I don't have pictures to show, but I will do my best to describe it.
It came with a PC Engine Duo I purchased from the forums. It's the same grey and blue design of most PC Engine Duo controllers, with a few differences. Firstly it says PC Turbo in the top left corner instead of whatever it typically says up there (I'll assume NEC or PC Engine), the d-pad is much more traditional as in it lacks the circle style and in fact looks almost (but not exactly) like a repainted Dreamcast d-pad, and lastly the middle part which usually has a logo is just entirely blank like many of those cheap replica controllers you can buy online for many consoles.
It seemed to work fine at first, but then I played games that required diagonals. For the longest time I thought I had a 1st party controller and was blaming Fantasy Zone's controls on a shoddy port... until I saw Game Sack's review of the game on the TurboGrafx-16 and they didn't bring up the controls once.
So my question is... does anyone own or know anything about this controller? If so what's the quality of the d-pad like in comparison to a 1st party controller? I haven't actually used one, so I'm not sure if the issues I'm having with diagonals are the same across the board with original controllers as well. Thanks.
