Shift+Control+B (in the Polish version), then klapaucius/rosebud from The Sims and you could do rosebud;!;!;!;!;!;!;!;, it would error out because of the trailing semicolon, but still add money to your account, so you just held down Enter until you were satisfied with the amount of cash in your account

Flying car cheat in San Andreas. I don’t know what the buttons are, by my muscle memory is so ingrained that if I start it I can usually get it after 1/2 attempts. Even if I haven’t touched the games in years.

San Andreas Max Health + $250k. Saved me in the warehouse mission in Las Venturas lol. I hope I'm getting this right:

R1, R2, L1, X, LEFT, DOWN, RIGHT, UP, LEFT, DOWN, RIGHT, UP

Porkcharsui in the original pc version of Grand Theft Auto. If you named your character this, you had an overlay with coordinates so you could find your way easier, you'd get all the guns and the possibility to toggle a kind of sped up mode.

Oh and howdoiturnthison in Age of Empires 2 to get an AC Cobra with machine guns

I had San Andreas on PS2 as a kid, only played it on PC a little bit as an adult; but, the fact that you type the cheat codes on a keyboard means they kinda make words, so i forgot the PS2 ones and i remember some PC ones.

Ratchet and clank 3, the cheat code is told to you in a cutscene:

"Aren't you going to unlock his secret costumes? Here, I'll put in a cheat code. Up up down down left right circle square square... Haha! Look! He's in a tutu!"

Call Cousin Vinnie

It gave you a boatload of money in SC3K

Surprised nobody mentioned "motherlode".

Something like 50k simoleons in The Sims 2. Absolutely essential to any save file.

prince.exe megahit

Warcraft 3 - whosyourdaddy (makes your units invincible and one-hit every enemy)

Triangle triangle square circle X L1 L1 down up

Spawns the Hydra in GTA SA

the first 'cheat code' that came to mind here isn't for a game:

Select • Play • Select • 30 • Select

BARACUDA for level select in Sonic 3D Blast.

Alternatively, CALLACAB for Vector Man.

Doom had IDKFA that just basically gave you all the weapons and keys. I was a pretty young kid when that game was popular and all I wanted was all the guns.

It’s not a code, per se, but the method to get unlimited money on SimCity for SNES is forever in my brain. (I didn’t always use it but sometimes, I just wanted to make a cool city and not do the tax and budget stuff.)

As others have already mentioned, IDKFA for Doom and didn't it work in Doom 2 as well?

I only ask because when ID Software released Heretic, a swords and sorcery style Doom game, I remember typing in IDKFA, expecting the same results. It was the Doom engine after all. Except typing in the classic code kills you instantly!

Another isn't strictly a cheat code. On the old 8bit computers the UK, you could enter some programming code to change the memory before loading in a game. (This is over simplified.)

Because of the altered memory, it would effect the game in some way. E.g. infinity health or lives.

I found a listing in a magazine which you could type in to help with the ZX Spectrum version of Batman: The Movie.

In this platform game, with the cheat, when a bad guy tried to climb a ladder, they would freeze.

This was very helpful and worked wonderfully all the way through the game. That was until you reached the very end whereupon the Joker was on a rope ladder attached to a helicopter.

The code interfered with the end of game boss in a way it wasn't expecting and the game would crash.

Thanks.

MADEMAN <- all weapons gta 1

Skitchin

At the warning screen, B A Down A Start Start (Spells BADASS)

Activates cheat mode, and then you can use the password screen to input cheats. But the only one I used is MONEY which starts you with 10,000 dollars or something.

Rocketman - GTA San Andreas

I remember the cheat but not the exact game lol. Definitely Sega Mega Drive though.

ABRACADABRA (R for d-pad right, D for d-pad down).

Going by a Google search it could've been Vectorman or Ecco 2. Or both because I played both a lot back then.

I wasn't particularly wowed by the gameplay of the sims 4, but I really enjoyed the building mode, especially with the freedom to put stuff exactly where I wanted, collision and autosnapping be damned.

DULLARD 😅

Also a bonus code I won't forget:

ADE-NAI-WRA-LKA

You can all guess what games they are from.

Sega Mega drive from when I was 3-4 years old.

Sonic the hedgehog - unlock all levels cheat: Up down left right A Start (twice)

Minecraft: Open to LAN -> allow cheats
I really thought I discovered a massive bug with that one when I was little lmao

Star Wars Battlefront II PS2 invincibility:

Pause

Hold L2/R2

Up, up, up, left, down, down, down, left, up, up, up, left, right

tuck tuck tuck and arrrrwalktheplank are two of my favourites. The first summons a monster truck in AoE3, and the second has a large pirate ship jump into the battle in Free Space 2.

Actually there is a set of missions in FS2 that can only be reached by cheating to become invincible during an event you were supposed to die I think.

I find it neat when companies put in assets and extra content most players wont find without trying to break things a bit.
