hmmm, turns out the rom is not iNes2 headered so only need port mapper30 would do
but iNES2 really needs to be included, if the core is planned to support more mappers especially for homebrew games. Let me see what i can do as far as by “PR”.

Great! When would we be able to start using this in RetroArch / RetroPie?
dunno, still got a PR pending.

Oh. I see your fork on github but not a PR for this. Where is the PR? Was
going to subscribe to get email updates fron github. 
what OS do you have? i can probably make one for windows x64 or ubuntu x64, else you probably have to compile yourself. i ddnt submit PR yet regarding the mapper, not have uploaded it to my own git
if you know how to compile yourself, this is the commit that has mapper30(this is an experimental build though as it has options for sound quality and sound rate for some tests i need)
if do not want to compile, you probably just have to wait that someone does update the core.

Yeah I was just wondering as a ballpark estimate how long it usually takes for changes like this to make it upstream so they show up on all versions. I use Windows, Android and RetroPie on Raspberry PI 3.
Sorry for the Off-Topic… but this Mystic Searches project sounds very exciting 
I’m looking forward to trying it out!
I didn’t realize there was an active NES homebrew community. I just found this other one out: http://lizardnes.com/ (demo works fine with FCEUMM) Are there any other examples of good “modern” NES homebrew games?

Dpad Hero is a guitar hero style homebrew game for the NES. It also got a sequel called Dpad Hero 2 I think.
Final Fantasy VII got an NES demake from China which was translated into English and expanded to include most of the original game’s story and characters by rom hackers. That one’s probably the biggest NES ROM I’ve played.
Thewit.nes is an NES demake of The Witness by Jonathan Blow. (At least the opening areas)
ROM City Rampage is a super impressive proof-of-concept demo which shows that a game like Retro City Rampage with smooth 4-way scrolling was totally possible on the NES.

Oh and if music carts count then there have been a few of those.
MOON8 is a chiptune version of Pink Floyd’s Dark Side of the Moon.
“8-BIT MUSIC POWER” is a thing from Japan but I don’t know if anyone’s dumped the ROM.

Woah woah !!!
Thank you, I really need to check those out, I’m getting every one of them 
Very interesting the “making-of” video of ROM City Rampage.

Also check out Super Bat Puncher Demo. I hope the author will flesh it out into a full game because the demo is amazing. Great music, responsive controls, metroidvania gameplay, silly humor.

Mystic Origins got an updated bugfix version. http://steamcommunity.com/sharedfiles/filedetails/updates/880758073/1489588191
Any update on the status of this?
the game seemed to have changed… i cant find the rom anymore in jar.
I’ll look at it after work. I have a backup of the old version if that’ll help.
The guy has said he’s probably going to attempt to obfuscate the ROM in the digital download on Steam for his full game. Maybe he’s testing that now. I find it really annoying that I can crowdfund a new NES game and then not get the ROM. That shouldn’t even be a thing IMO. I would not have backed it if I knew there would be flirting with DRM going on.
I just checked the jar he currently has up on his Steam page and found the game.nes inside the “mysticseraches” folder inside the jar just like before. Maybe try downloading it again?
Hey everyone! Just accidentally stumbled upon this thread…wow! It’s really neat to find complete strangers online talking enthusiastically about the project (usually, when i happen upon something, it’s trolls trolling). You guys rock! I wanted to let you know I signed up for this forum and am commenting so that I can let you know I support your efforts and if there are any questions you have for me directly, feel free to ask!
Additionally, I noticed some of you are just now finding out that there is a NES homebrew community…that is one of the main reasons we started this project…to both draw attention to the fact it’s a thing, but also really show a vertical slice of the level of investment it takes to bring one of these games to life (compared to just creating a modern game with a retro aesthetic). I think you’d all dig the documentary (The New 8-bit Heroes) which was the complement to the game you guys are discussing. We just posted the trailer - check it out here if it sounds like something you’d be into (this trailer is specifically tailored for social media, btw, which is why I’m sharing the FB link)!

Feel free to get in touch with me here or directly (probably more reliable) at [email protected] with any questions you might have or if you would like any info that you’re not finding. You guys all rock

I tested and Mystic Origins now works! (tested in RetroPie on the Raspberry PI 3)
Thanks for adding this!
Follow-up:
I was wondering if you are still playing Mystic Origins… is this game still being developed?
