Hey mate,

great thing, if you will be able to gather all these softwares
it will be awesome. I am also searching for the gifextractor but no
hope. Till the moment i am tring to change the gif image in navboot
file using navtweak but i couldnt make it work. As i read Gifextractor
is great for having the option to declare image size. If u will get any help, please post. I will be searching and i will inform you.
