    Found this awesome bios mod in a random psone. Unfortunately I'm getting a black screen when I power on.

    I assume this is one of those bios mods that enables VCD and cheats.

    Would love to get it to work again.

    Any ideas on where to start?

    All I can suggest is reseating every thing and seeing if it will work - those clips on the boot ROM in particular were pretty flaky.

    The other thing is that if it's like the other internal PS1 VCD boards I've seen you will get a black screen if it's unplugged, since the video is routed through the board (that 6 pin cable near the multi-AV jack) and will be cut off it's disconnected.

    Reseated the clips and re-soldered some bad/cold joints. Did the job! Thank you very much.

    Pretty sure I have 2 of those new in box. When I get home (and if I can find them) I can scan the manual for you
