Hi,
I am pretty sure it is a problem related to the fact that the game doesn't like the DOS installed when it starts.
The game has a routine that sets to zero all the RAM to be used for graphics from $400 on, so it is using the
working area occupied by the DOS and its buffers. The only way to start the game properly is with the DOS disabled
or not started. I attach here the source of the Switcher I put in my VDK that works falwlessly on my Tano reading the
virtual file from the Drivewire server.
I think that probably using Stephen Woolham DosDetach it should work too.
I will try that later today and will let you know.
regards
pere
Pd for sure this is not a protection scheme, I was wrong while looking for a reason to the problem
