First time poster here, so I hope I'm in the right forum.
I'm drawing lot's of map when playing old RPGs on computers (PC/Amiga) and I'd like to use my computer for that.
I tried a couple of mapping software (CC3 for example) but they are aiming at producing nice looking maps, where I just want a 'functional' map for now.

I'm looking for something in the vein of what Etrian Odissey ( DS RPG) provides: Completely square-based, no size limit, basic tiles / walls / door / and notes.
Right now I'm still using graph paper, but I'd like to be able to play while mapping using a tablet (like a bamboo) at the same time

Does that kind of beast exists ?

Thanks in advance
