So, I want to use my handheld for more than a music player. Need recommendations for systems to to gen 4 + GBA
Mainly games that aren’t too complicated but anything is fine

Those are all mature systems, and I’d say that rankings for games on old systems are reasonably consensus at this point. You can just search for “best system whatever games” and get lists, look for games in genres you like; I’ve had luck doing that in the past, as that avoids a lot of the chaff.
I personally probably have gone back and played Super Metroid the most on the SNES, but depends on what one likes. If you like RPGs from that era, different set of games.
For this ranking of SNES games, as an example:
https://www.ign.com/lists/top-100-snes-games/92
I’d say that probably those games are going to cluster near the top of any list of SNES games.

The “/v/s recommended games” wiki is mostly maintained by 4chan users (yuck), but it’s been a good source for both mainstream and hidden gems.
If I have time later I’ll edit this with some personal recomendations.
What do you consider “gen 4”, because I’m guessing we may not be thinking the same if you consider the gba “gen 4” era.

If he means “4th gen and GBA”, that’d work.

That has it as Genesis and SNES era.
I guess Mortal Kombat, Golden Axe, and Streets of Rage on Genesis, and Mario RPG on SNES. Not a lot of games that standout and hold up. There were a lot of games I played on my Genesis, but there were better games in previous gens and afterwards.
They said gen 4 and GBA. 2D platforms that’ll run on a cheap emulator handheld.
Some good ones I haven’t seen mentioned:

SNES:
Sunset Riders and Wild Guns are fun little western shooters.
Genesis:
Rock’n’roll Racing is a fantastic racer.
GBA:
The Wario games are pretty superb for quick sessions
Kirby: Nightmare in Dreamland was my absolute favorite GBA game as a kid. It’s extremely linear but so well put together
The Pokémon Liquid Crystal ROM hack, a gen 2 remake for GBA
That looks awesome. I might switch over to that version, or at least give it a try
I tried it and it’s awesome. I like it better than Liquid Crystal. It feels way more retro but also modernized at the same time. The 60fps world is a huge improvement
I really like Donkey Kong Country as a kid. Great environments, fun platforming and a timeless soundtrack.
On GBA my most played game became an underated licensed gem: Lord of the Rings: The Third Age. The GBA version is completely separate from the ones on other platforms, but it’s a great turn based strategy game in which you get to command the heroes and other units through all important battles of the original story. Really fun!
