Revision as of 05:54, 16 July 2019

This page is designed to allow for a quick look over all the drivers with a MACHINE_IMPERFECT_TIMING flag by giving, as much as possible, an idea on the amount of effort needed to fix them.

aristmk5

Games are running at double speed.

cv1k

Games are running faster than on real hardware.

fidel_as12

Seems a little bit slower than the real machine. Currently, a dummy timer workaround is needed, or it's much worse. Is the problem here is due to timing of CPU addressbus changes?

fidel_eag68k

feagv11 - V11 CPU should be M68EC060, not yet emulated. Now using M68EC040 in its place at twice the frequency due to lack of superscalar.

fidel_elite

fidel_sc12

Seems a little bit slower than the real machine. Currently, a dummy timer workaround is needed, or it's much worse. Is the problem here is due to timing of CPU addressbus changes?

konamim2

Games are running slower than they should.

mmodular

I/S= diag speed test doesn't match real hardware.

taitojc

Games are running at wrong speed(unthrottled?) compared to pcb recordings, easily noticeable on sidebs/sidebs2, for example the selection screens are too fast, and the driving is almost twice as slow.
