This doesn't have much to do with speedrunning, but because I'm using BizHawk this feels like the ideal place anyway.
I'm trying to access the hidden character seen
in this video, and according to the uploader of the video, the total score (seen when you select "NAME" from the main menu and press select) has to be lower than 320. I really don't think I'm good enough at the game to accomplish that legitimately, so I figured I'd try using a hex editor.
Unfortunately, I have barely any experience with hex editing, so I tried brute forcing it for a while. While I was looking at the CIRAM as the game showed
the aforementioned total score screen, I figured out which addresses correspond to the numbers displayed and how to change them, but they didn't stay changed.
I think I'm only messing with what graphics are displayed, and not affecting anything deeper than that. So I was hoping someone more experienced can point me in the right direction. I'm not that good at concluding long posts like these, and something tells me anyone who wants to help will need more information than what I've provided, but hopefully we can figure it out.
