That situation is kind of interesting, I've been discovering stuff about it today, other people probably already knew... It's actually SYS2-C68 on this board and the dump matches the rom named that way in some Super World Stadium sets. I'm not sure if all Final Lap 3 sets use this one or if some of them used the SYS2C65C one or what, but it's definitely correct on this set for it to use the C68 one. I've powered up the board and it runs perfectly. The chip isn't anything special, any programmer can read it, I think it might have just been skipped over during some dumps because it's labeled funky? I don't know. This chip isn't an MCU, it looks like it's data for the MCU.
