Hi Pere,
Very nice work!
In which address is the AY chip mapped? Would it work with the JCB Sound Extension Module?

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?
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?

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!
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...
