I love these kinds of lists!
A small addition: Develo Startkit Basic-hen (TICD-6007) has two sample programs supposedly made in Basic for Develo by MSX-FAN magazine readers. One of them is "Mouse de Rakugaki". I just tried it with my mouse and it worked as advertised.
Why is Forgotten Worlds the only 3button game on that list?
Yes and I don't think a list of 3-button support games makes any sense in the first place (Esteban's 3-button Friendly Games list makes sense though).
Also the Backup RAM part of that list looks really small and has lots of errors. I like the Analogue Controller list though, as that's something I haven't found much info about.
