I'm trying to work on my tracing/debugging skills to find level data and I'm having a bit of trouble. What's the first thing I should set a breakpoint on, when the tile data is read?

Tile data's not as important as the map data. Start with that.

...Mind you, I've never actually done this kind of thing before. But it makes sense.

I guess I wasn't clear enough. Map data is what I'm trying to find.. I think. I kind of wanted it to be a secret, but whatever, the game is Zelda: The Minish Cap.

Find out where the map data is stored, then check for writes.

VBA-SDL-H will break on writes even if they're performed by DMA; not sure about No$GBA, but hope it helps.

That's the thing, I need to find where the map data is stored. Sad
Any tips on that?

Hold on, I think I found an offset for the Shoemaker's house a while back.  However, the level data is compressed, which shouldn't be a shock to anybody.

Try 432F90.  I forgot to lable my bookmarks, but if that's not it there are 3 more I have marked down.

At first glance I thought everything in the game was uncompressed, but I think some of the tiles are, which is why I haven't been able to find them to trace to the level data. Thanks Jigglysaint, I'll check that offset out. And by compressed, do you know what kind of compression it is? I haven't been able to figure it out.

Edit: Yep, that's the right offset alright, thanks a ton! Now just to figure out this compression..
