What are the hex codes for the bottom of the screen?

At 1:19 in the tutorial, Joe explains how to change the ASM to make the weapon icons change position on the screen. The only problem is, they're in hex code. My HUD is at the bottom and I have no idea how to make these icons appear down there -- I've just been stabbing blindly, writing the hex numbers I know with no results. How far down do the numbers go on the screen?

Good question! Basically hex is a base 16 number system (where as decimal is a base 10). So...#$00 - #$0F is like 0-15.

A NES screen is 256 pixels across x 240 pixels tall. In hex, that's #$00-#$ff wide, and #$00-#$E0 tall.

Hope that helps give you a starting point

No matter what number I put there, they don't show up. I tried clear at the bottom, they didn't appear. I tried slightly above the bottom since stuff on the very bottom could get cut off -- they didn't appear.

What do I do -- enter every single coordinate pixel by pixel until I get something that shows up? I don't have the time.
