[Feature] Gen III - Change Player Location

[demonkingw21-ai]

is there a way to change the player location?

@demonkingw21-ai That option is currently available for some games, in the Trainer tab. Which game are you trying to change your location in?

Pokemon sapphire so i can get from the 2nd floor to the top of sky pillar

Gotcha - I'll look into this.

[codemonkey85]

Thanks for the details! Two things here:

For getting up Sky Pillar right now: In Ruby/Sapphire, Sky Pillar's cracked floors can only be crossed on the Mach Bike — without it (or if you stop pedaling) you fall through to the floor below. Make sure you have the Mach Bike from Rydel's Cycles in Mauville and ride it straight up the cracked sections. That should get you to the top without any save editing.

On editing the player's location directly: The Current Map / X / Y / Z fields you may have seen are only available for the Gen 4 games, because that's what PKHeX.Core exposes. For Gen 3 (Ruby/Sapphire/Emerald/FR/LG), PKHeX doesn't expose the player's position or warp data at all, so there's currently no safe way for PKMDS to offer a 'change location' option for those games. Adding it would mean raw-editing the save's warp bytes by hand, which PKHeX deliberately avoids since it's easy to corrupt a save that way.

So for now the Mach Bike is the way to go. I'll leave this open as a feature request for Gen 3 location support, but it's a bigger lift than the Gen 4 version. Let me know if the bike does the trick for you!

Following up with some research on what a player-location / warp editor for Gen 3 would actually take. Documenting it here so the plan is in the open.

Where the data lives

The Gen 3 player location is stored at the very top of SaveBlock1 (PKHeX surfaces this as the writable SAV3.Large span). The layout is identical across Ruby/Sapphire, Emerald, and FireRed/LeafGreen — verified against the pret decompilations (pokeruby, pokeemerald, pokefirered):

Offset	Field	Type	Meaning
0x00	pos.x	s16	player tile X on current map
0x02	pos.y	s16	player tile Y
0x04	location	WarpData (8B)	which map the player is on
0x0C	continueGameWarp	WarpData	where "Continue" drops you
0x14	dynamicWarp	WarpData	last warp tile stepped on
0x1C	lastHealLocation	WarpData	last Pokémon Center / home
0x24	escapeWarp	WarpData	Dig / Escape Rope target

WarpData = { s8 mapGroup; s8 mapNum; s8 warpId; (pad); s16 x; s16 y } (8 bytes).

• warpId == -1 (0xFF) → the game drops you at the WarpData's own x/y.
• a valid warpId → you appear at that map's predefined warp event (a door/stairs), ignoring x/y.

On load, the game uses continueGameWarp when the continue flag is set, otherwise it falls back to location. So a reliable teleport sets both location and continueGameWarp to the same destination.

Planned approach

1. "Unstuck" button. Copy lastHealLocation (0x1C) into both location (0x04) and continueGameWarp (0x0C). Your last heal point is always a valid, reachable spot, so a stuck save lands safely back at the last Pokémon Center / your home. No map database, no softlock risk.

2. Raw warp editor (optional, power-user). Numeric mapGroup / mapNum / warpId / x / y fields — mirroring how the Trainer tab already exposes Gen 4's raw Current Map / X / Y / Z. Clearly labeled as advanced.

3. Upstream (longer term). Propose a typed WarpData/location accessor on ISaveBlock3Large in PKHeX so this isn't raw-offset editing. A full map-name database is a bigger ask and would likely stay on the PKMDS side.

The problem is I can't do the bike puzzle, hence why i'm asking this question

On load, the game uses continueGameWarp when the continue flag is set, otherwise it falls back to location. So a reliable teleport sets *both* location and continueGameWarp to the same destination. Why PKHeX doesn't already offer this PKHeX.Core exposes the pos X/Y (via ISaveBlock3Large.X/.Y) but *not the map identity* (location at 0x04) or the warps. And there's no map-name table to lean on — PKHeX's Gen 3 location list is *met-location IDs*, which is a different numbering scheme from the overworld mapGroup/mapNum. A friendly "pick Sky Pillar from a dropdown" picker would mean shipping a brand-new mapGroup/mapNum → name dataset sourced from the decomp's MAP_* constants. Good news: none of that blocks a fix. SAV3.Large is public and writable, and the edit round-trips correctly through PKHeX's sector-write + checksum logic on export. Planned approach *1. "Unstuck" button (the actual fix for this issue).* Copy lastHealLocation (0x1C) into both location (0x04) and continueGameWarp ( 0x0C). Your last heal point is always a valid, reachable spot, so a stuck save lands safely back at the last Pokémon Center / your home. No map database, no softlock risk. This is what resolves being stuck on Sky Pillar. *2.

A full map-name database is a bigger ask and would likely stay on the PKMDS side. I'll start with the Unstuck button since it directly fixes the Sky Pillar situation. — Reply to this email directly, view it on GitHub <#971?email_source=notifications&email_token=CFTYZ3QPYP745A6KEWWUK4T47LIPVA5CNFSNUABFM5UWIORPF5TWS5BNNB2WEL2JONZXKZKDN5WW2ZLOOQXTINRYGI2DAMRZGAY2M4TFMFZW63VHNVSW45DJN5XKKZLWMVXHJLDGN5XXIZLSL5RWY2LDNM#issuecomment-4682402901>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/CFTYZ3Q3BKHBVF4JJTZZQC347LIPVAVCNFSNUABFKJSXA33TNF2G64TZHMZTGMBUG4YTEOJQHNEXG43VMU5TINRRHEYTCOJTHE3KC5QC> .
