Phantasy Star Maps
Phantasy Star's dungeons use a first-person perspective, which means they almost need to be mapped for you to have a chance of getting through them. This was in fact probably the first game I extensively mapped and needed to to beat it (as opposed to mapping for fun, or to find hidden items).
Unfortunately, that also might mean that my notes are a bit primitive. They might not be very self-explanatory. I'm not even sure how much of them I myself would understand right now. I'll have to replay the game sometime and perhaps annotate these notes more. I also can't guarantee these maps are in any kind of order, or are complete, though I assume they roughly go from the beginning of the game to the end.
I also made a mistake while mapping Bala Malay. Basically, I made it near the top of the tower, and then started going back down, thinking I was mapping new floors. Notice, for example, on map 19, the area that has staircases 2 and 3. It seems to be identical to the area on map 33 with staircases 6 and 7. I also made another mistake that prevented me from noticing this earlier.
I obviously got that straightened out eventually (or I wouldn't have been able to beat the game). I thought I made more notes on my maps about that error than I seem to have, though. Hopefully, it's not too confusing. I'd assume the later maps are more likely to be accurate than the earlier ones.
This is a short little dungeon. It might be the sewer or something from the beginning of the game:
