Because mine is patched already with polygamy. Are you using by any chance an XOR-function to switch the byte (aka swap the byte between "patched"/"not-patched")? Because if the byte was already patched and you use such method, then you actually are unpatching the file...
PS: also, there are more possible values to patch to get Polygamy (some better then others)

I suggest to change 0xB7 to 0xB6 on memory location 0x004DFFE1, nothing else (blah, I didn't say that
).
