I'll try to keep this updated as new information comes out and actual release dates change. Any corrections? Unless a specified month for upcoming releases has been stated, I've left it off the list until further info comes out or the product actually ships, i.e. What Remains carts which are in current production but they haven't said when they'll ship. 2019 seems to be the easiest place to start in regards to chronology.

I think this would be a good idea to have a thread of the new NES homebrew and have it sorted year by year like your doing. Each year have a new thread with listed titles and links.

Added PROTO DERE .NES to the January releases.

These were released in February http://nesdevcompo.nintendoage.co...

I plan on having the website updated soon.

Is there any news on development of Action 53, Volume 4?

Added Bushido Bomb for June and Battle for May.

Maybe? I know that the art is still coming in.  Not sure if it is completed yet.  I haven't personally been in charge of the cartridge portion of the project, but maybe I need to step up so the 2017 people can get their carts, and things can get rolling on the 2018 cart.

Then there is the "master" Action 53 cartridge project.....

So basically it's all a mess.  Tepples is to busy with paid NES gigs to work on it (even though it has been his baby from the start), but I digress.

Added Melo-Jellos 2 to January

Removed Draiocht: The Challenge of the Druids from June as it didn't end up being released that month. Will add it whenever it does eventually come out rather than continuing to bump it to the next month.

Removed Basse Def Adventures from May. What I thought was a release was actually pre-order. Release planned for end of summer.

Micro Mages carts were in fact released in July. Draiocht was released in July. Candelabra didn't ship in July due to parts, hoping for August. Convention Quest releases Aug. 9-11 at Let's Play Gaming Expo. Cross-Strait Independence released in Taiwan for Famicom in early August.

Added Miner to August

There's also the game made for this year's Midwest Gaming Classic that is still available in their shop. Bovinium Quest:

Thanks! Now we finally have an entry for April.

Anyone have more information about this game?  I read the article and watched the trailer, but I can’t gather what the game play is.  No other videos on youtube. 
 
 

Mine arrived over the weekend (same day as I posted that picture of my collection).

It’s an arcade-style game. Imagine a bunch of platforms and ladders. At the center on the ground is your cow who is being slowly abducted by aliens hovering over the gap between the top platforms. You have to hurry to reach a series of objects that will block the UFO’s beam and save your cow while avoiding snowballs that roll across the platforms. There is a time bonus for how close to the ground the cow is when you finally block the alien beam.

 

It's a single-screen arcade platformer type thing. I can't remember the details (I only played it for a minute or so), but you climb ladders to avoid things, trying to complete the level before your cow gets abducted.

Edit: I guess Scrobins09 beat me to it. What he said. I guess I'll add that it's fairly slow-paced for an arcade platformer.
 

Is it cart only or come with a box? I've seen pictures online of a box but the page you order from makes no mention of it...

I received cart, manual, and box.

 

Added Mutant Sewer Girls to August

Added Wampus to February and moved NEScape! from September to August.

PROTO DERE NES - this is a game made on the NES Maker.

Thanks, was able to verify that, just put a star next to it.

Jay and Silent Bob Mall Brawl is estimated to be shipping December from Limited Run Games.

Thanks! Added it. My impression is the digital version is not an actual rom file, is this true?

Removed Candelabra Estoscerro from August. Will add it back once we get more details on when it will release.
