SM mapped area missing/corrupted

[Josephur]

Console or Emulator: Snes9x 1.55

Original Filename: Not available (renamed file, sorry) Seed: Not available

Item, Entrance or Custom: Used fortune teller near links house to return to SM after finding Gravity suit in ALttP

Description of problem: First I realized I've already been to this area before, why is the map data missing, then upon closer inspection some of it was there, but then if you look at the downward hill in the map, only parts of it in the look mapped (purple not blue), which is impossible.

See attached screenshot.

If this is a v9.2 seed, then it is possible the routine to recall the map data isn't accessing the right data. It will be looked into.

Have experienced this 3-4 times over different seeds now (9.2), just wanted to update you that it happens pretty frequently. Not a huge deal for tournament style players, but for us casuals knowing where we've been is a huge help.

Can confirm that this happens to me on v9.2 as well, over a few seeds. I'm using an sd2snes and 1chip SNES

[lenophis]

Yeah, it has been confirmed. I know why it's happening, just haven't been able to nail down a fix yet. Coming soon!

[Josephur]

Just want to follow up to add that this is still happening in V10.

Is the problem that some map data is getting ported from one area to another when doing a game warp?

[lenophis]

We have found out why. It should be fixed for v10.2. We're just testing it to make sure it works properly, and doesn't break anything else.
