Mark Smith was the editor of the Konami Software Club magazine. http://msx.hansotten.com/magazines/konami-newsletters/
so my copy of the konami editor is in Sao Paulo, I do not think it's one of Saku's copies. I bought it from a well-known European collector / seller. I'll post photos.
Seems to still have the same "extra paper" around it - similar to mine. The other complete set I had did miss this paper.
So... First list. Really rare stuff.
1) Stt1 (Saku) - Complete copy
2) Currently MIA - Complete copy - Sold by Stt1 to someone he doesn´t remember
3) Stt1 (Saku) - Kanji ROM cart EC702 only - Purchased from djh1697 who got it from Dennis Hemmings
4) Ota231 - Complete copy - Purchased from "a well-known European collector"
Just made some cleaning on the hard drive - found this photo, this is the cart I have for sale / trade:
Doesn’t look like a standard Konami cartridge!
Nope, as you can see, there is also text "1985 CANON INC.". Maybe it's Canon cartridge originally and labeling made by Konami?
Neither the program cart, EC-701 looks like "normal Konami":
No, it clearly says (c) CANON. I think it means Canon was the developer and Konami the publisher, although I guess it could have been the other way around.
To add to the issue of the copyright, I searched the Kanji ROM (EC702) for any latin text that may help to clarify who developed it, but found none. No references to Konami or Canon or anybody else. I don't have the word processor ROM (EC701) to see if that contains any hints.
