Loading Save into Default Map

Azure_Keys · Jun 5, 2019

I'm having a bizarre issue with a PokeCrystal hack I'm working on. Whenever I use the in-game saving function, close the ROM, reload, and chose to continue, I will always load into a specific location, directly in front of the Pokemon Center in the "first city" map. This is the first SPAWN constant beyond the initial SPAWN_HOME and SPAWN_DEBUG constants. This occurs even if I save the game immediately upon starting, without even leaving the initial Player Bedroom map.

The Player Data seems to be saving into/loading from sram fine, as the player name will remain unchanged, it's just the map location info that isn't loading properly. I'm assuming that there's some routine that loads a default spawn if no map data can be loaded, and I can't quite figure out where it might be. Any help/advice would be greatly appreciated, thanks.

Well, I feel silly, I just figured it out not an hour after making this post...

Leaving this here for anyone else who may have made the same mistake. When I replaced all of the vanilla PokeCrystal maps, I'd gone through and swapped out any of the old SPAWN constants for maps that no longer existed. In fixing the intromenu.asm file, I mistakenly assumed SPAWN_LANCE was one of the SPAWN constants I'd removed, and replaced it with SPAWN_HOME as a placeholder. Turns out that, despite the naming convention, SPAWN_LANCE is a wram constant, and I never removed it from the game. So if you're like me and are replacing all of the vanilla maps, leave the SPAWN_LANCE and SPAWN_RED constants alone.
