Silly question: where is the code and/or issue tracker for BlepStation?
I see that there is GitHub page existing as general-purpose WizDen-upstream-tracking game repo, but it seems to be rather old and issue tracker here is turned off.
The link you posted is for vanilla content, its purpose is to closely mirror upstream’s content at specific checkpoints (with the MV-needed changes already merged in)
BlepStation is a closed source fork, so the source is not publicly available. Blep’s issue tracker is very sparse and a mixture of ~5 tasks on github and a big text file on my local machine 
That’s kinda sad, as it currently the only ways I can contribute to BlepStation would be leaving adminhelp messages about bugs or interacting with WizDen again.
Consider releasing BlepStation game code publicly. Perhaps not on GitHub, given the no-fun-allowed nature and repo bans problems of GitHub. I’d not mind WizDen being able to merge back bugfixes applicable to them. If they want, that is. Don’t want to touch their stuff otherwise.
FYI you can send code patches if you wish to send code to blep, there is some instructions for this on the wiki
