Issues using cheat with American Metroid Other M game, after Sector 3 (magma one)

[Duncan Idaho]

Seems this game has a huge issue any codes suddenly after entering sector 3 all codes stop working, all of them, from invincibility to inf ammo, they break, i am not sure why it happens all i know it happens just after a small sectionw here samus is exposed to heat, if using the codes she will start taking damage, and from then and onwards the codes are forever broken for that save file

i have chekc the ID, it matchs R3OE01.

unless i somehow got a fake signed game, where it's patched to have an american ID.
