Welcome back!
Something like this? https://upload.wikimedia.org/wikiped..._PS2_hiiri.jpg[...] and PS/2-style controller [...]
I realise you're referring to a PlayStation 2 controller, but I couldn't resist. 'PS/2' usually refers to the keyboard and mouse ports ( https://upload.wikimedia.org/wikiped...Ps-2-ports.jpg ), in case my joke isn't making any sense (or, going further back, the 'Personal System/2' from IBM).
I have mostly played using the keyboard (and to some extent, the mouse), but these days I also do use an official DualShock 2 controller, with a converter indeed. Could recommend, if you like that controller at all.Also, I like playing with a PS2 controller. If anyone out there is using one, what do you recommend? I've noticed that on Amazon there are PS2 to USB converters, so I'm thinking about buying one of those and using a genuine PS2 controller rather than trying to buy a crappy USB PS2 controller rip-off. Thoughts?
As for the resolution, I have never even seen such devices live, and with that aspect ratio, I can only suggest you try some different ones out, and see what you like the best yourself.
Note that, in addition to the resolution (set via the config utility), you can change the aspect ratio in game as well.
