I have one concern. Submissions using secret codes are well and good as long as it is clear that they are using a secret code/character AND if it openly available to everyone. Secret codes by definition are NOT available to everyone. Any secret codes need to be published and be made freely available to keep the 'level playing field'. I'd be upset if someone was getting high scores using Takuma and I couldn't compete because I didn't know the secret code. Perhaps we should insist that any inp using a secret code must also have a accompanying 'howto' to enable the secret.(posted 9309 days ago)In some cases secret codes may need to be banned or submitted games put into a separate classification. E.g. any invincibility code ought to banned. Codes like "powerup" in bubble bobble give a huge advantage and need to be classed differently.
We will probably have to access each case as it comes.
As for KOF and SF2 secret characters, I'm ok with them being used as long as the codes are freely available.
