Raspberry Pi3 and the
RetroPie setup. Screw all the console emulators that require hacking the system. I've heard that you can use a USB Bluetooth dongle and wire in a PS3/XB wireless controller though I haven't tried it. Plus it has 1080p out. I setup a Pi2 with a wired Gravis Gamepad (and an adapter for N64 games) to see how it would work. It works well enough and a Pi3 is stronger than a Pi2. A Pi3 costs 35$, a case is 10$, a 32GB SDHC micro SD card is 8$ from Microcenter, other parts cost more. Buy your HDMI cable off of Amazon for 6$, it's a digital signal which means it can't get better as long as it gets to your set. You will need a computer to flash the SD Card, but it seems you won't have a problem with that. Check out the link for
Petropie for more information.
If you really want an Emu Station, build a i5 6k computer with a 960 4gb Nvidia card and a SSD to remove load times. Then you can emulate Wii/GC, PSP, and PS2 games at 1080p. I use that. A lot of classics are showing up on Steam now and play even better than emu.
Note that hacking a PS3 right now would be expensive as hell for anything other than PS3 games were you can use an optical drive emulator.
