537. You ask for the Rick Astley special limited edition

yeah, along with the 82, 83, and 81, AFAIK. They'll all crash eventually.
The reason why is because of how emu8x uses extra RAM.
Page $82 contains ram page 1 of the emulated calc, and page $83 contains ram page 0. At the beginning of page $84 is where the emulated LCD is backed up. Other stuff is stored in appBackupScreen. (L3 for you Axe programmers )
On the calcs w/o the extra RAM, all the extra pages are the same. Pages $82, $83, and $84 are all the same page.
This means that, for the emulated calc, a write to, say, $9D95 (which is on ram page 1), will be mirrored at $DD95 on ram page 0.
When you press left-right-alpha to bring up the emulator menu, the emulated LCD is backed up, and overwrites $8000-$82FF and $C000-$C2FF in the emulated calc's RAM.
Keeping it from crashing is an art
Edit: Actually, the LCD backup might be used actively, which means those addresses mirror the LCD constantly.
And for the 86, it's even worse, because it uses all the extra RAM pages.

I'm not sure there's a large enough portable one around the house...

Back!
Having finally worked my way through the posts I missed to this one, I'd just like to say that I have returned.
And, slightly off-topic, school where I am starts in exactly two weeks

Nice

A lot of you seem to have multiple calcs O_O.
I only have one TI-84+SE, purchased for school from Walmart. (For under $100, IIRC, after several coupons (not me, I wasn't the purchaser ))

Yeah, the time is absolutely awful for me (eastern coast here). However, I guess I could always check the logs if making it earlier is too difficult.

Nice DJ!
