About the MegaSTE, just turning the cache off doesn't really emulate a STE, for example, the blitter starting delay is different on STE and MegaSTE and it can be a problem.

Yes, there is a delay of 4 cycles on the MegaSTE. So if someone uses the Blitter in synced code like fullscreen there are needed two different routines for 1040STE and MegaSTE.

As far as i know this is the only exception if the cache has been turned off the and the CPU slowed down to 8 mhz.
