Changing kickstart rom disk insert image & other stuff

[Gulliver]

Hi, i hope someone can help me over here, probably someone with a deep knowledge of AmigaOS.

The story goes like this: I have already, with the help of Remus and Romsplit, built my own Amiga 1200 kickstart rom which involves basically kickstart 3.1 v40.68 (A1200) with AmigaOS 3.9 Boing Bag #2 rom update plus some other stuff. It works like a charm but then, as it is a custom kickstart rom, i decided to change some version string and copyright messages with an hex editor. No problem, but i then came to a point where my humble knowledge fails and i truly require help!

So this is what i would need to know:

1-Which hex values do i have to change in exec.library v45.057 so that i can change in the kickstart rom disk insert animation screen the colors of fonts and background

2-Can the floppy insert animation be changed to something else, custom made (That would be so cool!)

3- Can the Amiga tick logo be changed? How?

4- Could the entire screen be modded? How?

I hope there are still talented hackers who would enjoy this challenge!

PS: Dream mode: It would be great if instructions for these mods are provided for the different 3.1 kickstart rom versions out there, and the 3.5 & 3.9 updates!

I am sorry i meant exec 45.20 (45.057 is the kick version when rom is updated with boing bag 2). They dont need to dissassemble the entire exec, just trace the code to where it draws that disk insert screen and then create a patch to change the visuals!

Hopefully someone may be able to do it!

Wow, thanks, i knew it somehow could be made, i thought it was in exec.library itself. Please try to find out where your strap module is, of course if you even supply the source code and the binary file, it would be great!
