MSX2 how to load .rom files?

[clarkkent]

The MSX2 core seems to support harddisk files only. But I have several .rom files - how to load them?

It’s a while since I fiddled with it so I haven’t any advice on setting it up, but there’s an MSX program called sofarun that will launch ROMs for you. Put it and your .ROMs, .DSKs and so on in a vhd.

Thank you for your advice.

But I would like to know why there is no option in the MiSTer menu to mount a ROM or Diskimage. The MSX 1 core has such a menu - the MSX 2 core not. And I wonder why and if there is a method of mounting them?

If you want to use cartridge of floppy disk files with MSX2, I recommend to not use the "MSX" core (which is actually based on "modern" 1chipMSX project instead of actual MSX2 computers), but rather use a beta version of the "MSX1" core upgraded with MSX2 support. It is currently listed on GitHub as a separate branch of MSX1.

The MSX2 uses a different method of using BIOS files, so I'd also recommend to look at the core description page by Vampier.

Yes, and with roms you've got to use the appropriate mapper as far as I can tell.

Eg, I can't get this to run - https://www.pouet.net/prod.php?which=97563
MSX2 but it's a ROM. I think. I'm not sure, I don't know enough about the MSX, if anyone can help.

Many thanks!
