Corrupts save data

When beginning a game for the first time, initial full data of 6 people are written to the SRAM. Only each existence flag and CRC value are renewed by 14 people who don't exist. In case of Bizhawk and Lsnes, their CRC value will be 0x4EE4. The error detection and correction is made an SRAM of this game using CRC-16-CCITT (Initial Value is 0xFFFF). I generated the arbitrary CRC value by adjusting several parameters of the new character to pass that fastest. The person who has 255 items is generated by precise sub-frame reset when saving data.

Comments

  • I reset to cut a company's name logo.
  • CRC value makes the new character which becomes 0x4EE4 at the training grounds.
    • The name was the fastest 1 character "あ(0x91)" and be "blank(0x20)" 7 characters.
    • Neutral(+0x01)-Thief(+0x0C)-Gnome(+0x60) was made to adjust a parameter to 0x6D.
    • Strength is 0x08, I.Q. is 0x0A, Piety is 0x0B, those were chosen for the CRC value adjustment.
    • A lowest value of a bonus point is 7, so the rest points were given to Vitality and Agility necessary to the Thief.
    • After sub-frame reset was done, his CRC value agreed with 0x4EE4.
  • His order was changed at the training grounds, and the next person was re-named a diamond(0x83).
  • When he returns from the maze, he has the "Heart of ABRIEL(0x83)" as the 54th item, so he reaches credit.
Fog: Judging.
Fog: Another well executed run from pirohiko!
However, with the run now essentially devoid of all gameplay along with the relatively mediocre audience response, I will be downgrading this run to Vault.
Accepting to Vault as an improvement to the previous game end glitch publication.
feos: Let's pub some tiny ones while Sabre Wulf is being sorted out.

Previous run will have to be added to http://tasvideos.org/Movies/ObsoletelyFabulous.html if this is accepted. Subframe resets are too strong! Yes vote although I think entertainment value is lower now

Well, I think we could have a separate branch, considering this is memory corruption/SRAM glitch, whereas the previous run is not.

Oh yeah, you're right. (For example, [2687] GB Pokémon: Red Version "save glitch" by MrWint in 01:09.95 and [2680] GB Pokémon: Red Version "Brock through walls" by MrWint in 22:02.94 are different branches.)

Wait, so this is going to obsolete the previous run? I thought this would be SRAM corruption while the other would be any% (or game end glitch)?

It is, because it does not make sense to have two branches of games being completed in a minute or less, which shows off none of the game play.

I guess that would be the same precedent as [2466] SNES EarthBound "save glitch" by pirohiko in 04:04.35 obsoleting [1946] SNES EarthBound "check glitch" by pirohiko & MUGG in 09:01.77, then. Previous request to add old run to Obsoletely Fabulous is re-instated, then.

There's a topic for that sort of thing, where these sorts of requests aren't as easily overlooked.
