Hello! I have been thoroughly enjoying this rom hack! Not often do you see a fully fleshed out PMD game! I am experiencing a constant Data Abort error crashes during Mt. Horn. I tried disabling some settings, but I can't turn off randomization to confirm that one, since it's only through Porygon2 at the guild instead of the one in front of the cave entrance. I can share a save file or anything if it helps, the farthest I've been able to get before a crash is Floor 12 before it errors out, other times it occurs by about floor 5-7.
I am using this on a modded 3DS, starters were Gible and H-Zorua. One post somewhere mentioned to ensure the .nds and .sav were the same name, which they were both listed as Explorers of Sky, so I changed it to Explorers of Alpha. Any information helps, I can also get a log attached somehow from the 3DS if that helps.
