I made a simular diskrom as Guillian describes (using Arjan Zeilemakers disassembled diskrom sources). It is a generic rom, and can be used to convert any dsk image. Ofcourse, the images can only be accessed read-only (and you need a big enough flash cart to flash double sided dsk images), works great with the msx1mania disks

Or download immediately.

Can I use this with MegaFlashROM SCC? (FOr single sided disks.) How to proceed?

Impressive, even if you say it was a piece of cake. It's very useful for diskless/broken MSXes.

Now there's a reason to build 1Mb FlashROMs...  |

Thanks guys!
Updated the diskrom; fixed loading into page 1 (thanks Ramones!) and switched to
ASCII8 mapper (still write to the KonamiSCC mapper address too though, so it actually supports both).

I have tried Undeadline and Sonyc in a 1024 MegaFlashROM and it works flawless!
Vincent, thank you for this amazing diskROM!
Now it is possible to make ROMs of games like Bomb Jack, Pang, Sonyc and lots more |

@Vincent van Dam
Great Work!! Greetings and thanks ror sharing it.
BTW Can I give you a suggestion?
Add compression!
Use something like pletter to compress each sector
or group of sectors and put decompression in
the DISKROM.
A lot of disk games would become accessible also
for 256K expansions

Compression: great idea! It will probably still be about as fast as a normal floppy! And it might be enough to fit most 720kB games in a MegaFlashROM SCC with 512kB... (which is standard). |

And to offer a retrofit for the 512 SCC model, for a small fee of course  |

I like the compression idea, working on it! 
(I'll make it hybrid again, supporting as it is now, but with a custom pc tool to convert dsk images with compression applied to it.) |

Look for pletter by XL2S,
you'll get a nice PC compressor (with C sources) and a light z80 asm de-compressor
