Hello,
I've recently created a MSX VHD to use with MiSTer FPGA MSX core (basically a OCM implementation).
It boots straight into SofaRun 7.0 via autoexec.bat - after much trial and error I got the full Konami library .ROM & .DSK working flawlessly. All known versions, translations, enhancements etc. Neat. Dream came true. I'll place it on archive.org one of these days if it can be of any interest.
So, the next obvious step was to have it work on real hardware. With a friend we are trying to have it work on a Philips VG-8235 with a MegaFlashRom SCC+SD.
Checking some old posts here and there on msx.org, we understood that we had to erase the ROM Disk (F3 from recovery menu). This way we can have the SD card becoming A:
And indeed it works! Sofarun boots. Every Konami ROM boots using the very same settings we used for FPGA (which, in fact, reproduces a OCM with two MFRs).
BUT!
DSKs don't work. SofaRunIt hangs before having the disk start. And even MultiMente's ep.com, after erasing ROM Disk, does not work anymore. They worked before, in the "out-of-the box" MFR SCC+SD configuration.
Multimente, when trying to load adsk says
NOT A A DOS DISK READING DRIVE A: Abort or retry? (A/R)
So the question would probably be: how to setup the SD card in order to boot SofaRun and have .dsks working after removing ROM Disk? Which files/configuration are mandatory?
I'm pretty sure that for you, gurus in the know, this is a trivial question (and yes, we did thing whithout knowing exactly what we were doing 
)
As I said it's a Philips VG-8235.
SofaRun says
TPA Memory 17600

Thank you for your patience!
