Wow, nice! Thanks, I'll give them a try today :D I've been using these codes, but the game freezes and I don't know why.
EARA-AA8Y master code
RFVA-C6TT infinite ammo
AKLT-CA5L infinite tires
AL1A-AA8Y infinite charge for sled
ALVA-AA44 freeze time
R1FA-A6XE freeze loot
I think it also froze with just Master and infinite loot, so I guess I'll try them out individually. Is Master code mostly for emulation, or hardware? I'm currently playing it with emulation, on which it always freezes when using these codes.
Edit: Thanks for checking the final version for the blueprint of the 60's House! :)
Edit 2: The new codes work fine for me :) I ran into only one issue:
Turning off the code and resetting the game will result in a checksum error. This is no big deal, but I should you should know anyway.
Edit 3: Messing around with your codes I got one (AB7A-C8FG) that made me start a new game with 45 Torches, Ice, Tar, Toys, and Marbles :) I'm not trying to take credit for it or anything, I didn't make this, only changed it around a little :P
