I emulated a lot of PS2 & Dreamcast on my LCD deck, but haven't bothered since I got my OLED.
What I want now more than anything is to play some Bushido Blade on that thing. I should stop being lazy and throw 1 & 2 on there.
Emulating anything before Dreamcast seems like overkill, but I guess there's a handful of N64 games I wouldn't mind revisiting.
