I've seen weird stuff of MSXMEM even in emulated MSXes... so better check that out Smile

Okay, I’ve never seen this on the real machines I tried it on. I will have to wait for my CF2700 to return to be able to confirm gdx’ findings. I will try creating an xml for the CF2700 based on what we know now (no MSX-Engine, 32kB RAM in slot 0 besides the MAIN BIOS/BASIC) and 2 primary external slots).

You get the same when emulating the YIS-503, with an MMM in slot 1 and a Sony HBD-F1 in slot 2:

I get the same when emulating the CF-2700, with a 512K RAM in slot 1 and an IDE Sunrise in slot 2.

There is no longer any doubt, MSXMEM is buggy.

You can found it in the ZIP at the link I put above.

Okay, I am apparantly using a newer version of MSXMEM.BAS that does not show this issue.. Here in openMSX 0.15 with YIS-503, a 4MB memory mapper in slot 1 and Panasonic FS-FD1A in slot 2.
