[I had responded to the rest of Dekkadeci's post first, but it turned out to be useless due to the confusion hopefully cleared up below.]
If what you mean by "rip" is YouTube video, then I apologize. My understanding of the word "rip" is that it means any attempt at transcription or rearrangement that does not involve simply recording the audio from the game.
Okay, I should have read this before. That explains the confusion.

Here's some info!

A rip is data copied from another medium, such as a cd. In this case, the rips were done from Game Boy and Game Boy Color cartridges. This is generally more reliable than recording from the console, because when you are recording, you might also record static, or have sound effects obscure the recording, or just have poor equipment, etc. You mentioned nsf: this is a format for NES and Famicom rips. NES rips are almost always accurate, in my experience, as long as you get them from a reliable source (eg. Zophar's Domain). So are Game Boy rips (gbs), which is relevant here. Of course it is still indeed important to check against the original console, as for example, all rips you'll find of The Smurfs for Game Boy are in mono, while in the game there is an option to have the music play in stereo instead. Note that ripping is only reliable for platforms that have a sound chip. It is very hard to rip GBA games, and when you do manage, the result often ends up sounding slightly different (mostly higher quality) than it does in game. This is because the GBA does not have a sound chip, and sound is managed by the CPU.
If your arrangements are accepted, it seems likely that mine would too! Especially because you also use slowing down of the video.
It could still be that my arrangements are too accurate, though. You mention arrangement choices, but I don't have to make these in this case, as I'm arranging tracks that can be played on piano with two hands without leaving out any notes (except the percussion on tracks that have it), so it's probably more of a transcription than an arrangement.
