That's awesome! Ah, the TUV. Fortunantly we don't have that here yet. I hope you recieved everything in good order today and wish you a lot of fun installing and driving!
If this is serious i'd be okay if the simulation suddenly stopped right now. And i'm afraid you are serious. At this point it just stops making sense to me.
I have the Anbernic RG35XX and so far it has been an amazing device which I never regretted buying. You can get it for around €50 from Ali. The one linked seems to be a knock-off because I don't see any Anbernic branding.
