SofaRun v2.0 released
1' With roms disk access is allowed to save progress when possible. Youk youk, Metal Gear 2 is going to be replayed by me. I think you were talking about real disk and not also a virtual usr disk as sofarunit make.
That was already available in SofaRun v1.0. If you launch a ROM accessing disk (or a ROM with Game Master), it will be able to access your MSX-DOS 2 file system. Metal Gear and the Game Masters are saving files, so you'll get them on your SD card in the ROM directory, or in the SAVEPATH directory that you can define in the SR.INI file.
Note that you can save to a real disk by setting it to "C:", but there's not much interest in it 
2' what are the file extension accepted for screenshots? Any idea on how use/convert PNG, MIF and JPG I have in my launchers?
Those are now .SNP files (and not .MIF anymore). I had to change format for faster loading speed. I just added a snapshot pack on my site (look for "Snapshot pack").
Laserdisc software emulation on MSX, really 
? No way to do that, it would be waaaaaaaaaaaay to slow (you alreay need a good PC machine on emulators !), and can't be done because the Laserdisc image is displayed in the background (it's not a real screen 2 image). We could just dream of an enhanced MegaFlashROM which could read and decode the video files from SD Card, and send the video signal to the "superimpose" video channel or something...
More seriously, next steps in SofaRun will be support of long file names, and custom file extensions in the SR.INI file.
