Re: Asteroids (Allan Turvey)

Hi Pere,

Very nice work!

In which address is the AY chip mapped? Would it work with the JCB Sound Extension Module?

Cheers,
Rob

Re: Invader's Revenge reverse-engineering

Hi Ben,

Thank you for the nice explanation of your setup!

Isn't programming a fragile collection of scripts? :mrgreen:

I'll be taking a look and see if I manage to generate some good looking html like yours.

Cheers,
Rob

Re: Invader's Revenge reverse-engineering

Hi Ben, welcome to the Dragon Archive!

You've done a remarkable job with the reverse engineering of Invader's Revenge. I like specially the comments, the different coloured blocks and how you show the embedded graphics.

How do you create such visualization?

Cheers,
Rob

Re: CoCoSDC and DragonMMC memory problems.

Thanks, Dave!

At first glance, I'd say you ran the program with a Joystick in the left port, is that correct?

Cheers!

Test de conducción ROM

I thought I had uploaded the rom file for the Driving Test by Belrampa Servicios S.A. , but it may not be the case. So, before I forget, here it is! The rom has a small machine code program that copies a Basic program into the Basic memory area and runs it automatically: C000: 4F CLRA C001: 86 5B LD...

Re: New tool for DragonDOS disk images!

Do you guys think that having partial support (Open, view files and extract files) for OS9 is nice or a bit over the top?... :mrgreen:

Re: New tool for DragonDOS disk images!

Hi Gérard, thank you for your nice feedback! I notice that your tool can read the DDos files without the vdk header, which is not necessary. For me it's useful because I generate a lot of data myself which then can go to a disk, a tape or a rom file, so it doesn't have a header by default. Regarding...

Re: New tool for DragonDOS disk images!

Niiiiiiice! So, would a button on the main interface, named something like "View Boot track", leading to the disassembly of the content of sectors 3 to 18 be the way to go? Then, If you want to view/edit individual sectors, I could import the hex view I did for my DragonBlock util and add the needed...
