That would be great. It would also be nice if you could run some basic tests on it, to verify slot layout and other details.

You can get the tools for this from this thread.

I received the YIS-604 rom dumps from MSX4Ever. As expected they are identical to my CX7/128 and the CX7M/128 (and many other MSX2 machines). The zip also confirms slot layout is the same as those 2 machines so emulation is just some renaming in the XML. I would be interested in a detailed comparison of the CX7/CX7M/YIS604 mainboard from these machines (mine has a circle around the CX7 so somehow they put different parts on the MB)...

So, it's identical to CX7/128, apart from the meta data (model name)?

What are all these other ROMs doing in that zip?

Hi, sdsnatcher73
SHA of the yis604ext.rom in your zip is 0fbd45ef3dd7bb82d4c31f1947884f411f1ca344
not b8e30d604d319d511cbfbc61e5d8c38fbb9c5a33.

Which is the correct one?

Oops, I uploaded the wrong yis604.zip Sad. If you download again you get the one from MSX4Ever, the one you got was the MAME one (which is incorrect), but both files where called yis604.zip Wink.

Sorry wrong zipfile, please redownload... And yes it is the same except metadata (and as mentioned there may be minor differences in components on the mainboard but without further investigation we won't know).

Thanks all, added config to openMSX Smile

MSX4Ever: do you have more machines which are not in openMSX yet?
