: It is a data dump of an 8KB ROM from a NEC 78081 8-bit microcontroller.

The ZN-1 and ZN-2 boards used a modular design. A typical game consisted of a main motherboard (which contained the "ic655" chip) and a separate game cartridge or ROM board that contained the game's specific code and graphics. The chip labeled "ic655" on the motherboard appears to have been used across many different games produced for the platform. 78081g503.ic655 not found
