If it's for android and it's about enhancing graphics for any emulator for any console feel free to join and post anything on those subjects here.

For PS2 I highly recommend a gaming phone , I use a Asus rog phone pro6 has 18gbs of ram and it does a decent job of PS2 emulation using aethersx2, nethersx2, or daemon pro but I don't recommend daemon pro because it cost money and you need to connect to a server for it start a game , so it's not good if you're traveling on a plane.

Games I've played and finish on my phone
Evil dead regeneration
Scarface
God of war 1&2
Bully

And the texture packs work on evil Dead, God of war 1&2 and bully 100%

Hdpacks are for nes I'll be posting samples of each texture pack and hdpacks soon
