Anyone know of a SNES emulator with a memory viewer (vboy advance style, preferably)? Such a thing would greatly simplify the process of finding sprite addresses.
I tried to find a speed hack for Dracula X, thinking that if I found one that matched loopy's I would know I was doing it right, but no luck. It gave me a bitch of a headache; I'll try again sometime (this weekend?).


Snes9x/zsnes have debuggers but they are a headache to use (in my opinion). If you want to look at the SNES memory in pocket...er, snesadvance, it starts at 2000000 in VBA. (2001234=7E1234..)

Why didn't I think of that... I actually half gave the answer in my question (vboy advance style). That will make it a lot easier, thanks.

sephiroth2k: I just realised mario paint would benefit greatly from sprite following, if you're still taking suggestions Smile

This works pretty good for Super Mario World: 25%, +10, 0x96-0x1c, 16bits

For Final Fight I came up with 0x7e0d0a, but it follows opposite what it should (when sprite goes up, screen moves down, and vice versa). Leads me to believe that Final Fight (for some reason) could use an inverse following technique of some sort.

Can you find one for Flashback (U)?
It really sucks to have your player virtually invisible when at lower parts of the screen

1E6ACEBA|Flashback (U)|35848193|0|0|0|0|1900FD=EAEA,251E6=42FB
That helps out most of the graphical errors.

Try using my tutorial to find one yourself, if you don't have any luck I'll look tomorrow.

I don't follow either of you... Flashback probably needs difference following.

Ok, you should have figured this out, but...
These values are the addresses in which the sprite location on screen is stored. By following that value, the screen will scroll up and down as your sprite (that pretty picture of a plumber or whatever) moves. This is useful because the SNES has a different (larger) resolution than the GBA, which means not everything onscreen will show up on the GBA.
