The SP installation took about 2 hours on my machine. I brought my mum to a doctor's appointment and it had completed when I returned. I then performed an EDR which took quite a bit of time. I ended up with about 1800 defective items which I'm fixing now. I have about 1400 left.
Many of these errors are legit errors so far. Here's a list of stuff I've found and repaired so far:
Icon file or thumbnail missing:
This is sometimes a typo in the config.txt
References to a file called thumb.jpg instead of thumbnail.jpg
Incorrect power of 2
Missing thumbnail that's referenced. For missing thumbnails, I created an image called thumbnail.jpg in Gimp.
Typos and incorrect tags in config.txt file:
Incorrect tags such as mode 1 instead of mode timeofday for the smoke container
References to missing animation files, headcodes, etc.
When there are a bunch of the same errors by the same content creator, I will use my bulk handling tools such as File Boss to bulk copy a single thumbnail.jpg file to all of the assets after opening them for edit. With typos in the config.txt file, I use search and replace tools, and for the uniform color error, I've been using PEVs Images2TGA.
The process is not difficult, it's just time consuming. There still warnings I haven't bothered with, and I'll most likely face those with either the next service pack or version that comes out, but until that time comes, I'll live with that I've got.
