Chess King (Watara Supervision Lookalike)

[Ankos]

A while ago I shipped out a handheld I bought to get its internal ROM dumped. It came with a cartridge as well, though the individual(s) I sent it to have not been able to dump that yet. The handheld was broken at the time I got it, so I don't really know how it is supposed to work. Anyways, here is the ROM and some pictures of the machine. It closely resembles a Watara Supervision. I posted this stuff on the BGC Discord earlier, but have decided to post it here as well

Oh, and here are some pictures of its internals
Edit: Added ROM for Dictionary. Looks like this machine is getting support in MAME

Ooh, cartridge based.

Do you know of any other carts that may have been made for it?

I do not know of any other cartridges for it
