currently im making a nes nametable viewer in php.. i read jjj.chr, and using nametables exported by rocknes, actually i made up nametable using 61440 (TD) tags. i am reading smb very good.. v0.1 takes around 20 minutes, but version 0.2 takes around 12 now.. im working to increase the speed of my code.. my second goal is making the sprite viewer.. for what???.. did you notice how small are titles of nes viewers??.. with my nametable and sprite viewer you can see info in .nam about any game.. ok.. im going to work..
good luck
