Hello, I've read this topic i think it's very interesting, specially information about 480p->720p patching.
First of all, thanks to Raidn for all this information.
Here is my question/trouble:
I've Chessmaster game, patched it succesfully, so it's working now in progressive mode (480p).
I think that a chess game doesn't need a lot of resources for working properly, so I've tried to patch it to run at 720p with no success.
Here are the changes that i've made:
Original (IDA-view-A) ->
seg000:00033D79 mov ds:dword_2AF8D8, 280h
seg000:00033D83 mov ds:dword_2AF8DC, 1E0h
Patched->
seg000:00033D79 mov ds:dword_2AF8D8, 500h
seg000:00033D83 mov ds:dword_2AF8DC, 2D0h
So, that's it in hex view:
00 C7 05 D8 F8 2A 00 80 02 00 00 C7 05 DC F8 2A 00 E0 01 00 00 A3 E8 F8
->
00 C7 05 D8 F8 2A 00 00 05 00 00 C7 05 DC F8 2A 00 D0 02 00 00 A3 E8 F8
With this changes I get a black screen and the game doesn't initialize freezing the xbox .
Any help will be apreciate!
