Well, I got myself also now one of those 1 GHz Xbox consoles and can play now for example many emulators with a higher performance and still all my real Xbox game thanks to this great patch, so thank you very much Shonk for this useful tool
Now I only have one problem patching one emulator who seems to require patching and that is the latest BenderMameOX. When I ran it the first time with my 1 GHz Xbox all games were running too fast and so I patched the default.xbe what was possible with your tool. However after that the games in MAME ran still too fast. I think this is because the default.xbe works just as some kind of loader and the "real" XBE is the one called MAMEoX.xbe that is also found in the BernderMameOX folder (and I think most MAMEoX are built like that). However it seems that this MAMEoX.xbe can't be patched with your tool, it says the file was not patched when I try.
If you don't mind, could you have a look into that, if this MAME could also be patched for a 1 GHz Xbox? I think MAME is one of the emulators beside Surreal64 that really might profit from the 1 GHz CPU as many games didn't run very smooth on a 733 MHz Xbox. I am sure that some of them might be more enjoyable now with the 1 GHz Xbox.
Thanks again and greetings!
