Dang.  Too bad, and good luck getting your motivation back!

I don't remember the boot code having a downgrade protection feature. Even if it did, it would have to be certificate-based. A certificate-based restriction could easily be undone by restoring your certificate from an older backup. What? You don't keep backups of your certificate? Shame.
Also, the TI-Boy issue can be solved by first copying the extra OS page to the 32 K sector, and then proceeding as normal. For that matter, you could patch the new OS to use that dang 32 K sector instead.
Do you mean $3C/$7C-$3D/$7D or $2A/$6A-$2B/$6B? IIRC the former already contains OS code, and with respect to the latter the .8xu format can't have the OS anywhere except the first and last sixteen pages.

You can't use it like "getKey(1) and X!=1" That will evaluate like "(getKey(1) and X)!=1", which is not what you want. To get the correct order of operations, you either need to put parentheses around (X!=1) or else change the order to "X!=1 and getKey(1)" Note: This goes for all of them, not just the part with getKey(1)

Also, before someone does it, no ':'s except as part of a string Sir, that can be optimized to Disp "The Game

Post your favorite useful (or useless) one-line snippets of TI-BASIC code here!  I'll start us off with a few of my favorites, list operations: "Returns how many times Ans is an element in L1
sum(Ans=L1"Finds where Ans is in L1 provided it only occurs once
1+dim(L1)-sum(cumSum(L1=Ans"Finds the index of the Xth occurrence of Ans in L1 (indexed from 1)
1+dim(L1)-sum(X<=cumSum(L1=Ans

Ah, okay. I might write one anyway for the practice

Ah, okay. Perhaps someone could write a program to strip a ROM of TI's boot code? I might be able to hack together a C utility to do this.

Sir, not necessarily. Wabbit is able to build a ROM based off of a 3rd-party boot page clone, not to mention that if KnightOS doesn't use any boot code routines, you don't even need the boot code; you can put a "jp $0000" at $4000 on page $1F/$3F/$7F.

Life's been getting in the way  I think I'll be able to start progressing again soon, I hope

Indeed, awesome video I've managed play Snake too, so it isn't a hoax. I wonder why you can't get it to work...

No, I meant that in the console, if you type SEARCH followed by a hex string, it will search for those bytes in ROM.

Ah. Calcsys does have a SEARCH command, though I guess you could briefly post the method you used like you said in the Contra thread?

Nice. I guess you didn't need to make those appvars after all

TASM supports nothing of the sort to my knowledge. To do relocation, you have to do something like this:
destination .equ $9001
.org $0000
.dw $CODE
;relocation
relocate .equ $
label:
dec a
jp nz,label+destination-relocate
In short, you need to define a couple equates and use +destination-relocate with any non-relative address (anything that's not jr or djnz)
