Ok, then I'll try to do that!
I'll put together some readme file now...

So, here's the enhanced Fake Reset program with a keyhook that I talked about.
It's absolutely impossible to tell the difference between a faked and real mem reset screen Rolling Eyes

Improvements

Triggers when you enter the RAM or mem screen using the [2nd][mem] menu
Now displays the true basecode version number
Sets the TI-OS default contrast value (1Fh) when displaying reset screen

And especially for you Anduril66, a program with the same features as the one I posted but only with a mem reset screen without keyhook.

For whoever asked about menucurrent.

ld a,(menucurrent)

will return a value for what menu you are in to A.

Each menu will return a different number.

If I remember right (you know without looking it up)

menucurrent+1 is the upper menu

So, if you are in the programs menu

menucurrent+1 will return a different value depending if you are on Exec, Edit, or New.

Finally, menucurrent+2 will return the program your cursor is over. I do not remember if it starts with 0 or 1, but as you press down, the number will increase.

That's exactly how it works. All values start with zero, FYI.

Here is a modified example: to make it even more perfect... Razz

Edit: now the runindicator works too!

Has anyone ever made a real one?

Jup, was my first ever written-in-hex-codes-manually program I ever made but it was supposed to clear the screen and it was on my friends calc and he didn't like it. =(

Yes, I typed in random hex.

Hi folks,
I did a little modding to the Fake Reset 2.0 in response to the "Help! Noob Here" thread and I thought I'd post it here as well.

changes:
- I added the code by JeePee
- it now autodetects calc type (83+/83+SE)
- messages are displayed accordingly
- it sets the exact TI-OS default contrast - also according to calc type
- positioning of messages is now 100% identical to the TI-OS reset
- font now also 100% identical to the TI-OS reset

Get it here:

Can't you just call the TI-OS code after the reset part?

you probably could with some of it, didn't do it though. But perhaps in Fake Reset 4.0 - it might make the code a little smaller.

A little? All you'd need is a JP <address>.

wrigley · Advanced Member Joined: 19 May 2004 Posts: 399

yes, you could only save a little bytewise. Percentagewise you could save a lot, as you say - probably around 30%.

besides my mod only changed it from being 473b to 635b, not from 473b to 1,5K

EDIT: btw do you know which adress to jump to? If so, then please do let me know, then i'll implement it right away.

Arcane Wizard · Posted: 17 Jun 2004 04:46:38 pm Post subject:

Wouldn't a simple program with a jump be less than 20bytes? Sounds like quite an improvement from over 473b.

As for the address, you might want to contact Iambian Zenith, who has deassembled the TIOS, he should have some notes on it, or maybe not.

Thanks for the reference to Iambian Zenith, I think I will contact him.

as for the jump/space thing 473b is for installing/uninstalling the hook, displaying "installed" message, the hook itself, the OS-check, changing contrast, and displaying the it's-been-reset-screen.

in the 635b version additionally there is the "Resetting All..." message, the calc check, the displaying of SE version of the it's-been-reset-screen and the SE contrast settings.

Providing that the <jp address> is the same as on both calculators you would still need the installing/uninstalling of the hook, the displaying of the "installed" message, the hook itself and the displaying of the "Resetting All..." message.

Ah, yes, you would still have to do the stuff the TIOS does before actually clearing your ram.

If I recall correctly (i.e. I'm not delusional again Razz

) there's a way to get the version of the TI-OS, if you're really clever the version wouldn't be hard-coded, i.e. it'd display whatever version the calc is. Smile

It already does :P

Try it out, just make sure you don't have the Omnicalc functions installed when doing it, because they will stop it from working.
