      I patched the v1.2 rom by accident at first and it resulted in a white screen as well. After patching v1.0, everything's good as gold on my various systems, including the GBC system entry of Emulation Station launching lr-gambatte. My file extension is .gb, but I really don't think it matters here.

      Edit: I just checked the es_systems.cfg file and if you plan on adding it to the GameBoy Color system of Emulation Station unzipped, the extension should indeed be .gbc.

        Yup, extension doesnt matter, just so long as you set Gambatte to open both .gb and .gbc (in vanilla retropie, they are different "systems" but the same emulator runs both).

        White screen on both pi and PC is 100% bad dump.

          Did you rename the patch the same name as your rom and check the crc32 of the Super Mario Land 2 ROM you downloaded because I had the same problem at first.

            @mediamogul I have the 1.0 version, or at least that's what the rom is titled. I haven't been able to find another 1.0 besides this one.

              @SammyBoy and @Capeman's mention of checksums, or crc32 is going to be key here. The v1.0 ROM used is listed here as being d5ec24e4.

                I got it working. The rom file I had was bad, even though it said 1.0 and site said it was a verified good dump. Thanks everyone for the help.

                  Where did you find it and what was the file type?

                      Between this and your previous help requests lacking any system details, you really need to read the following two links to avoid noted trespasses around here.
