Hi ! Quick question, I wanted to start emulation on my steam deck (dolphin for GameCube and gba emu), however I apparently need a usb driver to transfer roms on the deck. Is it possible to download these roms on internet and skip the USB driver step ? If yes, can you give me some clues about how to do it ?

Second question: is it possible to play with friends on local or online to these games (MK double dash for example) ?
