM expansions. I have been working with the disc drive, but unfortunately I can't get it to load games. I can get it to load the contents, but discs won't load after, so it's still a work in progress. It does play tapes very well though and is a fun thing to mess about with.

These are the things i need to know

  1. How much is a BBC Micro? (willing to spend no more then £175-200)

  2. What is the best BBC Micro?

  3. Is BBC BASIC easy to learn for a neurodivergent person to learn?

  4. Is the BBC Micro just a keyboard you plug into your tv?

Please help me understand this!

ps. I was also looking at a BBC Bridge Comapanion but it didnt sound too intersting after i dug further into it

Problems playing Elite on Turbo MMFS

10 Upvotes

Can anyone point me at a decent guide to playing Elite on a Turbo MMFS SD card setup. I tried with the standard one on the BeebM Image that has "all the games" on and it fails.

Thee issues is I get "bad command" when I dock to the space station.

I have tried a few other images and get the same issue, the Compendium looked promising but I don't have Sideways Ram. Playing the Elite Compendium - Elite on the 6502

Has anyone got a reliable image and set of instructions on how to do it? Im sure its something silly like disk mounting or something.

A program like Wordwise but supported rich Teletext colour and graphics?

9 Upvotes

This is out of curiosity more than anything.

I'm looking for a program from back in the day when I ran a bulletin board system (LBBS).

I had a rich text editor that behaved and looked just like Wordwise but it allowed you to change the text colours and use rich full Teletext (background colours, flashing text etc) to create rich colourful documents.

Does anyone know anything about the program I'm referring to?

You can play and read about it over here: https://bbcexile.com

Added some QoL features to the conversion (like quick save which oh my goodness helps a lot) and a widescreen mode (that had some interesting ramifications).

Plugging away through the deep dives. Mostly written, just editing and slowly publishing them as life and time allows.
