you do right mate. Highly recommend wreckfest if your into burnout style games.

give that a read, or watch his video with step by step instructions. If you havent ordered already, you'll want a Micro SD card (A2 class) depending on the quantity of emulated games you plan on putting on - I personally went for a 256gb as it was plenty for me.
or
if your a lazy bastard people sell micro SD cards with Batocera installed (its like an emulation suite, fully integrated onto an SD card) loaded with loads of games. I've seen a few on FB marketplace, like a 512gb card with games & fully set up for around £70. the card alone is probably £40+ so your paying extra for the premium of someone setting it up and installing a load of roms to it. I personally didn't as it was packed with roms I wouldnt play. but its an option anyway
