When cfw for ps3 came out you needed either a ti-84 calculator or an iphone to put the firmware on the console. I had an iphone so installed ubuntu on my pc so i could dual boot ios and android on the phone then replace android with the cfw. I never even knew there was anything but windows back then.
Get an ir usb receiver like a flirc and just use a normal remote. I think flirc even sells a remote.
