Actually, wasn't this a known issue? https://github.com/openMSX/openMSX/issues/865 seems to be exactly this: the CIEL uses the /WAIT pin of the VDP, but that isn't emulated. The only workaround for now is to disable VDP access timing restrictions.

Wow! That was more than 5 years ago. I totally forgot that it was already reported.

Well, since the /WAIT isn't being emulated, should't openMSX disable the access timing restrictions for this machine by default? Only until the /WAIT is implemented.

Either that, or rename the machine to WIP_CIEL_Expert-Turbo, since we can't consider the machine is finished the way it its now.

Think of the average user: they'll just boot a "turbo" machine, and it will show corrupted VRAM data. They'll think that either the MSX2+ can't support turbos, or that the real machine also doesn't work properly.
