Updates to i86 CPU core to fix problem with cirtain combinations of instructions being flagged as illegal on the i186. Update to wd17xx to re-add multiple sector writes as required by rmnimbus Minor updates to the rmnimbus driver to return it to a working state.
About the Nimbus driver fix I´m not sure. It hangs on my build and will not load MS-DOS. Can be the reason the MAME 0.141 core update or my build ? Someone can test it, please ? The test software is on FTP for Devs (incoming folder).
