I'm a bit reluctant to advertise that I'm doing this, but I'm working on two lists on Deku Deals for arcade titles (emulation and ports)-- one list is everything, the second list may be controversial in that I'm using my best judgment in removing bad emulation/bad ports from the list.
You can get links to the lists, along with a mini-FAQ, at https://docs.google.com/document/d/1qDc ... zY3CJz6JU0
I'm sure I've missed a number of titles, so feel free to let me know if you're aware of anything that slipped through the cracks.
