  OIDS for Atari ST

Hard disk runnable v.

Src: STX img. of org. This has pretty good copy protection +
good code protection. So, I spent some time with it.

In case of problems on TT and Falcon try with disabling CPU cashes
before start.
Tested on Atari Mega STE - works fine at 16 MHz too.

Added trainer options.
