	* All 68040 machines: MAME's 68040 cycle timings are too pessimistic, so the 68040 lacks the full performance improvement you get from it on real hardware. This also affects some arcade games in MAME such as Taito's Densa de Go! and Side by Side. This has been improved in MAME 0.289, so that the 68040 now has its own unique faster base timings, and that offers noticeably improved performance in games, but it's still not as fast as it should be. (MAMETesters issue #9412).		* All 68040 machines: MAME's 68040 cycle timings are too pessimistic, so the 68040 lacks the full performance improvement you get from it on real hardware.
