hi, i'm new here and i don't really know what i'm doing. i'm finding many resources on how to build a mame cab, but what i want to know is, is it possible to not connect to a fixed monitor? space is a premium in my house and i don't have room for a cab, looking for something small and portable that i can plug into my tv or take to a mates and plug into his, i'm picturing a compact black box, like a games console, but is that even possible? if so what do i need to make it component wise? also the least amount of software fiddling about the better, so if i take it around a friends house how do i make sure it'll run on his tv? in terms of aspect ratio and screen size and things like that. thanks for any help, it is appreciated.
