Title: Sonic (NES) - Edit Demo Mode Sequence
Post by: sics on October 29, 2020, 06:46:29 am
Hello, I would like to try to edit the demo sequence in my hack ( Improvement Vol.2 (RHDN Project Page) (, but for this I need to find where this information is stored and to be able to analyze it.

The only clues I have so far are two memory values ​​0x0000f2 and 0x0000f3, one of which establishes a countdown that defines the duration of the action that Sonic is executing and the other defines which is the action that Sonic executes, respectively.

I have tried to help me with the debugger, but not knowing what kind of data I am looking for, I have failed, so I request that you help me steer myself in the right direction to meet my goals, if you have read this far, thank you very much :thumbsup:
