I tested all the repros I have that aren't sealed. I have repros and homebrews for a few different systems and I really wanted to put together an acurate list to help people out so please feel free to add to this thread.  

Here is a link to the Google Doc, Please add to it

I made sure these games actually loaded and played correctly, as some would load, but not play.

Games on the left didn't work, games on the right did.

What homebrews did you try that worked and played?

The ones on the right.

For your google doc you should add columns for retron version. Assuming they do system updates it will become far harder to keep an accurate list.

Nice initiative. Hopefully this will be sent to Hyperkin's management and actually dealt with.

I added some titles that I feel should be on there and tested. Among the most popular and arguably best hacks like Mario Adventure, Zelda Outlands, Mr. Gimmick + Return to Dino Land and Parallel Worlds Remodel

I figured for iterations I could add another sheet, columns would work too. I have left the doc open for editing. I trust the community here to only put in tested info

Nice start, interesting to see what is and isn't working. You kind of have to wonder not so much with the NES but the others why they don't. And even then some people do carts up differently with new boards of chop shop mutilation of another game so that may affect loading/playability too maybe.

Yeah, by no means do I think this list will be consistent for everyone. The quality of work and how the work was done is going to make a difference I am sure.

I think he meant which actual homebrews were played as opposed to repros?

Hell yeah. Glad to see Fix it Felix works. Hopefully Mario Return to Dinosaur Land does too.

One of Hyperkin's tech guys has taken notice of our thread and spreadsheet. He responded to somebody posting it on their fb page. He said most of the repros on this list that dont work will be made compatible with the first firmware update. He said they're already working on patching in repros and homebrews that people are letting them know don't work.

This is one of my favorite features for the retron 5. For the other clones, if a homebrew didn't work, you were basically fucked. Thank goodness for the OS.

Like I said in the other thread, exactly how do we know this guy is actually a Hyperkin tech guy?

The post is buried now, but it was confirmed a while back that all of the "hk" accounts (hk marketing, hk tech, hk sales, etc) are official accounts. It seems Chris Galizzi is the only Hyperkin employee who uses his personal facebook for hyperkin doings.

this is good to hear. Shows they give a shit. Happy to see that.

Might be a good sign to put to bed a lot of garbage of people blowing hot air about this thing without much just cause since this is an entirely beast from the usual defective system on a chip junk out of China people like them sell.

But it IS from China.

Glad someone is doing this. I have heard through the grapevine that Camerica NES games including Micro Machines do not work. Hopefully they get this fixed.

Homebrews that use brand new mappers like Battle Kids or Study Hall, will likely never work.

I never said it wasn't, just that it wasn't the usual subpar system on a chip junk which won't run various carts, mishandled audio and video(color) issues and the other popular complaints about such things. This one has the potential cheap Chinese junk or not with system patches to clean up a lot of stuff those garbage past clone boxes didn't bother to do.

Homebrew like battle kid and the like could work. It would depend if bunny shared the info, or one of many credible people out there with engineering talents to take a look at it and figure it out themselves and send that data to Hyperkin if they don't take it upon themselves to do it (less likely.) I think if they're approaching this on facebook already talking about firmware upgrade one to get stuff like this going, they may be seriously for now taking in complaints and wanting to address them to put most of the legit complaining to bed to just leave the hot air filled trolls with less to complain about.

It's been done already. Study Hall and Xmas 2013 have been assigned iNES Mapper #30. I have been in correspondence with the guy who figured it out, whose identity will remain a secret unless he comes forward to take credit. Fact is, the newer boards which use flashed based save data do not work the way normal SRAM games work. They actually have more in common with the FDS system in that regard, since the game data is stored on rewritable media. For example, Study Hall stores the high score tables in bank $06. To properly emulate such mapper, it is necessary to write changes back into the ROM. This would cause a lot of headaches for Hyperkin, and you definitely would not want to write the save file back to the cartridge, because the entire ROM is the save file. One wrong bit and the cart could be toast. However, during normal game operation, only the bank which contains the save data gets overwritten, so the chances of bricking the game on properly functioning hardware, original or clone, is minimal. Another issue with running a newer flash based game on the Retron5 is the CRC value which would change every time the "save" data is updated. Assuming the Retron5 uses CRC hashes to identify the game cart, it would create a new "unknown" entry every time the cart is inserted with updated save info. This is probably another reason why the Retron5 can't be arsed into supporting the Famicom Disk system.

It's running this one just fine after the update! I'm stoked.

Finally! I got about 2/3 through this game and got stuck. You don't know how long I've waited to be able to beat this game. Now I finally can, with save states!

I dont know. I had a retron 3 a couple of years ago. Broke really quickly. NES pin connection was shitty. The SNES went out. Only thing that works on it now is genesis. All these retron systems imo are not made to last. Looking forward to see Bunnyboys. I know that will be a quality hdmi nes system not built to fail.

quest if his did SNES too and had save states I'd be all over it, but I really just don't need an HDMI NES system as I'm not that hard up for super sharp graphics as a selling point as I have no use or interest in scoreboard. I know their past products were awful but the durability of the things have improved slowly over time. They seem interested in selling this thing at a higher price point and I think they're trying to shoot for something that'll last a bit longer than a $40-50 throw away junk on a chip system.

Awesome review, thanks. I'm glad someone likes the controller. I guess these other gamers were turned off by it because it was too clicky or wasn't mushy like the vintage controllers. Just because it wasn't what someone expected doesn't equate to suckage.

BTW, Have you tried any repro/homebrews? I guess NES homebrew/repro is the achilles heel of this console due to mapper hell. Even so it seems Hyperkin is dedicated to adding support to get more games working through firmware updates. Anything that doesn't use obscure or custom mappers should be possibile to get working in theory. Oh, and no flash carts, but doesn't that take away from the spirit of collecting?
