Re: New Year, New Project (Skirrid)

I think the reference I used for RLE was this https://codebase64.org/doku.php?id=base:rle_pack_unpack , but it was a long time ago and it is possible I used the one from the MADS examples. Other more effective compression algorithms are available (and I think have been recently discussed hereabouts)...

Re: New Year, New Project (Skirrid)

It wasn't actually that quick, I wrote it in 2017 for the Atari (using MADS), then got bored with it and ignored it for 18 months. The port to the BBC / CA65 then back to the Atari (now also in CA65) represents the equivalent of several weeks full-time on it, but all the hard work (game logic, tiles...

Re: VDU-stream 'sprites'

Of course the whole approach would be much more suited to vector graphics than bitmaps, which leads me to a tangential question - is there an SVG to BBC VDU command converter...?

It's a poor quality image, but this appears to be a Model B with some sort of cheese wedge add-on being used during SelfAid in 1986.

Re: Building a Console app on Mac using .Net Core 3

This process "restores" quite a lot of stuff, not sure what that really means, but it puts a lot of libraries in the publish folder. Personally I'll stick to running the DLL from a shell script for the handful of utilities I might write, or just stick to the older .NET framework for now.

Re: Building a Console app on Mac using .Net Core 3

According to Microsoft, generating a DLL which is invoked using dotnet name.dll is by design. However, you can build an executable using dotnet publish -c Release -r osx-x64 From the folder which contains the project file. But I think I'd just create a shell script to invoke dotnet myself.

Re: Revised BASIC framework and tools to build an adventure

Here is a working example, running on a Mac, outputing Windows style line endings.

\r = CR, \n = LF

In response to an earlier comment, # = ALT+3 on a Mac, but it's not shown on older keyboards!

Re: Revised BASIC framework and tools to build an adventure

StreamWriter derives from TextWriter which has a NewLine property which defines the line endings. I think this defaults to the "normal" value for the platform, but you can change it so something else.

Untested, but from reading the documentation, I think that will solve your problem.

Re: Seeking ways to showcase fast second processors

Sudoku

If you use T.BIGED on the SSD, timings are as follows.

Master = 114.5s
Master + 1Ghz PI = 6.5s
Master + 1Ghz PI (fast mode, so no screen updating) = 1s

Re: Seeking ways to showcase fast second processors

For what it's worth, you could point my Sudoku solver at some really hard cases. It's 2nd processor friendly.

Visually not that impressive though and if you're looking for some thing to demonstrate, a hard puzzle doesn't look that different from an easy one.

Re: A simple text adventure: MoonBase Escape

The Electron lacks MODE 7 (1Kb) and MODE 6 (monochrome) requires 8Kb so that's going to consume 7Kb out of the 4.5Kb I think you had left.

Not that this helps at all...

Re: Loading assembler code

Jumps and subroutine calls (JMP and JSR) are absolute, branches (BEQ, BNE etc.) are relative, but limited in range to -128 ... +127 bytes, effectively -126 ... + 129 from the branch instruction.

Re: Struggling with file handling - B2 emulator

One thing which caught me out recently was that my image writing program will allow creation of a short image. That is, just large enough to contain the actual files, but not the empty space. This (obviously in retrospect) stopped me being able to write a new file to the image. So if you have a SSD,...

Hello Paul,

Yes, there is a playable prototype in this thread viewtopic.php?f=53&t=18459.

Edit. It a sideways ROM image, but not actually playable online as such.

It's still a work in progress, but the game is playable.
