This will forever change the PC version of Final Fantasy VII, both for speedruns and casual playthroughs. The underlying wrong-warp, an extended Battle-Mode Warp (EBMW), was discovered by Neohart (http://www.twitch.tv/neohart).

Whereas Yuffie Warping (YW), discovered by Neohart in May 2013, and Battle Mode Warping (BMW), discovered by me in late 2013, both allow you to wrong-warp to locations of previous Game Overs, EBMW allows one to warp to locations associated with one's most recent escape.

In fact, EBMW works like this:
You die on the Mt. Nibel exit field on the glitched file (that file has the "No EXP/AP/Gil screens after battle" Battle Mode, which can be used for BMW), then load the file on which you wish to access the debug room. This has to be a savefile on the world map, otherwise the Battle Mode from the glitched file will be automatically updated when loading the file, in turn making it impossible to BMW in the first place. Afterwards, winning any world map battle will BMW you to the location of your previous Game Over, which is the exit screen of Mt. Nibel. As you enter that field via warping from the world map, the Battle Mode will not be updated. Therefore, upon leaving the Mt. Nibel exit field for the world map, you will keep the "No EXP/AP/Gil screens after battle" Battle Mode on the world map. Leaving for the world map and intentionally engaging in additional world map battles constitutes an extension of simple BMW, for now, if you win a battle, the game will no longer warp you to the location of your previous Game Over. Instead, it will warp you to the field whose fieldID is equal to the battleID of the battle you most recently escaped from (in FF7, every battle and every field have a unique ID). This means that if you win a battle immediately after leaving the Mt. Nibel screen, the game will crash as is there no field to warp to because you have not escaped from a battle yet. If you are familiar with how FF7's battles (aka "scenes" aka "formations") and fields are stored within the game code, you know that almost all world map battles have battleIDs of less than 288 (some special world map battles like the Midgar Zolom and the WEAPONs have higher ones) and the Debug Room fields have fieldIDs between 65 and 112. This permits one to warp into the various Debug Rooms, among them the Debug Room lobby, from which one can access all other Debug Rooms, by simply escaping from the according world map battle and then Extended Battle Mode Warping.
Here is a list of the Debug Rooms, their fieldIDs, the equivalent encounters and information on where to get said encounter:

Debug Room - fieldID/battleID - encounter - location, chance to get encounter in location
#00 (lobby) - 65 - 2 Nerosuferoth, 1 Formula - Junon Grass, 1/4
#01 - 93 - 4 Beachplug - Corel/Gold Saucer/Gongaga Beach, 1/4 each
#02 - 97 - 3 Flapbeat - Gold Saucer Grass, 21/64
#03 - 94 - 3 Beachplug (Side Attack) - Corel/Gold Saucer/Gongaga Beach, 1/4 each
#04 - 95 - 2 Spencer - Battle Square (impossible to activate)
#05 - 96 - 3 Spencer, 1 Flapbeat - Gold Saucer Grass, 11/32
#06 - 98 - 1 Chocobo, 2 Flapbeat - Gold Saucer Chocobo Tracks
