Hmm. That sounds interesting
The current version of 1.x hasn't improved the timing issues/accuracy and sound emulation since 0.9x. The CPU core was still off in cycle times, some of the video display emulation is missing, it's not handling the 6 dac/audio channels correctly - you can't pair them in ME, etc. But I wasn't aware that he was doing some tests on the real system again. Then again, mednafen source is open so one only needs to look at that to get an idea (a number of us have submitted our own tests and have done tests for the author to improve accuracy). I was genuinely surprised when DM made SGX hardware emulation available to any rom in 1.x (not that it's 100% yet, but still). Anyway, things are looking up for ME I guess.
