While surfing around (coincidentally, with my Casio by my side), I stumbled upon this Easter Egg:
*link at the end. Read the entire post before clicking. YOU HAVE BEEN WARNED.*
It basically tells you how to enter the Debug screen. Yet, there is a catch. I was o so well, so well, trying the many functions, and one of them was named RAM. I didn't find anything special there, because previously I visited ROM, which just made a test for the ROM. After the RAM test was done, it showed a message: "Main memories cleared!"
At first I just thought, "Well, everything is going to fast, I am looking at the screen fast and such, probably I haven't read it correctly. Probably it just cleared the ROM or something..."
And then, the classic "Welcome" screen.
At this time, my pulse was:
{
...../\.......... /\.......................................................
----/...\.../---/....\..../----------------------------------
..........\/...........\/..................................................
}
Very, VERY luckily, I had a few backups, but they were very old, unfortunately.
I'm telling you, I had about 30 programs, NOT kidding.

Tomorrow, I've got a looot of work to do...
Ok, you have been warned. This Debug screen has some interesting and some normal stuff. Yet, the RAM option is this dangerous. If you want to know how to do it, go to the link at the end. But let me warn you first:
I'm not sure of how do you get out of that screen. Somewhere in the comments on that page says some weird stuff.

If there already is a topic about this, then sorry.
If the moderators think that this shouldn't be here, than do what you need. (Sorry, also)

Thought so. But there isn't any topic about it, is there?
If not, well, then this is the first topic. Simple.

Hehehehe... I remember this for my CFX.

Too bad it doesn't work the same way on the fx-9860G.

Reading this comment in that website :

This does work on the FX-7400G, but I did it differently. What i did was I opened the battery door, flip the switch in there so it will come on, turn the calc on. Now remove the little black sticker in the top left of the battery door. At the top of whats exposed, there will be two little test points there at the top side by side. Short those two together, and it will go into a test mode.

I realized something :
When you open the 9860 batteries compartment, you can notice a hole not far from the reset button. In this hole, you can see two contacts.
Wouldn't it be a test mode too ?
Anybody tried to short them ? I'M NOT TELLING YOU TO DO IT, just asking if anybody did it already.

I did now , with a 1k resistor.
It starts "Gy363 OS update", probably as quick way to reflash the calculator when it is being serviced.

What better place to post the following than my own topic on the subject?:

Yesterday, I left my calc uncovered, for easy access. It was inside my school backpack, because every once in a while I remember some stuff and I put it on a "memo" program on the calc itself. When I reached home, I pulled it out to write another thing down, and wouldn't you know it: it was on the main debug mode menu! I just couldn't help but to swear I DID remember there was a way to exit it, but on the bottom of the main debug menu there were 3 random numbers I never saw before. So I though I was in some sort of alternate selection mode... I pressed several buttons, including 9, which lead me to the screen lighting test. Pretty as it may be, I couldn't exit it (apparently, AC/ON was being a b***h and only let me press it at the 2nd time I tried). Well, luckily I managed to quit it undamaged. But the real brain teaser was the fact that it was the first time in... Ever I left it uncovered, for some hours, and in the chances of ([50 keys]^[3 key combination]-[2^3 repeated keys that need to be cut of from the equation]) 124'992 to one.
I just wanted to smack the calculator WAY hard against the wall. Alas, I couldn't just do that.

And to anyone interested, to exit the menu without damage, press 0 on the main menu, and choose NO.
