I want to upgrade my old disk transfer tool (Cloaddsk), that reads a disk on real Oric, saves it to PC using the tape save (a simple CSAVE of the read data), then building a disk image (DSK file) from it.
This works perfectly fine with Sedoric disks, I'd like to make it work with any kind of disk.
To do so, I need a routine reading a whole track, including the gaps. Nibble 2.4 does this, so I tried to disassemble it and find the routine, but after several evenings (since 2004), I'm getting nowhere. I'm lost in so much machine code.
So I thought I could locate this routine by using Euphoric's debugger (the routine crashed Oricutron 0.9). But to do so and follow the step by step execution, I have to simulate the keys that trigger the command (CTRL P, that is). Simply typing on keyboard is impossible: time to switch to the debugger, I'd miss the routine start.
So I use the debugger again, and write $9D in $0208, and $A2 in 0209, which are the values I found when I press CTRL P on the keyboard.
But nothing happens.
So my questions are:
- does anyone know how to simulate the CTRL P key combination by "poking" in RAM?
- alternatively, does anyone know where the "load track" routine starts in Nibble 2.4?
- alternatively again, does anyone have a routine (ideally in machine code, not C or ASM) that reads a whole track, with parameters Track / Side / Drive

All this to try and transfer a special protected disk

Upgrading Cloaddsk this way would be the ultimate transfer tool, reading on a real Oric any disk format.
Thanks!
