Some codes I made.

[MathUser]

Here's the codes as I added them in Mednafden:

[644c2c3cf2dc2e3fce741844e497a18f] Aladdin (GB Color) [C][!]
R A 1 L 0 0000CC50 63 Inf Apples

R A 1 L 0 0000CC12 09 Inf Lives

R A 1 L 0 0000CC6C FF Inf Energy

[89bb0d67d5af35c2ebf09d9aef2e34ad] Donkey Kong Land (U) [S][!]
R A 1 L 0 0000C65D 01 Always Have Partner

R A 1 L 0 0000C613 FF Invincible (Blinking)

[6e30394fd7ef4a4dc3fe1edd9fc69f72] Donkey Kong Land 2 (UE) [S][!]
R A 1 L 0 0000FFAA 09 Inf Lives

[8ed4304e943b553f8ff3abc1e66ea91e] Aladdin (GB Advance)
R A 1 L 0 030005CE 63 Inf Apples

R A 1 L 0 030005CA 09 Inf Lives

R A 1 L 0 03004CD0 FF Invinicibility (After Hit)

R A 1 L 0 030005D0 63 Inf Gems

R A 1 L 0 030005D4 01 Have Parachute

===============
Here's their proper conversion for use on other things (I think)

Aladdin (GB Color)
016350CC Inf Apples
010912CC Inf Lives
01FF6CCC Inf Energy

Donkey Kong Land
01015DC6 Always Have Partner
01FF13C6 Invincible (Blinking)

Donkey Kong Land 2
0109AAFF Inf Lives

Aladdin (GBA)
030005CE:63 Inf Apples
030005CA:09 Inf Lives
03004CD0:FF Invinicibility (After Hit)
030005D0:63 Inf Gems
030005D4:01 Have Parachute

I'm not sure if the Aladdin GBA codes are in Codebreaker format or not. Long ago I had a utility to convert VBA codes to CB format but don't have it anymore. I know it was easy. I think you just add a 8 or 3 to the front of the code in place of the first value? Not sure tho. Someone else can convert it.

Yeah; for CBA just add a 3 in front of the address for an 8-bit write and an 8 for a 16-bit write.

Aladdin (GBA)
330005CE 0063 Inf Apples
330005CA 0009 Inf Lives
33004CD0 00FF Invinicibility (After Hit)
330005D0 0063 Inf Gems
330005D4 0001 Have Parachute

In Mednafen I guess you can ignore the first two numbers of the GB/GBC gameshark codes. They should stay zero. At least thats how I got the codes in Aladdin GBC working. They wouldn't work if I tried to use add 01 anywhere. I edited my post to show what the codes should look like in Mednafen.

So, is there any reason why these codes haven't been added to the site yet? Also, dunno if you guys noticed this, but these code descriptions aren't in english:

Here's a mednafen code I made for Capcom VS SNK NeoGeoPocket

[dfea3ad9af4a631de6f97d86589b971e] SNK Vs. Capcom - The Match of The Millennium (W) [!]
R A 1 L 0 00004961 30 Infinite Energy

It'll get you past the game at least. I can't figure out how to get Mednafen to open aside from dragging ROM's on it. But it won't do anything if I drag lynx or turbo grafix cd games onto it so I can't make the codes for those that I wanted.

The code will work on wii mednafen too.

Didn't know someone else was making those codes. Oh well.
