SimCity SNES (USA) codes

[darkmoon2321]

I've got some new codes for SimCity for the SNES. A couple of these will fill requests that I saw on the game's code page:

Max Land Value (Works for the important zones, although some I zones still have low value)
039DA8A5

Maximum Police Coverage (Does not actually reduce crime though)
039F86A5

Zero Crime
039F26A5
039F2900

Max Pop. Density and No Pollution (These two variables are related, so they must both be changed)
03A094A5
03A11AA5
03A11D00

Build anything anywhere (You can build over other zones or water. You can't bulldoze water though)
01BA8380
01BA8444

Thanks to BluArtistEyes who pointed out where to find the police coverage table in the RAM. I used this information to help locate patterns in how the game accessed and stored data to this table as well others. I'm new to this site, so let me know if I formatted anything wrong. I didn't see how to input the codes into the database myself, so I figure I would post them here.

Here's a couple more, in response to requests on the game's page:

Approval Rating 100%
7E0DDF64

Disapproval Rating 0%
7E0DE100

Also, I hadn't noticed that Ugetab had already discovered the code to give power to all buildings. Apologies!

I have plenty of codes for other games as well. All codes I post are in RAW, unencrypted format.

Donkey Kong Country(USA), SNES, RAW:

Mid-Air MultiJump (There is a slight lag before the first jump, but nothing too serious)
BFB925:29
BFB924:80
While there was a code already listed to do this, this version only uses two lines of codes instead of four.

8086C2:15

I've also identified RAM addresses used for Int-War-Chm, number of soldiers, ruler stats, city stats, and so on. I could post them, but there would be over 1000 codes, and they apply to different officers/rulers in each scenario. The city stats apply in each though. While it is pretty straightforward just to do a code-search for these types of things yourself, I will post this information if there is interest.

One more for Donkey Kong Country (USA), SNES, RAW:

Here are a few codes in response to requests from terpsfan101 for Zombies Ate My Neighbors (USA), SNES.

Invulnerability (Immune to damage caused by coming into contact with enemies, immune to Big Baby's stomps, immune to Jelly Blob's slime shots. However, this code prevents access to keys and consumable items found on the ground. It also prevents you from exiting the stage, so you will need to turn it off when not in danger. Saving victims still works fine.)
80F7FA:80

Less Points Required for Bonus Victims (Changes requirements from 40000 points to 20000 points. There are two codes because one affects the initial points requirement, and the other affects every bonus victim thereafter)
808627:02
82D472:02

Always Extra Bonus Victim
82D45E:80

Always Extra Bonus Player
82D45E:80
82D483:80

Invincibility Plus Keys (when you get hit or use a weapon, you get a key instead of taking damage. Must turn off to exit stage).
80F7F7:A9
80F7F8:21

Added you to the Hacker Group so you're able to add your codes to the site instead of waiting for someone to have free time to add them.

I loves SimCity games on SNES version! And now, I still enjoyed DS version of SimCity games!
Anyway, thanks for the nice codes!
