I have now found and downloaded Overworld Spriter, Advance Map 1.92, Irfan View, PKSV, and unlz.gba
I heard they were good.
But there is one thing that I can't figure out about Advance Map.
I can't find Grosser Block.
I've heard about it but I can't figure out where it is in Advance Map 1.92.
I have tried right clicking and dragging like you are supposed to but it doesn't work.
