Remember all those old programs that claimed to speed up your floppy drives changing some parameters in the DPT?, I do.
I was tinkering with a couple of those old utilities (Quick Floppy and Flop) trying to extract more juice from a Gotek with HxC firmware installed. I know that floppies are slow in nature and you cannot expect miracles but I still think that it would be interesting trying to optimize DPT values specifically for floppy emulators. These are the relevant DPT parameters:
* Step rate; since there are no head/tracks involved I think the best value is the minimum (0Fh). (32 - 15 * 2) ms -> (2ms)
* Head unload time in milliseconds. Again the best value seems to be the minimum (00h -> 32ms)
* Head load time in milliseconds. Again the best value seems to be the minimum (00h -> 0 ms)
* Motor wait timer. There is no motor spinning so, IMHO, this value does not really matter but we can put here the maximum value allowed (FFh -> 255 timer ticks, about 20 sec.)
* Head settle time. The best value seems to be the minimum one (00h -> 0 ms). This parameter is configurable in the latest HxC firmwares (default 12ms)
* Motor start time. The best value seems to be the minimum one (00h -> 0 sec.)
What do you think about this?

Re: Floppy disk "accelerators"
yes i think that you can set all parameters to theirs minimum value.
