@eg0n I'd say that's definitely pretty close, and I'd probably go out on a limb and call it synthwave.
Although, as a long-time synthwave fan, I want to say that the sound is just a little too clean - it's missing those MIDI string overtones and chords that are kinda the signature sound of synthwave. Do you know what I'm talking about? Like, that whole "string section" patch or MIDI sound is what I'm talking about. I don't really know how else to describe it.
Your version sounds like synthwave for the NES (not meant to be disparaging in any way, just meaning to capture the digital "clean-ness" of it).
