    AM29F400BT as bios replacement - MV1C

    I was watching a Youtube video about those chinese CMVS and i noticed that it uses an AM29F400BT as a Bios instead of a normal Bios or a NeoBiosMasta adapter. Is it safe to use one of those? Is it a direct swap? In the video in question you can see that the first and second pins were lifted...
