Help with Master System palette on YY-CHR

[ticoeteco23gb]

I'm trying to rip sprites from a Master System game, and YY-CHR is a recommended tool on the wiki, but when I open the game, the pallete doesn't match the colors from the game. I try to load the pallete from the emulator state (open MEKA, save state, YY-CHR menu > "Pallete" > "Load Emulator State..." > open save file), but it doesn't do anything. The pallete doesn't change. I'm not familiar with ROM editing, tiles, and other technical stuff, so is there something that I'm missing? I might end up just going through the screenshot route for ripping this game.
