      @simonandrewwil Also, when you say "20% slower" can you clarify. Do you mean frame-rate, audio, input lag...? That could mean a lot of things.

            @jonnykesh Fame rate is fine, audio and graphics are slower the game I am trying is GBA advance wars as my bench mark. The game just crawls.

              @simonandrewwil So it's not just SNES then? Have you enabled any sort of over-clock on the Zeroes? As Hex says above, not all PIs are created equal.

                  @jonnykesh no, its most noticeable with the SNES and GBA emus.

                    @simonandrewwil So, no then. Worth remembering in some older systems the European versions would run 20% slower due to the difference in the 50/60 Hz electricity system. Try going into the settings on a "slow" version and setting region to US.

                      @jonnykesh its the same image, the settings should not be different. The advice about the difference in chips sounds like that could be worth looking into. I will have a go at overclocking in the config menu. Some great advice. Thanks guys.

                        @simonandrewwil Silly me. I forgot to mention I am using a mixture of pi zeros and Pi zero w's. Guess What? The pi zero W's are the ones running slower. I have just figured this out. Doh! Why is this? Is it due to to wifi/Bluetooth running in the background? The pi zero image was running a wifi dongle with no big processor hit.
