That text was copied from the official Street Fighter II, which initially lead me to think that MFII came out first and then Yoko edited the sign for SFII. However, MFIII does the same thing and that came out in 1993 so I'll say SFII was first.
Edit: Scratch that, turns out MFVI uses the Yoko sign. My guess would be that Yoko made SFII first, edited the sign for MFII and MFIII and then took the background from SFII for MFVI. A wild guess, but I wouldn't say farfetched.
