    hi,
    sounds like a (compatibility?) problem with your n64. If pal games are working, the everdrive seems to be ok. If you have the possibility try your everdrive with a friends n64.

    greetings, saturnu

    I would first try different roms first. And then what is the crashing? If your TV doesn't support 60 hz resolution it may black screen (or show black and white picture).

    Change the tv and retry the roms if possible.

    i tried several roms in the -version. in most cases the first screens work, but then it crashes. all pal versions work fine. it's a pal n64.

    it does not depend on the tv. other consoles or even the z64 worked flawlessly in 50hz and 60hz mode. besides, when the -versions are crashing, the sound disappears. the n64 light stays red and the ed64 red is always turned off (i don't use a case for the pcb and in pal games, the red light of the ed64 just seems to flash when something is loaded.

    it's similiar to this here:

    but i alrady changed the sd card.

    i really don't know what to do, i sold the z64 to get the ed64 to play goldeneye:x unfortunatley goldeneye:x can only be applied on a version of perfect dark.

    please help me

    That's a save file. It might not work on the pal game.

    how to recognize which version it is?

    ok, i see. but that is more important to me:

    i tried several roms in the -version. in most cases the first screens work, but then it crashes. all pal versions work fine. it's a pal n64.

    it does not depend on the tv. other consoles or even the z64 worked flawlessly in 50hz and 60hz mode. besides, when the -versions are crashing, the sound disappears. the n64 light stays red and the ed64 red is always turned off (i don't use a case for the pcb and in pal games, the red light of the ed64 just seems to flash when something is loaded.

    yes i know ^^ often the game have a 'repair' function after that it's working.
    i have to check if there is a chk-sum to fix, beside just skipping the dexdrive header, obviously that's just not enough :D

    edit:
    i think i know what's going wrong.

    many dexdrive-n64 files have a nearly empty (corrupted) mempak-header
    - maybe they are created with emulators and not dumped of a memory card

    [dexdrive-header (5Kb)] [[missing-data][mempak-content] (32Kb)]

    so if i just skip the dexdrive-header the mempak-header is still corrupted
    [[missing-data][mempak-contant] (32Kb)]

    after the game fixes the header the savegame is working again like normal
    [[mempak-header][mempak-content] (32Kb)]

    as a workaround you can try to use the mempak-features of the controller plugin of project64:
    - dump the mempak -> copy it to the pc
    - extract the note of the downloaded one
    - insert it into the dumped one
    - copy the modified one back to the sd

    the goal is the keep the right header (added by the game) and just add some notes
