Ahh, no, forgot all about them... I'll get them boxed up this week, hopefully to ship either over the weekend or early next week.
Still have only found Pac-Man though. Found the Basketball manual, but still haven't found the cart... Ah that's too bad on Basketball, hope you'll find it next time you are digging for something else in there

A COP421 chip, yeah.
But knowing Mattel's early handhelds, they may have plonked the MCU die straight onto the PCB, then it can be harder to dump non-destructively. Okay, found pictures of it... Looks like the die is on the PCB directly, but covered by a plastic cap that looks like it can be easily removed... So maybe...? Many of Mattel's LED games are like that. If all the signals are bonded out, it can be dumped electronically by soldering to test pads or traces. If not, the plastic cap can be removed and pictures taken of the die, and the ROM can be visually transcribed. Buy be careful if you remove the plastic cap- the bond wires are exposed under there and are extremely delicate.

Just out of curiosity, wanted to revisit some games I had mentioned in the past to see if it's possible to dump them (preferably non-destructively)... Pictures are located here: https://www.handheldmuseum.com/Z_Imgs/MESS/CPUs/I think a bunch of them might have weird things written on the chips so it's hard to tell what they really are, but maybe knowledge has increased?
