A monospaced 3x5 font used in Vidora15 and later programmable electronic displays made by AMFA Cybernetics (formerly "ATMA Robotronics").
This font is made with AMFA encoding in mind. As such, the character set is very limited and there are no glyphs which require NKRO>1 or buckybits (Alt, Ctrl, Fn, Shift, Strg, option keys, etc). The glyphs normally present at these codepoints have been reverted so that any text displayed in this font is also effectively displayed in AMFA encoding. The encoding has 48 possible glyphs (including one which doubles as both "null" and "new line") so there are 96 glyphs in this font overall.
Hope this saves you some work, Feng! :^)

Since this exact font and encoding scheme were used in other devices and software, some of which were (or had) games, I'm also tagging this with Game Recreations.

Original size: 4pt (use multiples of this size for pixel perfection)

Presenting Tokumashoten intermedia (formerly Tokumashoten or Tokuma Shoten)'s Famimaga Disk Vol. 1: Hong Kong's released in 1990. This game was based on Famimaga Disk Series, released in 1990, by Tokumashoten intermedia.
A single line is bent on itself to trace letterforms in 5x5.
This is part of my "IVO" series (Inline Versus Outline) wherein inline and outline elements are split, merged, and altered to make them ambiguous and to allow new styles to emerge. They may look like maze fonts, but they have a different design methodology altogether.
