Other Calculators / Make PTT not Delete Groups
« on: July 17, 2011, 06:14:05 pm »


Here's what I did. Go to the reset ram menu, (2nd, +, 7, 1) and press 2, let go of 2, and hold clear really fast. If you did it right, your archive will appear to be empty. Then, just do the classic left + right + ON, and enable press to test. Everything will look normal. But after a quick ram clear, your archive is back including your groups.

This same trick can be used to:
  • Protect your programs from 5+8+ON
  • Protect your programs from 2+8+ON (Singapore)
  • Protect your programs from the entire Reset Ram>Archive menu, (2nd, +, 7, right)



I know I've already made OS patches to beat it, but the key here is that this doesn't require OS patches. So at least now, if you ever get stuck in a weird situation, you can get by without deleting your groups. If you're lucky, you might even be able to trick your teacher with the Clear Arc vars too.

Great game, you got my vote. And a +2 (because I haven't been watching this topic at all)

I also agree that you should do some key remapping :P

Well, I played them all, and I have to say my favorite is Tag. Very similar to portal, just slightly different.

This game is quite challenging, some of the levels took me 15 minutes to figure out, and this is a calculator game. In fact, I'm only at level 17 right now and I'm going to save it for later. But I think one of the keys is that it is actually a puzzle, because if I played through it again, it wouldn't take me nearly as long. This shows that it's the puzzle causing me problems and not the game.

And, this is just a personal preference, but one of the things I really like about it is that it is in one program. :D  (Don't hate me)

That will stick as long as something else doesn't kill it.

I thought the Mem-clear do that...

Well, the my first version of NyanMem moved the swap sector, this involved modding the OS to look somewhere else. (Because people on IRC said you had to have one ;))

However, that is not the case, my newer version just deletes the swap sector so you can use it as variable storage. It will come back as soon as you do something flash related though.

What happened to you was that you ran the first one which modded your OS. Then you left it that way and ran the second one. The reason you can't receive apps is because your OS is still looking for the swap sector in a place that it's not. So run the original NyanMem again, uninstall it, and you'll be good as new.

No, this is as small as I can make it without leaving part of it out.

And it's not really dangerous, your calc is empty anyways. It's not like you're going to lose all of your files.

This game has left me speechless. Words cannot describe what I am saying. I have only been able to beat this game by cheating severely, I know it's not in good taste, but I don't care, this game is indescribable.

For those who want to see my valiant attempt at this game, witness my .gif. But remember, I cheated, and unless you want to be a cheater, I suggest you beat the game before watching this. Watching this before you beat the game will most likely lead to death.

Spoiler For Don't watch unless you've beaten this sick game:
You lied, beat the game first
Spoiler For Seriously, beat the game first:

What? Are you saying do 3>port ($05) then jump to $C000 essentially?

The answer is no, on hard resets, page 0 gets swapped into that bank. And before the OS/Boot code clears it, I believe they also swap page 0 in. So unless you pull out the little battery, page $83 will remain intact.

I know what happened, you didn't uninstall the old Nyan mem before you put the new one on. The old one changed the OS a little and that was what was causing all of your troubles. But since the new OS works, you're good to go.

Umm... Ok, here is what I did. Clear mem, run NyanMem, Clear Ram, send the app. That clear ram is actually pretty important for this to work.

If you can't send apps, just clear mem again. Sorry for this being so difficult :-\, you're basically tricking your calculator into doing something it shouldn't. However, I did manage to send an app that was bigger than NyanCat relative to my calculator.

Yeah, I forgot about some other stuff the OS does. But I think I have the solution, though, we won't know until my app finishes sending, which will be in half an hour.

For now, just run NyanMem again and uninstall it.

Edit:
   Here you go, I actually tested it this time ;D. Clear mem, run this, and send the app, I have no idea why it works, but it does.

Correct, neither of them fit normally on the BE. However, after you run NyanMem.8xp, the BE apps will just barely fit, which is what you want.

GreenFreak, you have to run NyanMem.8xp first, I included it with the apps. Then you'll have 557,056 bytes free and you'll be good to go.

Edit:
   Just make sure you're not on OS 2.55.

Nyan Cat Update !!!



I used my good camera this time, you can see the individual pixels. The setup here was no dithering and relative cutoffs.


I have made so many changes to this that I hope I can remember them all:
  • FS dithering now has a cap on the pixel brightnesses, before, pixels could go well above 255 and below 0 which led to leaching, now they can't
  • FS dithering now uses a serpentine pattern where it goes left and right on alternating lines, to help with ^
  • I added in a bunch of command line flags, which you will get to see when I release a copy later
  • There's an option whether to have audio/video loop independently/dependently
  • I added a perfect grayscale menu, just press ^ to get there
  • Contrast is adjustable via + and -
  • Contrast and refresh delay are saved to an appvar
  • Sample rate is now set at a constant 18,000Hz and the program calculates the cpu speed and adjusts accordingly
  • The runner is now bundled with the app



And for everyone who want to play NyanCat, here is the 84+ BE edition and the 83+/84+ SE edition. The SE version is 37 pages and the BE version is 33 pages because I left out the intro.

In each of the .zip's, I included every possible dithering style I can do. They are named based on their command prompt flags:
  • a - asolute cutoffs
  • b - both dithering styles
  • n - no dithering
  • o - ordered dithering

    The best way to decide which one you like is to send one to wabbitemu and run it. Then, just drag and drop the new file onto wabbitemu while it's playing, the new app will overwrite the old one and since they are the same size, wabbitemu will just keep on running.

    If you are using the BE ones though, you have a little bit of hacking to do. I included a readme and the file you'll need(use this), but the basic idea of what it does is that it moves your swap sector to page $30 so that you have just enough space to fit the app. The calculator isn't really stable like this, so after you're done with the app, just run the program again and put things back to normal. (I say unstable, but since the app takes up the entire archive, you'll never have problems) Also, don't run it on OS 2.55, you can, but it will delete a small portion of your OS (probably stat wizards).

    I'll have the converter out soon, I'm going to talk to buckeye later so I can figure out how to package it right.

How long would it take to buffer 15 seconds of vid to the archive, could you do it while it streams and just keep looping through what's there?

15 seconds would be 30 pages which is 7.5 sectors. A full sector erase/write takes about 2.5 seconds, but since it's paired with usb, probably 3 seconds. So that wouldn't be awful actually, probably only 23 seconds.
