Hello. One individual or another may remember my name (likely with disgust). I came across this thread through Google and I feel the need to explain a bit.
Despite being a pair of strategy games based on the Sanguo Yanyi and sharing the same title, TOSE/Namco's "Sangokushi" duo for the FC is unrelated to Koei's big Sangokushi series, and the TOSE games were never released outside of Japan or remade/rereleased for any other platform. You can easily point out these two games because their names have subtitles (Chuugen no Hasha and Haou no Tairiku). The thing is, there are tons of Sangokushi-based games, many of them strategy games. TOSE alone has made many other such titles for other systems, and quite honestly I could not tell you if they're remakes or sequels to anything.
Aside from that mess, I don't see the issue of having separate runs for conversions; this never stopped NES Mario vs All-Stars vs Advance and etc. Also, if you're correcting for No/no, you may want to correct for 2/II as well.
