Ok let's wait for the rescans so you can align JR55 properly. Why does ML102 need to be redone? It's only 1 layer and the scan was good quality.
It's not strictly needed for emulation, but I think it's a good thing to have the full pieces preserved and at hand. That way, they could even be theoretically used to restore old faulty systems, just like MAME's non-trimmed ROMs.
Also, I don't think that anybody is going to go through disassembling and scanning all these handhelds in bulk like this ever again, so it's the perfect time to have these things properly documented.
