On ebay sometimes I see MSX2 computers with a 'Fast DiskRom' I wonder, is this an adjusted MSX2 DiskRom or is this the MSX2+ DiskRom ?
I have the possibility to program my own eprom's and als have the 2+ rom files, so if the fast diskrom is the 2+ rom I can try this out on my NMS8255, if it is not the 2+ rom, but an adjusted MSX2 Diskrom then I would like to know were I can find the Rom files to do this adjustment.

Fast! Diskrom was made by Adriano, for Brazilian floppy interfaces. It has nothing to do with internal MSX Roms.

The description on the site: "a new ROM for port-based FDCs (write the file to cartridge EPROM), fast, with new features and fully DOS2 compliant (in portuguese)"

You can get the EPROM file here

SLotman: hehe, I don't think he means Fast! Diskrom. Since a long time there have been adjusted EPROMs in the Netherlands with a faster diskROM than usual. In my own Sony HB-G900P, for instance, there's a modified NMS 8245 diskROM, which is much faster than the standard Sony diskROM.

If someone's interested, I guess I could dump it, so that you can study it.
