Golvellius Vallye of Doom (Master System) CIB

Maou Golvellius (魔王ゴルベリアス, lit. ”Devil Golvellius”) is an action role-playing video game developed by Compile and originally released for the Japanese MSX home computer system in 1987. Later that year (1988), Compile released yet another remake for the MSX2 system, titled Shin Maou Golvellius (真・魔王ゴルベリアス, lit. ”True Devil Golvellius”). This game featured mostly the same graphics as the ones in the Sega Master System version, but the overworld and dungeon layouts are entirely different.
