Hi UberJack,
It's great to see an update already to a very promising emulator!
I have two main issues with the emulation:
1) Lack of 50hz support
This was the main screen refresh rate for European MSX computers. Most games on fMSX-PSP run 20% to fast for me now because of the 60hz timing. I posted more information about it in ZX-81's forum here:

It would be great if you could add support for 50hz to fMSX-PSP (according to ZX-81 there's already subcode for it in the fmsx sources).
2) The sound on fMSX-PSP is poor compared to a real MSX
This is probably hard to explain, but I suggest running fMSX next to a real MSX or BlueMSX for example. Then you can't miss it (e.g. the "hisses" from the PSG are much too harsh and crowding out SCC sound on Konami games).
If I remember correctly there were seperate sources available on the internet by a Japanese guy who made the soundchip emulation much better. I think these improvements have been included in emulators like BlueMSX for PC ( http://www.bluemsx.com/ ) and also the latest releases of ZX-81's PSP-MSX (though somehow still not as good as BlueMSX). Sadly I can't find the reference via google, but it must be somewhere...
Hopefully you'll consider updating the sound emulation core, as it would enhance the MSX experience by a mile
Lastly your video emulation seems to be almost perfect (still need to do some more testing though), as the scrolling of MSX2 logo on MSX reset for example is ultra smooth (like the real thing), and better than ZX-81's PSP-MSX. Of course not to forget about the very nice and clean menu layouts. Very good job in general.
Looking forward to future upgrades of this emulator :thumbup:
