Line 88:
#Activate the glitch in [[bp:Kanto Route 1|Route 1]] and enter Pallet Town (the music and palette will change).
#Enter Professor Oak's lab.
#F335 (Echo RAM for D335) will change to FF. Walk 548-551 steps (137×4) and land the last step through the right exit mat warp. Ignore any '(x)は ちからつきた' (fainted Pokémon) messages on the way.
Line 95 ⟶ 96:
==Eevee Trick==
The Eevee Trick, discovered by [[user:Pawny|Pawny]] (among non-Japanese native people{{clarify}}) allows you to 'patch' the effects of the Hall of Fame on your save file. It also allows you to get up to 25 Eevee. After you watch the credits after warping to the Hall of Fame and reload your save file, you will be outside of your house with the dokokashira door glitch's warping effect still active.
Travel the same amount of steps required to warp to Route 7, then travel to the right-most back entrance of the Celadon Mansion and enter it (the amount of steps required to enter the mansion don't really matter). Do not enter the left-most entrance or you'll warp to somewhere else.
Line 116 ⟶ 117:
In order to alter the wrong warps every four steps, three criteria are necessary.
*The 199th Pokémon must be poisoned (F337 (Echo RAM for D337) must have bit 0x3 set; as it does for the 0x0C value loaded into D337 upon entering Pallet Town). Note that even though this Pokémon is in fact poisoned, the poison screen transition/sound effect may not occur. D337 is the x-coordinate of the Professor Oak's laboratory door warp.
*F334/F335 (D334/F335) (the 199th Pokémon's current HP; 0 to 65535) must first be a 16-bit value greater than 0 (otherwise the wrong warp is always Pallet Town because poison does not underflow a fainted Pokémon's HP)
**Additionally, if it is possible to adjust F334 to a value over 0 (so F334-F335 represents 256*n as the HP where n>0, it is possible to access relatively high warp IDs as in this case, F335 will wrap around from 0x00 (Pallet Town) to 0xFF ([[AreaDexJP/RG:255|glitch map 255]]) and below whenever F334 is decremented (a loss of 256 HP). From 0xFF it will take 255*4 steps to become 0x00, after which taking another four steps decrements F334 by 1 and sets F335 to 0xFF. This process of having to walk 256*4 steps to underflow from 0x00 from 0xFF repeats, until F334 becomes 0x00 as well - from there on the wrong warp is always Pallet Town as above.
*There must be no 0xFF before D1EA and after D124.
