To be honest I didn't understand a thing, how can I edit the 0x3ec38 and 0x3ec3d anyway? Quote from: SpiderDave on February 28, 2017, 03:58:01 AM

The first line has our memory address for lives, the second and fourth lines look like drawing locations to me. The breakpoint that stops at 0x03ec49 (I have rom offsets checkbox checked) has some of this close to it, just above.Ġ3EC39:9D 1B 02 STA $021B,X $0253 = #$68Ġ3EC3E:9D 18 02 STA $0218,X $0250 = #$F8 It stops in 2 places, I look at them for a bit and see if I can find a reference to the lives, and maybe something that looks like a drawing location (0x20 and 0x50 maybe?). I go into the debuggerĪnd add a breakpoint for 0251, write. I search for that in the cheat search, get a few results, I try freezingĪ few of those and one of them makes the lives flicker (0x0251), so I guess it's part of the drawing routine. Open up the PPU Viewer, see that the tile for 9 is tile 0圆4. I load up game in fceux, use the cheat search to find a cheat for the number of lives, It's in the ram at 0x03c5, I freeze lives at 09.

This is a 'teach a man to fish' kind of thing so you can apply it elsewhere or to other gui elements. Well I didn't do *all* the work but here's what I did.
