Mixed opinion. It's good, but outdated (refers to a much earlier state of the disassembly, it has improved a lot since then. Not sure the constants it's referring to haven't changed names since; if that's the case, I'm for removal unless it gets updated)
Delet
Not sure either. The format isn't great, and a lot of the info is now covered by Pan Docs. Plus there are typographical and grammatical errors (plus a .txt file that was clearly intended to be read with a certain viewport size) that hinder comprehension.
Agree to move, but it's superseded by gbz80(7) anyways.
Keep & move.
Some parts are severely outdated, other parts are still good and relevant. Against keeping it as-is, but it'd be a good idea to make a copy with some sections (such as those about official devkits) elided.
Superseded by gb-bootroms. Relevant both to emulator devs and as historical info, so I think it fits a misc section.
Outdated.
Same. Might be worth porting to Pan Docs with attribution if it's incomplete in the current docs.
Good as a general resource to emulator devs and all programmers. Create a "technical references" section maybe?
