I think that's part of it, yes. And Star Fox never reached a state of completion. However, I'm not sure it was ever given its own subforum.

Don't forget thepenguin77; he did a lot of the testing and helped get most of the information in my post here: http://ourl.ca/11891/224537
I played the minor role of beta testing FLASHY (I took my 84+SE 1.02->1.03->1.02), as did a couple others, who can speak for themselves. (I think DJ was among them, IIRC.)

It's because the 83+ doesn't have the port that's been used to bypass the protection on the boot code.
We don't know whether or not modification of its boot code is possible yet, I think.

I did something else wrong, it works now. (I almost feel like I didn't press ON.)

Oh, okay. So TI's method of switching to mode 1 and then to mode 0, ultimately ending up in bank 1, is officially pointless

Calcdude, I figured out that you only have to execute code in a bank controlled by port (06).

Ah, okay. Do we still not know why just executing TI's code from bank 1 directly doesn't work?

Also, I figured out what was wrong with the LCD, I had a few "ld ($10), a" where I should have had "out ($10), a"

Oops

Excellent!
thepenguin has, as stated in the other topic (but I'll restate it here), created a modified boot code image that conditionally runs your own code before anything else happens, and Brandon's stated his intentions (he might have already done it) to make a similar version that either starts normally, runs what's on RAM page 0 (which is what thepenguin's does), or runs what's on $2C/$6C (which would be 84+(SE) only, I assume).

...everything new we learned about the calculator hardware on boot (which is weird)

Our current understanding, as I remember it, goes mostly as follows:
The calculator starts in a memory map mode that's mostly like mode 0 (port 6 controls bank 1, port 7 controls bank 2, port 5 controls bank 3) except that page $3F/$7F is swapped into bank 0 (where page $00 normally is). $00 is swapped into banks 1 and 2 and RAM page 0 into bank 3.
A jump ending in a bank swapped in because of port 6 (bank 1 in mode 0, additionally bank 2 in mode 1) swaps $00 back into bank 0.
Ports $0E and $0F have nothing to do with this; as far as we know they are worthless.
Last I checked thepenguin still has not managed to successfully initialize the LCD himself.
The initial states of other ports can be found in the appropriate topic (state of the calculator at boot, to be linked shortly).
thepenguin/BrandonW: I probably forgot something/got something wrong, so correct me if I did.
Edit: Fixed information regarding swapping $00 back.
