Ganbare Goemon: Yukihime Kyuushutsu Emaki
© Konami 19/07/1991 -- ¥?
Also Know As: The Legend Of The Mystical Ninja (US, SNES 1992)
Gradius arcade game (1st level only) is the game Warlock Zone III Amusement Park
You will require the Snes9x.com emulator to use the save games also with the game.
I used the excellent 'Snes9x for Windows 95 or above, v1.39' and the games play fine.
The ROM zip file contains a save game with Goemon outside The Game Center, to use this save game load the game in the Snes9x emulator and then press F1 to load the save game.
