Good point - I only generally use it for a quick 1.3 session and then can't wait to get back to normality! Too much orange and blue is bad for the sanity!
And on one weird A1200 I own, I have to switch off for what seems ages to remove 1.3 via Relokick, otherwise up pops the hand again when I switch back on!
But... back to the question... I don't think TUDE can be made to make KS1.3 reset-proof. But then again, it only takes a few seconds to load and boot into 1.3.
