JEmu2/MSX version 4.0 released

I just release (about 5 minutes ago) a new version of JEmu2.
As for the MSX part, these are the changes:
* Disk emulation (press F8 to switch disks for multi-disk games, disk writing is not supported)
* Added rudimentary VDP timing
* MSX-Music sound is now also stereo enhanced like SCC/SCC+
* Some little VDP fixes here and there
* Added Snatcher, SD Snatcher, Aleste 2, Aleste Gaiden, Fire Hawk, Undeadline

I'm pretty pleased with the stereo enhancement effect in both SCC and MSX-Music emulation. The already good SD-Snatcher music for example now really sounds better than the real thing IMHO. Maybe something to add in 'blue' and 'open' too?

NICE!!! is there a way to play that Nemesis2 smooth scroll on a real MSX?

This emu is amzing for being programmed in Java

Thanks :-)
The smooth scroll is done using a specialized driver for Nemesis2. It reads some timer from the MSX' memory and translates it to a pixel offset. Ergo, no, there's no way on a real MSX.

too bad I'm working on something cool for openMSX through a TCL script... but it won't be smooth scrool... I wish.

'Something cool for openMSX through a TCL script'... sounds intrigueing

So how do you like the stereo effect?
(you can disable it in the front-end to hear the difference, especially using headphones)

If needed, I could share the code of the modified SCC and 2413.

erikd: that would be cool You'd need to share it under a GPL compatible license, though.

Well, the SCC and 2413 implementations are basically existing implementations translated to java, which I have modified for the stereo effect. The modifications are quite straightforward, really.
I could even just explain what I've done so you can implement it yourself.
In any case, I really have to prepare a new source release anyway, but I see no harm in letting you peek in the source before that, so you can implement same thing yourself?

Exactly, what are you doing with the mono sound?
