@skrapps You can, through the Emulationstation menu, set the game ratio, and it is even possible to set this setting per emulator if you want.
Another option is to activate the Perfect Pixel function, which will make the recalbox keep the original aspect ratio of the screen at all times.
Make sure there is no specific zoom option enabled on your TV/Monitor as this could be the problem.
@zing You´re a genious!! I edit (previous backup) the es_input.cfg in \SHARE\system.emulationstation folder, change the default value of A for B value and also changed the Hotkey value for the default one, rebooted and voilá!! I have now set my buttons like i have in my old recalbox 4.0 and all of them work perfectly.
This is the config that worked for me, in case someone has the same issue:
@zing Thank you very much. I've seen this tutorial before, it doesn't address my problem. But you helped me anyway: I once again went to the command-line, and I asked myself: where am I actually? So, out of nowhere, I just typed:
Then cd .. again, and now I'm finally where I wanted to be all along. It was just unfamiliar to me: In Debian, being root and typing cd (without the two dots), brings me to the very "root" in Debian (shortcut). But in Recalbox it doesn't. It's probably due to the different partition, I'm not used to that. So: problem solved, much learned! Now I can finally access the share partition/folder how I wanted to.
A simple user cannot install anything, as it goes against the original idea of the Recalbox project, which is to be as ready-to-play as possible. Really Retropie is a system whose idea is that users install everything they want, the principle is practically the opposite of Recalbox (though obviously both are focused on retroemulation), and automatically to be this way, Retropie "forces" the user to install and configure everything from basic to advanced (and it's one of the reasons I prefer Recalbox).
Unfortunately, as I'm not a developer (I'm a "simple" user) I don't have enough technical knowledge to support you on how to build your own Recalbox build, and that's not the kind of support we give on the forum either, but the instructions are at the link above, in case you're interested.
Probably from video mode, if not I have no idea what it might be, you need to test all the possibilities of video mode before you can guarantee that it isn't.
Is recolbox-user-config.txt the correct configuration file?
Yes it's one of the options, as long as you've edited it correctly it should work, how exactly did you edit it?
what settings have you edited/added? It's hard for me to give an opinion without knowing what you've done. It's a common mistake for users not to remove the # sign in front of lines (if it doesn't, it doesn't work), or edit with the wrong parameter, or not restart and think the change is immediate, for example...
But if you edit the videomode in recalbox.conf, it usually solves the problem, have you checked that?
@pimpyjoe I recommend that you only make subfolders after you get it working.
Sorry, I don't think I was clear on the question: do any MAME 2015 ROMs work?
You mentioned .chd files, these are special files and these ROMS are more heavy, please test with some more "simple" ROMS without .chd files.
Have you checked your BIOS?
You have downloaded a ROMS package, but you have updated your gamelist yourself, or are you using a gamelist that came with it (imagine that there is a possibility to set the core by ROM if this is configured in the gamelist, even if you set the core to the emulator, the specific ROM configuration is what is considered).
You are not able to run Recalbox directly from the SSD because you are doing it wrong:
Rpi is not designed to boot the system other than from the SD card. You need to install Recalbox on your SD card, and use your SSD to store the ROMS/BIOS/saves/etc, just select the storage location from the Emulationstation menu.
