Quick note - I needed to change

input_player1_l = "q"
input_player1_r = "w"

to

input_player1_l = "("
input_player1_r = ")"

as q and w are used for games with more than 4 buttons such as Street Fighter Alpha 3.

Will the quotation marks causes any problems for retroarch anywhere else @Floob

Thanks again

Shame you haven't had any responses to this or the post you made on the other fork too.

Been trying to get badlands working too until ibsaw this.

RetroPie Setup scripts and then install Kodi again.

I don't believe RetroArch supports non-merged sets. MAME itself supports non-merged sets but the RetroArch MAME cores do not.
So you need split sets with both parent and clone. More correctly, there is effectively no difference between split and non-merged, the emulator core will always look for a clone file in the clone ROM, and will always look for a parent file in the parent ROM.
There is no way to avoid this AFAIK.

it sure does support non-merged :) in fact, the recommended set for mame2003 is the 'mame 2003 reference set' which is non-merged, and easily locatable.

Ok, some progress!

I used ClrMamePro to build a non-merged .78 romset, using the .DAT link on the Managing Mame page here. I chose non-merged because sometimes I prefer a clone over the parent and only plan on loading maybe 50 games or so. But for now, I loaded the entire romset on my pi, and some games that didn't work before now work! 1941 works as does 1942.

There are still some games that don't seem to want to load that show as working in the compatibility list however. Most notable are all the CPS2 games and Neo-Geo games. I'm not too concerned about the Neo-Geo ones as I've already got those running great in Final Burn Alpha. I'd absolutely love to be able to play the CPS2 games though.

All of the CPS2 games that are supposed to work, launch to a black screen, then just kick me back to the menu. R-Type did this for me as well, so it isn't just CPS2.

Lastly, I wouldn't be concerned if these games didn't play, it's just that they are listed as working in the compatibility list, so I know I must just be doing something wrong.

yes, you have, but who knows what :) my only advice is to avoid rebuilding and acquire a non-merged set to begin with. as above, the 'mame 2003 reference set' is the one you want. CPS2 and neogeo games work totally fine with that.

AWESOME! Getting reference set now. Thanks!

Oh! I never thought that this can be the solution. With another USB-Cable there is absolutly no problem.
Thank you very much!

Right managed to work out config in retroarch by pressing F1 and using X and Z on the keyboard but it seems my hotkeys defaults have been lost when I press start and select I can no longer exit the emulators? Is there any reason these would disappear when the Xin-Mo has been installed?

Any help or comments would be really helpful!

Thanks in advance!

I had some crazy glitches when playing Mega Man X in raspi1 with lr-pocketsnes. Solved when switched to lr-armsnes. But now I'm suspicious of the ROM.

The problem has resolved itself. Don't know what was happening there.
The only thing I changed was the wifi setup.

If your aim here is to play these games with two controllers but still choose the player you want, try using the 2-player clones.

For example, tmnt2po lets each player choose which turtle they want to be.

@BuZz Thanks for the help. I will Test some new psu and a fresh Image.
Hopefully it works. Will get in touch with News.
It would be annoying, if the rpi is broken..

@Sevik said in ScummVM Game won't launch from RetroPie:

I too have the same problem.
Quite sure it is a permission problem as the log says:
····/opt/retropie/supplementary/runcommand/runcommand.sh: line 827: /home/pi/RetroPie/roms/scummvm/+Start ScummVM.sh: Permission denied

You were right.. It Is a permission issue .
So I took a look at my fstab one more time and edited it.
This is my new command:

UUID=E44B-FC4E /home/pi/RetroPie vfat auto,users,rw,exec,uid=pi,gid=pi 0 0

I don't know if this change is affecting other permission issues, but it seems to work.

I found the command in this RetroPie topic.

@mediamogul said in [Solved] Cannot configure DOSbox and ScummVM:

OK, drop to the command line (f4 key), then type "sudo nano /etc/fstab". After that you can add the line "/dev/sda1 /media/usb0 vfat auto,users,rw,exec,uid=pi,gid=pi 0 0". Then hit "ctrl+o" to save, "Enter" to confirm, "ctrl+x" to exit and finish it off with "sudo reboot". That should do it, but we'll see.

Update...I managed to sort this problem, firstly by selecting ' core provided ' as the aspect ratio option. Then under configuration set the following settings ..

Save configuration on exit ON
Configuration per core OFF
Use per game core option ON
Load overide files automatically OFF
Load remap files automatically ON

Now each game seems to automatically load in its correct aspect ratio.

Thanks for the help.

@tehswiftone said in Single GPIO button:

Add this inside of your controllers config, don't forget to replace button with a proper button ID. This will be similar to exiting an emulator, you will use select + button to use it. So don't worry about it taking up a button on your controller.

input_volume_down_btn = "button"
input_volume_up_btn = "button"

I have mine setup to use Up and Down on the D-pad. Just change the "btn" to "axis".

input_volume_down_axis = "+1"
input_volume_up_axis = "-1"

Thanks!

@Lyle_JP I'll have you give that a try - I've been using Picodrive since RetroPie 2...

See the documentation on the wiki

@seanr8 I'm having the exact same issue. I'm using the Huijia N64 adapter and the Project Venom N64 controller (from Amazon). Did you get anywhere with configuring this correctly and preventing the extra button presses?

Thanks
