Did you rename Generals.csf.mod to Generals.csf and move it to the English folder? If it didn't say .mod then you have to turn off "hide known file extensions" and then rename it.
Did you delete the extra INIZH.big from your data/ini folder?
what language is your ZH version?
My game is in English.
Thanks for your help, i placed the .csf file in the English folder and now I get the missing tooltips back.
