So I'm trying to solder to the original DMG-01's button pcb, and the solder is not sticking to it. What am I doing wrong?

It could be a dirty surface or not enough heat. Apply some flux to the PCB and try again. Be careful with the heat though. It shouldn't take more than 3 seconds to apply the perfect amount of solder.
When in doubt, watch YouTube videos and ask questions here:

My guess is, you need flux. There will be a lot of oxidation to cut through on a 25-year old board.

I don't own any flux at the moment. Do you have any suggestions on what kind I should get? Like the paste, or liquid, or pen, or something else?

no clean flux pen is perfect. Make sure its for electronics.

Hi, Dethoinas, how many watts is your soldering iron ?
And as for the solder, what's written on the scroll of solder ?
And, where do you want to solder on the DMG board?
Maybe we could help you further, i don't think you need flux..
DO you have a picture of your soldering materials, and maybe also of the DMG where you want to solder to?
Thanks in advance, 144Tech

60W 110V soldering iron. But it has a little temperature dial on it and I usually keep it at about 400°C. But it's a sorta cheap soldering iron, so I wouldn't be surprised at all if those temps were inaccurate.
I'm using the solder that came with the soldering iron, so I'm not sure what kind it is. I looked at the product's page that I bought it from and it says the diameter is 1mm and the melting point of the solder is 183°C.

That's good stuff. Flux will definitely help as that gameboy board is almost 30 years old.

Okay, well your sodering iron seems to be o.k , but the tip can be alot smaller (usually such irons are coming with alot of extra tips right?)
If so you could use the hoof shaped tip, and 400c is a little bit hot, maybe you burn up the flowing materials inside the core of the solder wire.
Make sure where you have to solder is clean, you can also use a glassfiber pen, that's like a little brush and you can scrape the pcb blank and clean to bare copper wich makes it alot easyer in certain cases.
However, i like how you try to make the button pcb from a dmg pcb, (i think that's what you are doing, correct me if i'm wrong)
But i would advice to get a nice common ground button pcb on ebay, they go for like 10-15 bucks.. saves alot of work.
Anyway good luck.
