In the 80's I started with a few cracks from programs on tape. Using a combination of Basic and a basic knowledge of ML, I managed to crack a few titles (especially Gremlin Graphics stuff). Later in the 90's I did a few cracks, using some programs a friend of mine and I had written and a bit of extra hardware. One tool was called 'sector sneaker' and was a tiny program which registered every sector which was read/written. Output was sent to the printer. The hardware was just a simple home made 64KB SRAM cartridge with WriteProtect switch, used for a debugger (WBASS). In most cases cracking MSX protection schemes was a piece of cake.

Nowadays it would be nice if there was a tool for the PC which could make 1:1 copies from MSX disks and turn them into disk images or vice versa (including protection schemes of course). Cracking is quite difficult, because of a broken Turbo-R fdd (no, not the belt!) and I want to keep the disks in 'original' state.

In any case, welcome here, MTC! Smile You can introduce yourself over here, although I think many long-term Dutch MSX-users know you, or at least your name ;)

MSX-User, wasn't it? :)

Which reminds me. He came up with the meaning of the name DISK. Just added him to the still growing list of freelancers at neardark.nl Smile

The RD Circuit designer (pixel based CAD tool)had a hardware dongle on the joystick port. As far as I know was never copied. It contained some logic whith a serial input, and next computed an output value, something with a shift register and some feedback logic. (a common way to create CRC values). If someone needs to know it exactly, i'll ask the author.

Probably simular to the ARC thingie.
