Summary MESS-specific 06689: cpc6128: Loading a disk freezes the emulator
Description Every time I try to access to the disk from the amstrad command line, the emu freezes (not sure if it's a freeze or if the keyboard input is disabled). The only way to recover mame is to close it trought the Windows task panel. Deleted any .ini file before, and the issue is still present.
Steps To Reproduce 1-Use File manager at amstrad 6128 to load an .dsk image.
2-Access disk using CAT or load it using |CPM.
Additional Information .dsk files can be dowloaded from cpc-power for testing. The cpc6128 worked fine in 189.
Regression Version 0.190

That is strange - it seems to hang MAME entirely now. I used the softlist item "pacboy19" for testing.
My testing back seems to indicate it was broken by this commit for the upd765 on September 13, 2017:

It may also affect a number of FDCs in other drivers which will need testing.

This bug is fixed by which is in head now and I expect will be in 0.191.

I tested the CPC6128 with "pacboy19" and was able to successfully reproduce the bug before, and successfully execute "CAT" and load/run "pacboy19" after this fix, so I'm confident it's resolved.
