See title. All sources I could find other than this leaderboard say 1987.

It was also released on the FDS not the NES

ok i changed "nes" into fds. as for the year i don't think we can 100% confirm the year, it was on the back of some lost level disks. most of the information i could find on tonkachi mario was on youtube and stuff like that. should i change the year too?

If we had a source that said 1987 I’d say we go with that. I don’t think it’s too big of a deal. I’ll take a look but I don’t remember finding much about it when I was researching it a few weeks ago
