Hey there Shadowscale and welcome to PokeCommunity.
Though it's sad to hear that you sold your other Pokemon games, it's also great to know that you're coming back :D
I actually had a similar problem with my mom, I was not allowed to buy video games so I secretly bought a GameBoy Color and Crystal version around 5-6 years after they were released
Like you, this one game caused me to be engrossed in the world of Pokemon.
Since you are currently playing Black 2 or White 2 (I assume), check out the Black 2 and White 2 forums for any help you need and discussions.
By Chiptune are you listing an artist? Or do you mean 8-bit music?
