Interesting. I had found the Gradiente CT-80E, but that one has a V9938 inside. About the Toshiba, I'm not sure. If it's from 1985 the V9938 would have been available. The screenshot looks more like V9938 as well, but the magazine could have inserted a MSX2 image because that's what they had available.
However, the most worrying part is that we only have this announcement. Not a single review. Did the cartridge ever get released?
I think it is not necessary to put the commands for MSX1 in the wiki page below when they do not have a function specific to DOS2.

A remark "Not MSX-DOS 2 compatible" in the MSX-DOS_1_Tools#Commands page when this is the case is enough.
In this case, you need to adapt the introducing text (to link to the MSX-DOS 1 Tools page).
About the Marconi RB2, I don't know if there is a version for MSX but pictures and manual of the BBC Micro version are useless for MSX users in the wiki. It can make believe that we can buy this model for MSX.

In addition, if a MSX version exists I don't think the buttons are assignable.
I! was advertised and reviewed in a Dutch magazine (see Generation-MSX).
I don't question the existence of the MSX version but I say that pictures and manual of the BBC Micro version are useless and I think the buttons are certainly not assignable.
I've adjusted the text for the buttons.
The pictures are not useless, as the external look is the same for the MSX version, according the advertisement.
So I will only remove the link to the manual, but smart users will find it anyway, thanks to Google.
Wiki says about the M File manager:
''Warning:''' Do not copy, delete or move a file with a long name under MSX-DOS 2 / Nextor because the Kernel doesn't support long file names. The FAT wil be corrupted if you do it.
Just wondering: what is the point of long filename support if you can't manipulate the files anymore with your MSX? Is this limitation real???
In fact, M File displays only the long name of the file selected at the cursor. This is useful for ROMs, DSKs, musics, etc which are composed of a single file. This makes it easier to recognize them. You just have to handle these files/folders with a PC. Files with a short name remain handleable with the MSX.
Is this limitation real???
Of course, before I thought that multi-mente was not reliable but issues came from there.
Sharksym also put this warning in the doc:
[주의]
LFN으로 된 파일은 MSX-DOS2 커널에서 인식하지 못합니다.
해당 파일을 복사/삭제/이름변경 하면, FAT이 손상되므로,
읽기전용으로만 사용하세요!
I can imagine that after moving or deleting, the long file name can stay behind or not updated. But I wouldn't expect the file system to get corrupted.
