i need your help....:crying

i´ve started to get understanding this bootblock yesterday but currently i´m hanging (no, not on the ceiling with a rope :laughing )

what kind of copy protection is this ????

and did i understand everything right now...???

It is hardware trackloader, nothing to do with copy protections.

6011E -> load and decode track
601CE-> MFM decoding.

Basically does exactly same as http://eab.abime.net/showpost.php?p=299838&postcount=7 :)

This means that i looked to deep in code...

i just like to analyse the bootblock to find the trackloader...that means that it is starts on $2E

i just have to write a slave for WHDLoad that force the CPU to Supervisor and set the highest interrupt level, put the trackloader to $100 and the game should run...theoretical

am i right ???

that would be my first slave....

the method above works with _LVODoIo()
isn´t it a little bit more different..????
