Re: More Boulder Dash!
No import capabilities here - and I still have a few Ts to cross and Is to dot - but I'm almost done putting together an editor that allows Bill's standalone level files to be edited on a Beeb/Elk :) It amazes me that you've squished it down to a single screen! Do you have plenty of memory for the ...

Re: More Boulder Dash!
I've compiled a list of memory locations within the editor and think amoeba growth / magic wall time would be at 4C54 Since there's only one or the other (or neither) on a level, I suppose it's a useful space saving technique! 3C00 CAVE O, LEVEL 5 3C46 CAVE H, LEVEL 1 3C70 CAVE H, LEVEL 2 3C9B CAVE ...

Re: More Boulder Dash!
The game is just loading the "crunched" level, 400 bytes in length and expanding it to 800 bytes, so it's probably quicker than calling the 4/5 routines to create the cave. I hadn't actually played it so much realise that the level changed the cave layout, i just figured the parameters of ...

Re: More Boulder Dash!
Luckily the bonus caves are numbered sequentially from the main caves, so I just needed to add Q, R, S and T
They're the same sized caves from the program's storage perspective. I had to modify the third bonus cave, but it was quick and easy with the editor, so I guess it works well enough

Re: More Boulder Dash!
After getting stuck with why some items disappear on the map program, I looked into the idea of cave replacement.
Some marginal success with the loading of caves, I've got A, B, C, D and E saved as individual files, loading as necessary - cave storage / retrieval works fine

Re: More Boulder Dash!
The "randomly" generated approach of BD1 caves doesn't seem amenable to any sort of useful modification but I presume the later games in the series must use a more sensible format (to allow them to be edited in the Construction Kit). Would be interested to learn more about how the caves f...

Re: More Boulder Dash!
Can confirm that it's down to the low 3 bits, and also that the high bits in each case should not be disregarded. Messing with them (somehow) causes changes to the cave generation. The lower 3 bits are used in the basic and details part of the map generation, the walls section requires some more, 1...

Saw this on Facebook (Acorn Computer and BBC Micro Enthusiasts)
The instructions helped me enough to manage to finish the first level!
If the original author (of the game and/or FB post) would rather it not be here, I'll delete the post - although it is out in the public domain now

I'm basing my assumption on the fact it says the Cyclops runs through the wall, creating a hole which can be traversed by going south.

Re: Labyrinths of LaCoshe - My 40yr quest for enlightenment
There appears to be a flagrant bug in the .ssd version downloaded from the BBC archive. After killing the cyclops it is impossible to enter the hole in the south wall. Indeed if you leave the cyclops room and return either from the skeleton room or the thief's lair the hole has disappeared. Hi, Wou...

What happens if you omit the command codes altogether?
Or could you try putting them all on one line?
It would seem that each command code is taking up a line on the page

The 80 track version has 60 puzzles split across both sides ~ 140kb total This version does prompt to flip the disk for the higher number puzzles I guess the two sides were only required due to the 31 file limit, as I removed the 40 empty tracks on the SSD https://www.stardot.org.uk/forums/viewtopi...
