This is the font used in my Scratch projects that use SSEGA OS, SSEGA OS 92, and SSEGA OS CD (https://scratch.mit.edu/projects/938150503/ https://scratch.mit.edu/projects/938615942/ https://scratch.mit.edu/projects/939136020/). It has a lot of characters in a 4x5 bounding box.
please clone this if you want to extend this.
NEW UPDATE!!!: added more latin fixed 0-9 and added greek
Note: I found the character for "U" was broken and the only way to fix it was to use another software. I'll stop rambling heres the fixed file: google drive
