Wolf 3D/gs After scouring 5-5 for an hour or so, it seemed best to just try making a Silver Key. (This was the only cheat used to get through Mission Zero.) Evidently, Wolf3D uses two bits in the first block of the Saved Game file to keep track of keys. To make a key, copy your Saved Game for 5-5 to /RAM5. Use Block Warden to modify byte $03B in the first block of the file to ... Gold Key- $01 Silver Key- $02 Both Keys- $03 Change the name of the modified file (e.g. from M0.55 to M0.55k) and write it to your Wolf 3D Saved Games folded. Locations of some other interesting stuff in the first block: Health- $031 Gun Ammo- $033 Max Gun Ammo you can carry- $035 Flame Thrower Ammo- $037 Rocket Ammo- $039 The values at these locations are all two-byte hexadecimal values, lo-byte first. Score is a three or four byte hex value stored beginning at $017. Rubywand ___________________________ There are MANY codes available for Wolf3D if you get stuck Do a search on the web for Wolfenstein 3D cheat codes. I passed the entire game without using codes. (Ok, so I lied. I used the Secret code a few times.) You can: get all guns have full ammo pass to next level become invincible Never run out of ammo get both keys show secrets on the map. You can also get a free life with a cheat code; but, you won't find it on the IBM or Mac versions of Wolfenstein 3D. It is quite obvious and, at present, is the only cheat code I know.
