herc's adventure, can anyone help

[GHS]

Hi, I am new here, and I was wondering if anyone can help me out.
I am making a map of PS1 Herc's adventure for VGMaps.com. I am mostly finished except for some areas that I cant get to. I need a cheat engine and codes to pass through barriers. I am using PSX1.13 emulator to map the game.
Can anyone help?

Moved your thread to appropriate forum, but what region game is it for? I know it's PSX but we need a region or better yet the serial number of the game so we can make proper codes for that version.
