No.
Master Edition -- the original game -- was made by NovaWizard and released only on the forums of Sonic Retro:
this thread. As the original creator of the game, there is high likelihood that he would ask a moderator to unlock the thread and post updates there.
Without NovaWizard's consent, VegaLTE/mok45 made edits to Master Edition and tried to pass it off as if he did everything. GT Koopa was the first to notice (see his posts
here, and the thread
here). He is not welcome to SSRG, and yet, he is using their logo as if he has their approval.
If he is saying he made Master Edition 1, he is lying. Unless he is calling his first unauthorized edit "Master Edition 1", in which case he is technically speaking the truth about this, but glossing over the fact that he stole someone else's work, edited it, then tried to pass it off as his own.
