[Sega] Sega CD, 32x and Megadrive shaders

There's a parameter error in the shaders on these three consoles; strangely, it doesn't happen with the Master System, but these three end up looking odd, with jagged edges, something that doesn't occur with the others. P.S: It's quite noticeable in the lettering and outlines of the eyes. <img width="2468" height="1853" alt="Image" src="https://github.com/user-attachments/assets/6e9bfb6e-a1a5-47fc-a76f-186c913ea69f" /> <img width="2468" height="1853" alt="Image" src="https://github.com/user-attachments/assets/d2ef0c58-c663-4c4e-bf87-7ed6c4b23083" /> <img width="2468" height="1853" alt="Image" src="https://github.com/user-attachments/assets/4e81c7b1-d66d-4d4b-838b-e6e197390e8c" />
