Back in my teenage years (around 1992) I recorded in VHS (but overrecorded it afterwards) a certain console game's opening sequence from a game TV show and attempted to transpose the background music to a MIDI file. Here is the converted MP3: https://ia601408.us.archive.org/29/items/GAMEUNKN/GAMEUNKN.mp3
I can't remember much of the opening itself (I paid more attention to the music at the time) but I can remember it had spacecraft in a space war setting, so I'm guessing it was a Shoot 'em up.
I assume the song was from a Sega Genesis (branded Sega Megadrive here in Brazil) game or some 8-bit console released here at the time (NES, Master System). It could also be a TurboGrafx-16 game (PC Engine outside North America).
I've been trying to identify that particular song and game for years. Hope someone can help, even though the transposal is not particularly accurate.
