Planet Nubium : A game for the BBC Master

[AW11Ghost]

Well done, it looks really good!

I've just noticed that Planet Nubium 1 & 2 versions on bbcmicro.co.uk https://bbcmicro.co.uk/explore.php?id=2969 have invalid catalogues.

The files are not in sector order and the !BOOT files look a bit funky too!
They look like tokenized lines of BASIC and have run addresses of &802B (don't know which BASIC version, but maybe Master) but the discs are set to *EXEC !BOOT.

On a related note, it would be nice for the explorer view to show the start sector for each file

Does anyone have any idea what happened or if there is a FS that doesn't require the sectors to be in order - maybe it was a copy protection measure :O

The only thing I can think of is that all of the files have been overwritten many times since I made the disks bootable. There certainly is no deliberate 'copy protection' !

Thanks for confirming.

I wonder if it is an electron thing.
Which tool do you use to create the .SSD files?

What about the !BOOT file, should that just be CH."..."?

[Andrew_Waite]

I create the .SSD files on a PC using BeebEm (Version 4.17), then test the game on my Master using a USB stick and a Gotek drive for file transfer.

Amazing game

You may want to add a *fx 200 1 to the !boot to disable the ESC key from breaking out into basic ?

[lovebug]

can you post the command line you used to create the .ssd

thanks

can you post the command line you used to create the .ssd

thanks

Thank you for the kind feedback on Planet Nubium. Great to see Lady Bug has a superb port to the Beeb, along with the sound effects!

To create the .ssd file I use the FILE -> DISC OPTIONS -> NEW DISK 0... command from the menu of BeebEm. I edit my code in BBC BASIC For Windows, and then copy and paste directly into BeebEm. The 6502 code is assembled using BBC BASIC's inline assembler.

There are a few lines of BASIC in Planet Nubium's game loop, and it is a minor source of pride to me that the ESCAPE key works in the game

[lovebug]

ah the .ssd creation process isn't what I was expecting at all !

as for the esc key for me it just quit the game back to the basic prompt and I thought this was unintentional . sorry



and thanks for the kind words on ladybug
