Dreamcast. PS3 in close second.
Can you hear it bouncing when you see it? :D
Mine would have to either by the GC because I spent so many years playing on that system or else the Neo Geo Pocket Color because as a handheld it just sounded so happy and bouncy on startup, really gets you in the mood for some Sonic Pocket Adventure, great little handheld if ye never had the pleasure.
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
