Info from MameC: There is an MCU "PISCES" that is either a NEC uPD78322 (with 16K internal ROM) or NEC uPD78324 (with 32K internal ROM) that's used for protection. The MCU needs to decapped and have the ROM read out. This chip is a 16/8-Bit single-chip Microcontroller of the 78K/III series CPU and currently doesn't have a CPU core for MAME. There is partial simulation of the MCU but the game will not really be playable until the chip is decapped, decoded and a core written. Info from Haze: Gals Panic 2 is 2x68k, protection mcu handles the communication between the cpus so it doesn't work. Update: The MCU needs decapping and dumping. Ogoun reported some limited success decapping an MCU of the same type from Brap Boys / Shogun Warriors a few months back, but thus far we haven't seen any imaging of said MCU, and don't have a CPU core for it, so no progress can be made at the moment. If the MCU on those is successfully decapped, imaged and emulated then the chances of the MCU on Gals Panic 2 being done increase greatly (as it appears to be the same type of chip, with different internal ROM)
