The wide bug is that the umpire calls a decent line ball outside the off stump a wide when the CPU bowls. It must be possible to fix it, definitely a job for hex editing.
Meanwhile I tried to tweak the CPU to bowl less yorkers but when I do that it bowls one too many four balls in Test cricket. In ODIs the umpire calls those wides, so still some work to be done on it.
Anyways I am attaching some of the files that I have used so far. Please bear in mind this is about 1/2 to 1 hour spent on tweaking so it is defintiely not a finished product in any sense. If there are some things that you notice in this patch that may need fixing then feel free to ask.
Although there are quite a few config files in one big files all of the config files are also on their own. I am not sure which one is used in the game though. I guess the cfg ones might have been used but import all of these files anyway.
Firstly download BigGUI software that is available on this forums. Then run BigGUI.exe, go to Cricket 2005 folder, then go to data folder and open data_pc.gob file. Then go to edit menu and import the following files. After you import the files you will not need to compress the cfg files but only need compressing the 2bb7ad25c9aa96dc7b6f670d84a4df83.big file. To compress after you import the files in the zip file here, look for 2bb7ad25c9aa96dc7b6f670d84a4df83.big file in the BigGui list of files and click on the 2bb7ad25c9aa96dc7b6f670d84a4df83.big file. Then go to edit menu and hit compress. Quit BigGui, play Cricket 2005 and you should see the difference.
I have done a very quick job on the 50 overs odi CPU pacing file but if need be you could use any of my or the AI patches Cricket 2004 50 Overs pacing files. I haven't played a full 50 overs so can't comment how good the pacing is but feel free to let me know what you guys feel.
You will notice batting may have gotten a bit easier. These tweaks are only for hard level and do not work on medium or easy level.
BTW it is most important to backup your data_pc.gob file before you attempt to import these files.
