Found a zip of an assembler I wrote back in the day with Ian. I prepared this zip in 2011, so I may have released it before. It can do (some) macros and AOF and was a load faster than Acorns (which was important when I was working on an A3000).

Attached is a zipped arcfs archive.

I have a disk of my licensed version ExtASM that I keep meaning to copy and post up.

I'm disappointed you didn't suggest your own ScriptAss

That's cos only thee and me have ever really used it.

There's some interesting puzzles; but it shows that it was an early adventure. It is definitely the weakest of the Robico adventures.

I found I'd done 90% of the work 2 years ago, but hadn't got my transformation matrix maths right. It was quite easy once you translate Draw units; most objects translate directly from Draw to SVG, maybe with some minor conversion (such as origin being top left and the transformation matrix being at...

I have 80% disassembled this game: https://tautology.org.uk/blog/2017/11/01/reversing-robicos-island-of-xaan/ With my in-depth notes and some pseudo Python of some of the game logic at https://github.com/tautology0/textadventurestuff/tree/master/Robico/xaan It is silly, but I think I did the disasse...

I've updated my draw2svg convertor so it now manages images and transforms (after stealing^W borrowing code). There are some bugs in sprites and transforms, but it's quite nice to convert some of my 30 year old draw files onto a modern system.

I wrote a draw2svg converter a while back (in https://github.com/tautology0/dataconverters). It doesn't do transform or sprites (I was going to steal^W borrow your sprite to png converter, but never got around to it). I've messed around with David Boddie's Impression stuff in the past, but never act...

Mostly I want a text editor for plain text files. I know View files are more or less plain text, how about WW and Interword though? I've done some partial decoding on these formats, View is the closest to pure text, followed by WW+. Interword is weird and wonderful. I did a very basic Iword reader ...

I used to use DIS6502 with some defined equates that were BBC specific. But, as it was a pain to save properly I used to export to a large text file and then BeebASM it manually. Now I've moved to Ghidra, as I use it in work for doing reverse engineering. There's some bugs with the disassembly (e.g....

Man at Arms and Pysanki were graphical adventures not text adventures. Sorry.

Forgot to note, it's tokenised BASIC, which is not a surprise. So we're missing the program totally - these are just the DATA statements at the end.

Good find!

I don't recognise it, but here are the strings: y a cruise missile!" 41,far stairway,"You enter onto the far staircase." 29,dinner hall,"You go into the sixth form dinner hall.There are sixth formers everywhere.Most of them are eating their dinner." 30,common room,"You ...

Can I have an invite too? I'll probably just lurk though.

So you can drop most of the word wrap by moving TEXTCOL to 39. There is a bug where the string starts with a CR character and it seems to do an LF instead, which I'm not certain why as it should pass it to OSASCI. I may need yet another rewrite of the word wrap. What I may do is just bite the bullet...

Just as an aside to this, is it possible to get an Electron version (i.e. Mode 6), as the Elk version had the same bug?

A very quick version - there is still a bit of a bug where it introduces a character code before some room descriptions:

Thanks for getting it on bbcmicro! I'm still tempted to add graphics to it (either MODE 4 or MODE5/4 split screen). In terms of building a new game it's a bit of a pain, but easier than it once was. Step 1, prepare the data file. As the original datafile is 18 KB; there's no way we could run this as...

So bugs: Early wordwrap on the last word in a string Can't input lower case on defined words (you can on cardinal directions as they come from elsewhere) VDU controls mess stuff up. I may fix those. But, as far as I'm concerned I can live with those; and this is now version 1 and can be released. Wh...

After hexedit died I moved to 010, which offers a template structure using a C type language so you can mark out areas. I also used this professionally for other reverse engineering (alongside Ghidra), enough that I ended up buying a licence.

I made my own adapter board for a Raspberry Pi and less than 50 lines of python was enough to read an EEPROM by bitbanging. I was surprised by how simple the whole process was.

Sorry it's taken this long to update - I've sat down and rewritten the print buffer routine from scratch. I'm still not happy with it, but it works better now and can word wrap more than one line.

I've played through manually to the end and noticed no obvious word wrap problems.

I alpha tested it BitD and I still have the discs. I have been trying to get my greaseweazle working, and can try and make a copy.

For I ended up enjoying finding cheats and breaking protection more interesting than the games themselves and I kept this when I moved to the Arc.

I still have a host of Electron cheating programs that I wrote BitD.

In theory you just need to AND the buffer with &DF to convert. But I have a weird bug where it's not working; I need to dig.

The bloody word wrap is sending me mad. I may have to steal ^W borrow a routine from someone else...

Back on page two I posted up a sample MODE 4 image, converted from the Atari graphics. I can reduce the size of the image to ~ 2 kB; but there's 27 unique images so I'll need to do some file munging so I don't hit DFS limits on size. I'm concentrating on getting a MODE 7 release, then making sure th...

Wow; all the MODE 7 and word wrap stuff has added nearly a page to the assembled code size. I need to look back and see whether I can shrink some of the extra bits!

Stopped the escape condition as this would make it go weird. There's still a bug on accepting lower case input; which I'm not certain why it happens. For now I'm just going to say "put caps lock on".

GET BATTERY should return an "O.K." message but doesn't return anything. It should; but this is a bug in the original database - as is the same as on the Spectrum, as this is more than a quick change to the strings, I'm not going to change it. "Small Ham radio" should be "S...

Right I've fixed the word wrap - it was a logic fault where the print buffer overflowed before any spaces or CRs in it. I will have to redo the wordwrap routine as it only word wraps the first line in the buffer. Anyway, to Lurkio's comments; in general I'm assuming that Howarth's version is a cut d...
