New User here! Few Questions Odin 2 Portal

ey everyone, I just got my Odin 2 Portal it's my first “high-end” handheld and I have a few questions.

First of all, I saw a lot of people recommending ES-DE to emulate everything, and I’m wondering: is it actually worth it? Does it read ROMs from the SD card?

Second question: any Android game you’d recommend? I currently have Wuthering Waves installed, but I’m a bit worried about the huge storage size of games like Genshin, Star Rail, etc.

Last question: is there any way to enable rumble? I set the vibration strength to medium, but I’m not getting any rumble in any game I’ve tried. I also tried streaming with Artemis and Apollo, but still no rumble at all. Any suggestions?

Thanks everyone for the help!
