Diagnostic Command is it Bugged?
Back in the 80's I created a Disk Protection system, exploiting a potential bug in the Firmware of the µPD765A Disk Controller. Looking into this more with todays tools, it seems that the disk record and this specific command isn't implemented as per the specification. Is it my misunderstanding or is there a bug that's gone unnoticed?
Speedlock 1987
Speedlock '87 was a prolific Tape Protection System and Turbo Load for the Amstrad CPC and ZX Spectrum. In this post I look at the protection system and how to hack to it using the same tools available to me in 1987 as a young teenager.
NOVALOAD – Commodore Speed Load and Protection System Hacked.
NOVALOAD Turbo Load and Protection system was ubiquitous on Commodore machines back in the day. I take a look back at how I hacked the protection system when I was around 13 years old, though today using modern day tools. Revisiting my past exploits and sharing information with the greater audience. If you're a fan of the C16 and Mr Puniverse then take a look and follow me!
MegaVault Hack – Part 2 – Creating a Loader
Following on from the Back to Basics article, in Part 2 I'll show how to create a custom loader for MegaVault that we hacked. Additionally we'll create an old-school magazine style type-in for cheating on original hardware and cassette.
Modern Day Old School?
I blitzed my way through any protection system I could lay my hands on, we had everything from Speedlock, Appleby, Bespoke, Turbo Loaders, Musical Loaders and the general gaming community wanted games transferred from cheaper cassettes to disks. It didn't take long before I developed a number of automated tools for cracking back in the day.
