      Pi Model: 3
      RetroPie Version Used: 4.1
      Built From: Pre made SD Image on RetroPie website
      USB Devices connected: Keyboard / Mouse
      Controller used: 8BitDo SFC30
      Guide used: Main wiki & Help Separating PC Engine & PCE-CD

      I am a bit confused on NES emulation. I previously loaded NES roms onto the retropie and was able to play them (I don't recall the set I used) but I would like to try some rom hacks and translations however I can't get them to load. I've tried patching No-Intro Roms, I've tried patching goodtool roms, I've tried to load unmodified No-Intro & goodtool roms but none of the new roms work. Is there a special set I have to use when playing NES roms?

      I'm using nestopia as the emulator.

        The patching utility should let you know if the patch was successful after it runs. Are you having trouble with all NES ROMs or just patches? If it's the latter, is it just one patched game, or several?

          The previous games I uploaded to the retropie still work. I have no problems running them.

          I've tested several hacks and translations on my PC using nestopia to verify they are patched properly and they work just fine but when I upload them to retropie and try to play them, the screen turns black for a couple of seconds then comes back to the rom list.

            Launch one of the offending games and let it fail, then post the contents of /dev/shm/runcommand.log.

              This isn't one of the translations or hacks but it is one of the new games i downloaded which works in nestopia on my PC but not on retropie.

              The folder you pointed to only contained three files which are outlined below.

              retroarch.cfg
              video_refresh_rate = 60

              runcommand.info

              lr-nestopia

              runcommand.log

                Nothing seems to stand out in any way there. Try doing the same thing, only this time invoke the runcommand window during launch and select "Launch with verbose logging". then post the information again.

                  @mediamogul I'm going place my bets on headers (or rather a lack thereof.)

                    Seems like I had that same problem a few years ago.

                        @speciallt1212 Please see https://retropie.org.uk/forum/topic/3/read-this-first regarding posting logs (use a code block or external site). - markdown info here http://commonmark.org/help/

                        Your rom probably doesn't have headers - you need nes roms with headers.

                          @speciallt1212 My best bet would be to search/get help at www.romhacking.net

                          As @BuZz said this sound like you have applied a patch to a rom that don't have a header. Therefore creating the problem of the rom not booting up.

                          Get a clean no-intro set for your roms.
                          Stay away from Goodsets and the likes.

                            I'm still not sure what's going on. It seems like any new NES rom I load onto the retropie experiences the same issue. When I say new I mean any rom that wasn't already previously loaded on the retropie before I started to experience the issue.

                            I downloaded a fresh set of no-intro roms and verified they were correct using clrmamepro. I compared one of the currently working roms [Addams Family, The (USA).nes] to one of the ones in the new set I downloaded i.e.

                            Addams Family, The (USA).nes

                            CRC32: 94A230A9
MD5: 56DF8432043A2D724BAB64FEB39912D5
SHA-1: 7E236610BDFDE5A439A19E18C873982E2C607643

                            Everything matched so I know I'm using the correct set of roms.

                            I then tried to add a new rom from the same set [10-Yard Fight (USA, Europe).nes], however this rom won't load, it experiences the same problem as the other roms I described in my earlier post i.e. the screen turns black for a couple of seconds then comes back to the rom list.

                            10-Yard Fight (USA, Europe).nes

                            Any ideas on how to fix this?
