if its the design part that scares you most.. Yener90 wrote a designer program for the graphics part of his CI/CIU called
CIDesigner0.4a.7z in topic below:
http://fileforums.com/showthread.php?t=93196
there is a detailed how-to in that topic as well. also look thru the "sticky' topics at top of this forum for his CIU Source file & info on what needs to be where, its a
huge
thread so lots to go thru. Ive posted enough information to make your head explode... LOL sure seems like info overload.. but its not too bad.
download his source file open & extract the setup.cab so you can see what files are what & where they need to go. then browse thru the ISS script & setup.ini to see how its put together...
Im still learning on the design part myself & its lots of trial & error to get things just right... doesnt happen all overnight, can takes ages to get it right... if you need specific help just look at the conversions posted who wrote them, & Private Message them rather then asking in a wrong topic.
