I got this one for you (NTSC only):

----------------------------------------------------
       |                  COMMAND (kb / frame)
 MODE  |--------------------------------------------
 60Hz  |  LMMM  |  BMLL  |  BMXL  |  BMLX  |  LMMV
----------------------------------------------------
P1 sON |  6.125	|  6.125*|  7.875 |  7.250 | 12.875
   sOFF|  9.125 |  9.125*| 11.500 | 10.375 | 19.250
----------------------------------------------------
* double in case of copying to plane A en B at the same time.

I remember there was an even more detailed one on GitHub, used for tuning speed in openMSX if i am not mistaken.

Wow that's slower than I hoped... I'm going to have to beg Jorn for the interrupts so I dont have to hang waiting for commands to finish Smile

That test case already exists: Beast
directly from github link as issue to be solved, guess it snowed under ;)

This issue should now be solved. Please try the latest development build. The cause was totally different than you thought, though. See the issue link :)
