Hello, I'm lifthrasiir  and I'm the guy who wrote the "Guide to understand BMS format" while developing a minimalistic BMS player called Angolmois .
I'm surprised by the completeness of your BMS command memo, and even more surprised when I found my humble and quite outdated guide in the references!
Anyway, I was glad to see your research (including your diary, heh). Keep up good work!
私のメモが翻訳されれば、私はとても喜ぶに違いありません。 しかしどうか、너무 무리하지 마세요 ?
