Let me get away from the LGP/E stuff for a moment and go back to Gen 1

Long story short, if I were to facilitate a money match between two people using only fresh copies of Red/Blue, besides the Missingno glitch, are there any other glitches I should be aware of to watch out for that would provide an unreasonable advantage to one player? I'm aware of the Mew glitch and am contemplating in keeping that in.
