advices for emulator games??

If you're a fan of the 2D Pokémon games I recommend checking out some of the modded fan games. They can have different storylines or include later generations of Pokémon and moves added into earlier games.

thank you very much, but I don't really like Pokémon, if they're just 2D indie games that have nothing to do with Pokémon tho I will check them out

Are you an iPhone or Android user? If you're an android user, give citra a try! I think the 3DS has a cool selection of games even from my experience. I've enjoyed the majority of mario titles and also tomodachi life. I'm not too into the indie side of games however if that was what you were looking for  

thanks!!! 

any gameboy (original, color and advance) and ds game

i don't know what emulators are available on apple but the ones i use that are also available on android are ppsspp, vita3k, duckstation (ps1). 

psp games i recommend -

• hatsune miku: project diva 2nd (rhythm game with vocaloid songs)
• persona 3 portable (half visual novel half dungeon crawling jrpg. story is super good), 
• persona 2 innocent sin (older style rpg. battle mechanics can be hit or miss, but it's one of my favorite games of all time. not connected to other games in the series, except that it's the first half of a duology, second half is persona 2 eternal punishment (but that one needs an english patch))

i haven't played a lot of ps1 or vita games but there's a lot of good titles on em if you look enough lol. the psp and vita have a lot of visual novels so if that's your thing you could look into that.
