MARIOFont

The Mario fonts you usually see in Mario games in binary format. Currently this repo has: MARIO_Font_v3_Solid.otf and MARIOMAKER.otf

MARIO_Font_v3_Solid.otf

The UI (time and score) and logo font in most Super Mario series.
This file is found in Mario Tennis: Ultra Smash, and again is used in Super Mario Run. In Dr. Mario World, the font file is updated and embedded inside globalgamemanagers (a Unity archive file).
It supports basic Latin, full Hiragana and Katakana, some Kanjis, and some Cyrillic characters.

This is a custom font created by Fontworks and Nintendo holds the rights to it. Latest version is v3.203 on 8/20/2019.

MARIOMAKER.otf

This is the official font of Super Mario Maker 2, used in its logo and most of the UI. Version 1.3, last updated on 11/28/2018. Extracted from yuzu emulator, and decompressed from WOFF to its original format, OTF.

Mario Maker vs. Mario Maker 2 font
In Super Mario Maker, the font is called MARIO30th instead (found in SCHOLASTIC Super Mario Maker 3DS's PDF).
MARIO30th apparently lacks lowercase characters or it is available? - probably just for amiibo word, which is then added in MARIOMAKER.otf.
