rom dumping

[Gameguy]

checked all the pins before i desoldered it and they all checked out fine, no it is not a tengen game, its ariel the little mermaid

If all the traces on the board are working then the problem isn't with the board. I'm assuming you cleaned the connectors on the board already. If it's just dirty or your console is dirty then that could be a cause too.

if i cant figure out how to dump the rom i am going to buy a repro board and just transfer everything over

If it's an original game then it's usually better to use a cheap sports game as a donor so everything is original OEM.
