If you are using a text editor that allows regexp for your find/replace then you can just do something like the following
find:
^(.+=.*)a(.*)$
replace with:
$14$2
I know this woul work in EditPad Pro (it's what I use) and you just need to do it for each. Apart from that I can help you write a JScript file to just go through and do everything for you and put it into h4x0r.ini
