Yes that's true. I guess once the ROM image works in UAE, then we can think about getting it burned to a chip.
Sure you can burn as many 1MB chips as you like, but there is nothing to plug them into.
I am aware of some utilities that read the data from the ROM chip and save it to a file. Would this save the 3.9 patched ROM information that is loaded in RAM, or would it rip the 3.1 kickstart directly from the ROM chip?
Well, since ROM cannot be written to, you just get the original KS 3.1 ROM contents.
Running romupdates can't be dumped to a file, anyway. Or actually you can dump them, but they would then ONLY work in this particular absolute RAM address, and nowhere else.
