Maybe Sean can deglob the Soccer cart you sent to see what chip is in there, and we'll know if he can dump the ROM. Assuming the he can, then I'll send the rest of the carts.
It was a ColorVision PCB and a Submarine cart. The pics at Handheld Museum show an identical PCB, but the cart in his pic has the connector fingers on the wide edge, whereas the one Incog sent me has the connector on the narrow edge. The cart just has an LCD panel, so all the games are programmed into the chip on the PCB and some fingers on the connector tell the MCU which cart is inserted. The MCU was an OKI MSM6502 (not the same as a 6502) and I could not see the bits. From the pics Incog linked, Soccer doesn't look like it uses the same MCU as Submarine, but it's definitely not an SM5.
