Moreover, ROMs don't break down that soon (as with floppy disks), plus a ROM has just a little bit more 'feeling' Smile. Personally I think games on ROM are way cooler than disk versions Wink

I think it is possible. I made a ROM of "La Abadia del Crimen", and this games is made of a BASIC loader and several .bin files.

Not only that, but what about the problem of RAM variables Tongue Disk games run from RAM, so variables are all over the place. Coding for ROM is very different.
It's impossible.

The "trick" here is not executing the game from ROM, but loading to RAM Wink

When I said "It's impossible" I referred to a convertor program.
Ofcourse it's possible for small games to load in RAM. Hell, if you have 1MB RAM you can load an entire 720kB disk in there.
There are lots of ways of getting programs on ROM. There's just not a way that works on all programs, hence you need a deep understanding of programming and MSX architecture. My impression of the OP is that he does not have that knowledge, so discussing it is pointless.

I used a "convertor program". I just created a ESE-ROM Disk (installed the kernel, patched it, copy the files and I have the working ROM) Wink So I didn't wanted to mean that I upload the whole game to RAM, just loaded it in files when needed (as it were loading from a real disk)

You are right it more difficult to do the same with a full DSK image, but it is still possible (using modified MegaSCSI utils). Okei made a *similar* (I said similar) thing executing DSK images from compact flash.

Anyway, I agree there is NOT an utility right now (as far as I know) that converts a DSK into a working ROM.

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 Wink

Or download immediately.

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

Yes, you can;

(in msxdos2)
concat /b dsk2rom.rom+mania001.dsk mania001.rom
opf mania001.rom

done Smile

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