1)What is the building supposed to be?
Hey at least you're still working on this Thanks for the update you've been gone for like 2 months and didn't post here hahahaha
Dharma is probably supposed to be Daruma, and Frog is very likely Gael. Gaeru -> Kaeru = Frog.
Link works fine, but afaik the game keeps a cache of your current map in the save file, so if you don't have an earlier save after you replace the map files, you'll have to restart (Just plug your current save into a save editor, copy the values, then paste them into a new session).
I just want to tell you that the fact that you want to translate the whole spiral legend series is probably the best thing I've ever read, you are literally my hero
I've played them all through a translator. 2 is a direct prequel to 1 being the ancestors of the first game's characters. They also share some important immortal characters (like a vampire lady) through multiple games. The MC's journey in 5 is directly inspired by the main plot of 4 (5 MC having a dragon curse he wants to remove and 4 making a big deal of fighting a dragon became a story that 5 MC heard of). 3 takes place across the sea from some of the countries in the other games but I don't remember which other than it's referenced both in the later games and earlier games.
Sounds interesting, guess I should have started with the first one then lol, though the part about 2 seems wrong, I mean, ive seen the portraits for Carl and Tilm from the first one in the files so I assume they make some appearance, Tilm's is also in 3 along with Helga's, and the protag of 3 and the two heroines, along with another character named Ruri appear in 4, and I can't be certain if this is the same character but in 2 there's someone named Halberd who I also saw in the enemies list in 4.
About 2, like I said the people from 1 are descendents of the people from 2. The blacksmith Tilm in 1 is descended from Tilm in 2. Tilm 2 is a blacksmith with a small shop but grows famous after being one of the heroes. Tilm in 1 is descended from a dynasty of master blacksmiths Tilm 2 founded after the events of 2. Tilm 1 is also a side girl you can lewd but not gonna go too far into that. She just shares her ancestor's name. Helga from 1 is stated to be descended from the redhaired heroine in 2. They're the same family.
That might not be the case with some of the portraits you've found since I don't remember every little detail of all games, but Expiacion doesn't always use every animation and art piece you can find in the files. He talked about it a bit when finishing up the last Spiral Legend V update on his pre-cien blog, though I don't think that exists anymore due to the migration. He sometimes has ideas but abandons them halfway and just leaves some leftover unused assets. I decrypted (and modded and did small translations) each game after I beat them and there were some I was never able to find places for. I might've missed something but I was pretty thorough scrubbing it for missed content.
So it's a reused portrait in Tilm's situation, and I guess for 2 they went along with the true end, which I'm gonna guess is a harem one, since it says on the dlsite page that there's no actual NTR in that one, only defeat scenes with some cucking-flavoured text. Though I guess it makes sense that some stuff would be reused, I mean Antera from 5 uses the same portrait as another character in 2, the only difference is that the one in 2 has red hair.
Yeah, it's reused assets and I think the true end is implied canon for every game because even the "normal" NTR and single Love routes usually leave the game's kingdom vulnerable to another attack or more problems because the cause of whatever big bad was summoned can only be discovered and dealt with on the True End routes. That or the non-True routes are pyrrhic victories.
