Thepenguin77, I tested t32.8xp on a Ti-83+ Silver Edition, and it works.

However, I started implementing the ports in Crabcake, and I think I'm doing something wrong because the RAM doesn't unlock.

Here's my code:

Code: [Select]
Is15MhzCalculator:

;Thanks to thepenguin77 for finding out this new method for unlocking RAM.

call FlashUnlockExploit
in a, ($25)
ld (StateOfRam), a
in a, ($26)
ld (StateOfRam + 1), a ;In case the user wants RAM permanently unlocked,
;or in case permanent unlocking causes crashes,
;the old values for these two ports are saved


xor a
out ($25), a
ld a, $FF
out ($26), a

B_CALL $4F3C

I'm sure that somewhere in TI's vast vaults is documentation on what ports 0E, 0F, 15, 24, and 2D do. But they'll never tell us without a court order, and they they'd fight it for no good reason.

Hot_Dog, the only reason that wouldn't work is because flash isn't actually unlocked. So check port (02), port (25h), and port (26h) and make sure that everything looks correct.


DrDnar, don't forget about ports 0Bh and 0Ch.

Oh yeah, I forgot that I shortened BrandonW's routine for using on simply the Ti-83+ BE.  Hence it wasn't "universal" ;D
