Dead rising OTR xbox360 help unlocking debug menu

I see on another site stipo said to poke a byte for enable_debug_jump to 01000000. I used ida pro to find its sub_ and i changes all 7D8802A6 to 01000000 but it does not show . Anyone done this before, am i doing something wrong ?
Any help would be great..

is it the review build? It should have debug unlocked by default if it is. OTR Review CL:530046 Should have everything by default. The only thing i poked was the CL: Text, as it doesn't authenticate normally.

Now If it's retail, you have to poke it before the game actually fully launches, you can't poke the value while sitting in the main menu. Which logically means you should brute force that poke into the xex. Edit the new instruction with a HEX editor and it will always launch with debug_Jump, no pokes needed.

 

What i did was change the xex with HXD. Then put it back in the retail game ,but nothing happened (no debug jump).
