I have a feeling the non-MCU ones with ASICs might end up being a catalyst for people writing netlist style simulations of custom chips like that too assuming high enough resolution images can be produced as from the ones we have seen images of so far they look relatively simple compared to some of the others we've seen so might be a good starting place.

As we've found with various protection devices, not every single one we've ended up seeing decapped is an MCU, some are custom ASICs similar to those found in some of the handhelds (in the case of Jaleco's protection device used on some games, it actually likes like some 7-seg driver ASIC repurposed as a protection device)
