Tengai Makyō Zero

Fourth game in the series, with the English title “Far East of Eden Zero”. Somewhat unique hardware. 40Mbit Cartridge (32+8MBit). One of 3 Hudson games to make use of the Epson SPC7100 decompression chip. This title specifically uses the SHVC-LDH3C-01 variant to provide a real-time clock. Game contains calendar function to keep time and adjust seasons in game accordingly. The only other title I’m aware of to use a RTC is the sequel to Hudson’s Daikaijyuu Monogatari that used the S-RTC chip.
