The save data after the second reset

Because check sum does not accord, after reset, the save data erasure begins. By resetting in such a way that there is left only "K-" (4B 25) of the data, check sum agrees according to expectations.

Checksums

This game has two kinds of the checksum. It is EX-OR of 16bit and summation of 8bit.
  • 0x4B + 0x25 = 0x0070
  • 0x4B00 XOR 0x0025 = 0x4B25

Character code

To attach it excellent before; the character of being usable is 0x20 and 0x25 and 0x26 and 0x30 - 0xFF. The character who is smaller than 0x20 is used for an instruction code. Specifically, please look at here. http://datacrystal.romhacking.net/wiki/Mother_2:TBL In the case of EarthBound, it becomes a bigger number. http://datacrystal.romhacking.net/wiki/EarthBound:TBL

The save data that all became zero

The element in which a game judges whether it is data under adventure is existence of the character of K of "PK favorite thing." It is reopened by the top left corner of Tenda Village. Besides, it becomes the game over promptly because a party member is 0 people. However, there is slightly room to open a menu only as for 1 frame. Furthermore, this place can cause a text glitch. And text wait becomes 0 incidentally.

Text glitch

When a text glitch was caused, it does not lead to the point when a random number is not good. Therefore I move two times of cursors even more. When a value of text pointer $7E9979 of MOTHER2 approached $000074, I operate 1P and 2P at the same time. I push "1P=YSv<0,2P=BY^XLR03" at the same time to carry out "08 56 79 C8 00" instruction code. 0123 buttons were used before in Glitch TAS of Super Mario World, but they did not have a reaction in Snes9x. Therefore I was able to arrive to the last screen without using a debugging menu unlike the last time.

Special Thanks

Mister. He corrected the sentence.

Just when I thought this one couldn't be broken further... This was like the 'Dance, Dance, Revolution!' of Earthbound TASing! Definitely keep the extra input feature intact with the encode (if possible) if published. Otherwise, staring at just the start-up screen diminishes the entertainment value. All in all, an eye-catching run! このTASはとてもいいとおもしろいですよ。 ピロヒコさんどうもありがとう。

I can't really vote yes or no on this until the explanation gets added. Otherwise, it just looks like almost 3 minutes of goofing around for no reason.

Interesting watch, I enjoyed the musical section at the beginning to pass the time, but that kind of is everything the run has going for it, as there literally is no gameplay to it. I guess it's a vault here.

Given that it has to wait for the correct frame counter, I'm not sure there's a more entertaining way to pass the time. Voting yes on this.

Given that there are more than four buttons used here, I'd be more inclined to say this run is like Pump It Up or Pop 'n Music instead of DDR ;-) But then again, only three buttons are used most of the time. I admit I liked hearing the really fast uses of the up arrow that sound sort of like drums. However, the glitching and corruption don't themselves look interesting to the viewer. The input display is great, but it's not enough to make this get a good vote from me. It also doesn't help that very little of the credits is seen either. I have to vote No on entertainment, but this is a spectacular technical run.
Used to be a frequent submissions commenter. My new computer has had some issues running emulators, so I've been here more sporadically. Still haven't gotten around to actually TASing yet... I was going to improve Kid Dracula for GB. It seems I was beaten to it, though, with a recent awesome run by Hetfield90 and StarvinStruthers. (http://tasvideos.org/2928M.html.) Thanks to goofydylan8 for running Gargoyle's Quest 2 because I mentioned the game! (http://tasvideos.org/2001M.html) Thanks to feos and MESHUGGAH for taking up runs of Duck Tales 2 because of my old signature! Thanks also to Samsara for finishing a Treasure Master run. From the submission comments:
Shoutouts and thanks to mklip2001 for arguably being the nicest and most supportive person on the forums.

I will miss the Spankety Spankety letter to Red Swirl Battle to "The End?" but the technical side is good stuff. Entertainment is not.

I am so glad the other run that pirohiko did is in another category, since this completely destroys whatever "story" said run had. 0_o Edit: Nice menu music at the beginning. It was enjoyable even without the DDR GUI (which I noticed was covered by another tab I had on. >.>)

Well, the encoder would likely need whatever script used to generate that input display. I can't even view nicovideo, so I don't know what it is like...

Is there a technical explanation of why the check glitch (checking the edge of the map) permits executing input as code? Does the way in which the check glitch was used in this game provide the same or different possibilities as in the previous glitched TAS (that does check glitch in onett)? If not, why not?

Lol the official encode definitely needs to have the DDR type side panel just because it's so much more interesting that way :)

No. Just no. That's not part of the game at all. Btw, if the video's only entertaining not because of the gameplay, but because of the edits done to it, then it shouldn't be legible for the moon category. In fact, I wonder how many votes were "Yes" solely due to the DDR GUI in the submission encode. :P

Personally, I didn't care much about the DDR display. I think the real charm of the menu playaround is the music beats produced by the inputs, instead of the external display. I don't know what the other voters may think, though. I guess/predict that the movie ratings will hold up well enough to retain a Moon. Can't yet tell for sure, though.

This product contains glitches known to the state of California to cause egg defects. <Masterjun> I'm just a guy arranging bits in a sequence which could potentially amuse other people looking at these bits <adelikat> In Oregon Trail, I sacrificed my own family to save time. In Star trek, I killed helpless comrades in escape pods to save time. Here, I kill my allies to save time. I think I need help.

Not me. I voted yes because I'm a fan of runs where a game suddenly jumps into the endgame sequence for no discernible reason.

Impressive run! I only wish I could fully understand all the planning and implications that went into this run (because I'm no good at disassembly, coding etc. yet). Specifically, I don't understand this part at the second reset:
By resetting in such a way that there is left only "K-" (4B 25) of the data, check sum agrees according to expectations.
So as far as I understand, some way or another (I don't understand how), you made the savegame so that you start out in the top left corner of the map with 0 characters and you get to do something for only 1 frame before the game would gameover (because of 0 characters). In that frame you active the text glitch which - to my understanding - works because you "check area" at the 'out of bounds' part, like in Onett or in the tent in Threed previously. So my question is only, why exactly do you get to start out in the top left corner in Tenda Village?

I do the first reset just before "P" is written in. The game does the error check of save data very first afterwards. Because check sum does not match then, the data are removed from the lower part. And the second reset is to do it when only "K-" is left, and check sum is correct, and it is said that it is right data. If a letter of K of the PK exists, it is judged that it is used data. And it is reopened by the corner of a big map because the coordinate information becomes 0.

Should we mention that Opus audio is being used and make some sort of effort to inform people they should, and where to, obtain the audio codec? Or do we hope they figure out how to find out what Audio stream the video is using and then google it? Ok, All I could find is some source code and dome EXEs for manually encoding or decoding opus files. I guess I'll have to stick to Youtube or the Compatability video files. Ok, I checked for an update to MPC-BE and it has it. Edit: That was horrible, but it least it was short and the Music was nice.
