you have to download a program called i6comp to open and view the files in the data1.cab file using dos. data1.cab is protected using installshield6 a new version im an amatuer so dont ask too complicated questions.
when you download i6comp you have to open dos and depending on where you put i6comp type out a command line. e.g. if you put i6comp in your c:\ directory, type this. c:\i6comp.exe r -f (location)data1.cab gta3.exe (location) gta3.exe
this will replace the gta3.exe file, + location is the address on your comp where the files are located e.g. c:\windows\desktop\gta3\data1.cab
what i was trying to say before is that after you replace the file, and write a new cd with the updated files it wont install. it gets so far before telling you theres an error with the install. see thats why you have to change the data1.hdr file as well, unfortunitly i have figured out how to do that, but i will brief you as soon as i know. here is the i6comp file
i6comp
goodluck + if you get advice on how to change the data1.hdr file before me please let me know
