I can't do anything with the cartridge.
It's presumably some custom protection chip, the function of it is currently unknown, maybe it acts as a math accelerator, maybe it does more.
With nothing dumped at all it's impossible to even really guess what it does / doesn't do.
That's another reason these are of concern; if those chips start failing without us knowing what they do it's going to be a problem. Likewise if they need decapping at some point prices aren't exactly going to start dropping.
