You're telling me shit I already know and trying to twist the facts
I'm sorry, but if you already know all this, why can't you make sense? You're again coming in with a new claim that falls apart the second I add context:
MIDI is a digital standard for musical notation, one which trackers DID NOT USE. Lots of trackers use their own formats which can't even be opened by other trackers, let alone any MIDI compliant software. Not to mention that MIDI files don't come with samples, while tracker modules had to in order to reproduce a track correctly.
Trackers are as related to MIDI as they are to dots scribbled onto five lines on a piece of paper. All music can be represented using MIDI, because MIDI is just notes. That doesn't mean all digital music uses MIDI. Especially when MIDI doesn't store actual sound data.
Trackers, and I apparently have to say this again, USED SAMPLES. As in, NOT SYNTHS (like the NES). They played back recorded audio data from actual sound files according to a pattern input by the composer. Which yes, you could argue is equivalent to MIDI. But the samples are not, and they are a fundamental part of how trackers work. In order to even get started with using a tracker to create NES/SNES style music, you'd have to configure it with a sample-bank that contains the noises they would make.
Perhaps you are confused because MIDI sound cards did something similar. They used MIDI data to play music using the preset sample-banks that different MIDI cards came with, meaning the track would sound different depending on what sound card was used.
Tracker modules meanwhile came with their own samples, meaning they always played the same. Composers could also use whatever audio files they wanted to create their sample-banks.
"Those old games" also most certainly did not use MIDI, they either had their music produced using direct hardware instruction or whatever tools the game developers created for themselves.
But we're getting off track. You've kept making new claims about trackers, what they are related to, the terminology around them, and what they are for, each of which has been subtly off.
To recap:
Tracker music is tracker music. The word "chiptune" can either refer to a sub-genre within tracker music, or "retro" music in general, which includes lots of other music aside from tracker music. However, it cannot be used to refer to tracker music and only tracker music. Those two terms are not interchangeable. That doesn't change because "it's much later now m8".
Trackers were also not created to "replicate" or "reproduce" anything, they can, but they can also do more. They were developed specifically to take advantage of the new 16-bit sound card introduced in the Amiga, and worked by playing back recorded audio samples, while older computer music was produced by instructing synthesizers to bleep and bloop.
