New cores are not automatically added to RetroPie, someone has to add it - either one of the developers or by submitting a PR (pull request, request to change) to the Github repository of the project.

@Shandower i do read posts, but considdering that you wrote "out the box" i assumed you installed xarcade2joystick via the retropie setup script. either way, if this works for you, then it doesnt really matter anyway

@mitu said in Can't seem to get Netplay to work: @mikespie Please add more info about your system - https://retropie.org.uk/forum/topic/3/read-this-first. The core means which emulator are you using for the running the game. You need to use the exact version of it and also the exact ROM on both systems. Since you're running a Megadrive rom, the core should be either lr-picodrive (I think this is the default) or lr-genesis-plus-gx (see the Megadrive docs). Thank you for your response, sorry for not providing all info. Just from your post I was able to figure it out and have Netplay working / connecting now! However, it seems as though the controllers do not work in a lot of the games while on Netplay. I have tried using different emulators to no avail. An example is Street Fighter II for Genesis, Player 1 controller works fine, but player 2 controller doesn't work at all. Tried a keyboard as well, both which work fine not in Netplay. My system is a CanaKit - https://amzn.to/2Taj5jf PI 3 B+ w/ 2.5A power supply RetroPie V 4.4.4 (skyscraper-pr6-v3) Built from premade SD image on RetroPie website I have a USB keyboard, mouse and controller hooked up to it Controller is working great outside of Netplay, it's an "EasySMX 2.4G Wireless Controller" and also a Geeekpi SNES USB controller Emulator is lr-genesis-plus-gx Thanks again!

Anyone know if its possible to bind keyboard arrow keys to the d-pad? I can only think of a couple games that would benefit from this, but would be curious if it's possible. The list of possible inputs in Retroarch's menu don't include these sadly. This port otherwise works great on my Pi3B with an SN-30 Pro, thanks for the hard work on this!

yes that I know @DougA, but I do not wish to launch the games every time but the fire via Notepad ++ @mitu I'll try to see what I can do with emulators.cfg to scale my games

I understand :/ per game it is then... :)

the post above has some merit.. "... I immediately clicked "verify only" and got the error "Verification failed at sector: 8192". Then I tried the following: READ the contents of the SD card back to a file TEST.IMG. WRITE the file TEST.IMG back to the SD card. Run "verify only". This time, the verify succeeded without any errors." I performed the same steps and got the same outcome. It took 3-4x as long this time to read,write, verify the image. Some of the NES Roms now play, still working on it Thanks again for everyones help :)

today it seems that this core supports the borders of the super game boy. has anyone tried it? would it be possible to add it? unfortunately mgba supports borders but not palettes, while gambatte supports palettes but not borders :(

@alexis-puska thanks for the reply, can you give me some instructions on how to instaall this, sorry i was following a guide before and not sure what i need to do. Thanks also does your version have the saturn wide screen massive map? Thanks

@meleu thanks friend but dont work, i try to create manually in winscp the file emulators.cfg and configurated and works but need to edit manually the file outside , if i try to modify in runcomand inside raspberry dont work and show errors again.

@edmaul69 Looks like it's an Retroarch bug. no mouse / keyboard support #2128

@Slugz https://retropie.org.uk/forum/topic/3/read-this-first

it's not beyond a possibility. uoyabause runs well on arm phones of similar specs. the problem is that the pi only has GLES 2. 3 is required for it.

I read it but I wasnt successful there is no info for supervision setting up rom folder and setting up system file
