[Coco] Help - CoCo emulator disk image formats...???

[Carey Eugene]

Bob;

> than the standard 35 track/1 side.

Thanks for that info!

I didn't know that and it's not in the FAQ that comes with MESS.  Or 
anywhere else, for that matter.

Things like that really should be documented....  But like with most open 
source projects, writing documentation isn't as much fun as hacking out 
code.


I had been assuming there was a problem with the disk format that OmniFlop 
generates and had tried most of them.  Or that there was a special disk 
format for double sided drives that OmniFlop wasn't doing right.


Thanks.

Carey
