Mhmm, this seems like this trick might be best avoided if it gives different result on various calcs x.x

EDIT: http://ourl.ca/4129/102147 safer way to do it, I think (although IDK if it's the most efficient one, in  terms of speed and optimizing)

The only cool thing about it is that you don't do anything else, the driver does it automatically.
Btw, can anyone else replicate this? I can post a vid later, to demonstrate this.

No flips occur on a S-0702A 83+SE and a S-0106F 84+SE, when outputting $0C through $0F to port $10. Maybe a small effect on contrast, as TC01 described.

So I have a special driver... woohoo...
I'll get some pics so you can see it for yourselves.
Edit: got the pics, they're attached. They're named to correspond to the port output that produced them.

WOW!  I can't believe that actually works.  Imagine playing Mario like that.  Do the asm programs work?

Since absolutely nothing touches the setting (except a RAM clear), everything is like that until I put it back by outputting $0C to the lcd. I'll get you another picture of, say, Tetris Marathon. Hold on. :P
Edit: Here you go. :P Plus a bonus! (I'll stop probably stop posting pics now)

Doesn't work on my TI-84+SE S-0408D, nice though, if only they implemented it in more models :(

Yeah, currently I'm wondering what LCD driver I have... Maybe I should open it up...

Seems like this is a pretty rare occurrence o.O Too bad, it could have been exploited to be sooo annoying ;)

Looks cool, but when I tried it, nothing happened. Oddly enough, my serial number ends with P-0908M, which should mean I also have an M revision from P factory, right? Perhaps, mine just has a worse LCD driver...


Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

This is confusing... I feel special. :P
If the LCD drivers are clearly labeled, do you think I should open it up?

Might be a good idea. Make sure not to damage anything in the process though.

Doesn't work on mine, plus bad screen.

And while I had it open, I made the LCD really clean.
