Sord M5 (Japanese Computer)

Hi guys,
I was just pointed towards this core, of a Japanese computer (similar to MSX) the Sord M5.
https://github.com/tdlabac/SordM5_MiSTer

https://en.wikipedia.org/wiki/Sord_M5

Looks like it was mentioned once before here but never got a proper thread. Seems a really interesting machine, hopefully the developer can update us on it and it makes it into Main at some point.

The last update is from 09/28 so the developer is working on it.
Thanks for the info.

Congrats of getting your core officially released!

@molekula

Thanks for this core, I didn't know this microcomputer and seems indeed very close to the MSX standard!
Would it be possible to add MSX compatibility to it?
See, we lack a proper MSX1 core: the MSX core on the MiSTer (OCM) implements a strange mix of machines, none of which work right (MSX1 sound fails in a lot of games, a lot of MSX1 fail to load even with the right slot mapping pokes, etc).
An MSX1 compatible core derived from this core would be VERY welcome!

There is an unofficial MSX1 core:

That one is also buggy and abandoned

Proper MSX core with normal floppy/cassette/cart (not via SofaRun) operations is in the top of my MiSter most wanted ones. It'd probably be a huge amount of work so not holding my breath.

Hopefully that unofficial MSX-1 core gets into Main at some point and other devs can contribute.

Yes, it is true that the Sord M5 is very similar to the MSX-1. After all, the Sord M5 has a modified MSX bios and modified games to work.
As I recall, the modification consisted of adjusting the VDP and keyboard addressing. Additionally, the bios routines had to be modified to work with the cassette player.
Can be tested. Enable EM-64 + Basic - I and load the MSX bios and game from the CAS file. In the links you can trace the correct files for the test.

The Spectravideo SVI-328, for which there is a MiSTer core, is also really close to an MSX 1.
