This code is better than the other code I made because it allows you to fly through the top of the stage and loop around and it fixes a small problem in the bonus round where there is a small invisible block to the right of the screen. You also might want to use the no drown code and no fish codes in conjunction.

Also, my better control code has the opposite in the bonus phases. I'll work on that tomorrow and some other codes.

Balloon Fight.nes

Disable collisions (affects all players and enemies)
PNSTZTAX

SAESPTSZ

Stars fade in and out
AKVSAIPS

No Stars

The convert Game Genie to Codebreaker format converts as invalid under the code converter tool for the main site. I have no problem doing this manually but others will run into a wall at some until this is fixed. Just giving word that this needs to be fixed.

Please report this to Rimsky82 to have him fix it.

because Codebreaker does not do (game genie) ROM hacks
this is why is invalid

This was the impression I was under when I was working on the system. Are you just looking for the raw interpretation of the code, or is there another reason the codebreaker device should interpret ROM hacks?

[lee4]

I assuming Codebreaker always been RAM based cheat device.

if I not mistaken

my past experiences I never seen ROM hack code on Codebreaker for GB/GBC/GBA

[nensondubois]

Codebreaker handles both ROM patches and RAM hooking. The ROM format is different than Game Genie and the RAM hooking is different than Gameshark.

[lee4]

are you talking real codebreaker or emulator?

[rimsky82]

Assuming the codes on this page work, he's right. I see codes there that write to memory where ROM is stored.

I'll get that fixed then. I have also ordered a GB Codebreaker for myself for testing since all I have are Gamesharks.

[nensondubois]

The format is this:
XXYYYYZZ

XX = ROM Bank/RAM Bank
YY = Memory address
ZZ = New value

I have two Codebreaker units and have tested several ROM patch codes and they all work based on this theory. Some games still need to hook the main VBLANK and in some cases require additional patch codes to work with specific games. Super Mario Bros. Deluxe requires a patch code and its included in the Codebreaker's factory default listing. I should get around to posting pelican's codes also, or someone who has more time.

There is an included Shark code converter built into the Codebreaker and it converts Gameshark codes to the CB format.

[rimsky82]

I was pretty sure it was XXZZYYYY, and the gameshark is the same except the address is byte-swapped. (endianness)

[nensondubois]

That's definitely not the Codebreaker format.
