Gotcha. NESDev is another forum dedicated to NES development and homebrewers. For the past decade NESDev has hosted a homebrew competition where brewers submit games, demos, apps, tools, etc. and entries are all featured in the follow up volume of Action 53 available from Infinite NES Lives.
We have some overlap with members there but it's more of a technical forum with tons of dev talk and resources. You can always check out the progress of the competition games and play the early builds too. There have been some notable entries that have gone on to full releases. Nebs N Debs and Twin Dragons come to mind.
The forthcoming Action 53 Vol 4 features entries from the 2017 and 18 competitions and will include Streemerz' return to physical cart. The entire package is also available for download here.
