Indicating that these were affiliate links might have been appropriate, nevertheless the article has provided useful content for me. I have a neglected Nintendo 64 collecting dust in my loft. Being able to play the games I own on an emulator using the original controllers would be well worth the cost of the recommended USB adapter. It didn't even occur to me that I might be able to do this before now.
I was a bit more annoyed that it seems to have been written and submitted just to drive traffic through the affiliate links.
I do agree, though, that the USB adapters are nice. I have a couple of PSX adapters and an SNES adapter. The Japanese console manufacturers seem to do a much better job with input devices than the PC-oriented crowd over here. (Although that could just be personal bias; I did almost all my gaming on consoles and in arcades before the first time I tried plugging something made by Gravis into my MIDI port.)
