mini MATCH Mi™

This is a digital remake of the electronic "Simon" game called
mini MATCH ME™
, manufactured by
KINGSFORD
in the 80's. All functionality is based solely on what I remember from playing it; because I no longer have the original.
It's a smaller version of the original MATCH ME™, which itself is an 8 button clone of the original SIMON game by Milton Bradley.
Supports 4 game modes; but I was only 6 years old when I last had this game in my hands so I have no idea what game modes 2 and 3 actually do. Currently they're the same as game mode 1.
Game mode 4 is "piano mode", and the game included a manual with musical scores to be used with it.
Automatic music doesn't work because I don't know which music tracks were played.
The winning jingle is taken from Battle City, because I don't know what the original jingle was.
Any information on this electronic game's functions is welcome.

Easter egg:
If you play Happy Birthday while on piano mode (1,1,2,1,4,3,1,1,2,1,5,4,1,1,8,6,4,4,3,2) a yellow button will appear. If you hold it down, all the notes you press be lowered by a half step (So button 3 will play E♭ instead of E).
