Code Errors

[Whipon]

1. All codes in all my posts published after your note about the ROM versions in post #10 are tested only with original ROMs [!], but I forgot note this in my posts #11 and #12.

2. Thank you for that you repair your own codes and they already works properly.

Also, your code for Super Mario Mario Bros. (NES) are working really good and I'm confuse about it. But the your codes for Castlevania II: Simon's Quest (NES) still don't work correctly on my NES emulator FCEUX 2.1.1, even on Castlevania II: Simon's Quest (U) [!]. On what emulator you verify and see your codes to working fine?

I tested them with latest FCEUX and Castlevania II: Simon's Quest (U) [!] . First with the game genie decoder, then added the codes to the cheat list and then started a new game.
The invincibility code requires you get hit once.
The heart code only works at night, when foes drop a 1/2 heart.
The buy all weapons code works perfectly, in the first town, when you buy a holy water, it will give you all the weapons.

Thank you, @Whipon, I verify your codes in absolutely the same way.

However, in the database there's no notes for that. You can add descriptions for your codes?

Also you can verify the GameGenie codes in my posts #11 and #12 and you fix them if this is possible because I tested them only with ROMs with [!] and the problems that I described for them still appears?

Except the invincibility code, the other two are self explanatory.
However I'll add some notes to them, to avoid further confusions.

I noticed something, you may not be aware of.
You're adding the codes to the cheatlist from the Game Genie Decoder/Encoder.
You can do that with some codes (codes with only one possible affected rom address). But certain codes affects more than one address. So by doing that, you may find some bugs.
That's because the FCEUX cheat engine doesn't use the compare value. It justs patch the code at the given location.
Take this in mind when testing GG codes. I suggest you to use NEStopia or VirtuaNES. FCEUX doesn't seem to have any way to use GG codes with a compare value.

Added your code nolberto, didn't know what to do with the rest.
