@kruuth No - it's not supported by RetroArch.

@metalhead I figured it out. For some reason the N64's volume level was way higher than all the other systems. So when I decreased the volume to 50%, I just couldn't hear the other emulators.

Such a dumb thing I overlooked.

Just had to adjust N64's config file.

Thanks for your help!

@mofomike83 Since you're just starting, get the latest RetroPie image and flash it on the card - https://retropie.org.uk/docs/First-Installation/

@dalves Games that do scrolling (eg. Auto Racing, AD&D) will typically expand the left and top border by one tile, making the active area smaller and appear shifted right. Some games (eg. Space Battle, Shark Shark) that don't scroll, expand the left border anyway, for no good reason. PGA Golf, Deadly Discs, and Sub Hunt are examples of games that don't expand the border and should look centred.

Regarding resolution, maybe it's a good idea if the Retropie creators add a default -z1 switch to the default jzIntv command. That way it looks decent out of the box.

Might also be a good idea to add a default --kbdhackfile switch along with a sample keyboard hack file (empty except for some comments), along with the official jzintv keyboard hackfile documentation with the install of Retropie jzIntv

This is a good place to start

@a12c4 My suggestion was for the situation you described where you have a .cue and an .img, it's clear that the .img functions as a .bin file. Give it a try and see if it works.
For other things, you could get away without a .cue file, but I don't think it will work for the situation you described - .bin containing both data and audio data. A .bin without a .cue means - for me - that there is only a data track on the disc image file, in which case you can rename it to either .iso or .img and don't generate a .cue. If the .bin/.img/.iso contains something else besides 1 data track, then the emulator would not be able to separate or read the separate audio/video/whatever info because it would not know where to look them up.

@xvo I have tried everything from 1080p down to 640 x 480. No shaders on at all. I have not seen them enabled in retroarch at least, nor did i ever enable any.

Look for the .rc file at /opt/retropie/configs/mame-advmame

But be careful. Changing the .rc file is tricky and a can result in a failure to boot into advmame.

@quicksilver I have 6 button setup working on both emulators as of now. I found the settings you mentioned in Mortal Kombat II but changing them made no difference. I went over everything on my setup and was stumped. I booted up a fresh image, completely up to date, configured my SNES and Xbox controllers and put on my Sega games only. I made the changes to the respective config files and presto it works. After changing the setting you pointed out that I missed earlier in Mortal Kombat. I don't know why my original setup was not working. It has to be something I modified but I haven't found it. Thanks for you help and if I track it down I'll let you know.

Update: I think I found the problem. When I updated in the morning I did both binary and source, I've never used source before. It wrecked my controller configurations. It had my generic SNES listed as generic and just SNES, and the Xbox controllers were listed as generic Xbox, the original config, and Xbox 360 Pro. Every game I launched listed the two controllers I had connected twice and then worked in piece. Not sure why updating from source would do this as I have updated from binary and it was fine. In the future I will probably unplug all controllers and use the keyboard for updating.

@retronoobie3000 I know this does not help DosBox but malcolm's Revenge runs flawlessly in scummvm.

@mike001 issue is resolved don't know why but I repeatedly paired and it finally showed up.

@spider910 For my project, I simply made my own using Cat5 wiring. This allowed me to cut an exact length, kept everything nicely bundled inside the insulation, and made it very easy to know which wire was going where as opposed to everything black which would be a bit of a visual nightmare. I simply crimped on my own spade-type connectors to mate with the microswitches (most arcade parts sellers sell these in bulk, or easily found at hardware stores). The encoder end for me uses screw terminals (IPAC) so this was ideal, but I could have added header connectors too.

I don’t have any experience with this particular setup. But do you need to be root user to make these changes? Being logged in as root has changed permissions in the past for me that broke my setup pretty bad.

Maybe you can run the utilities with sudo as user Pi and see if that changes the outcome. I may be way off base. I’d love to see the results of this on a CRT when finished. Good luck

@bogus You can save the relevant part from the configs for the overlay part, they should be easy to re-apply - https://retropie.org.uk/docs/Configuration-Editor/#advanced-configuration

@robmcc83 Only if it's supported by the emulator - but it doesn't seem so.
There is a libretro core for Vice (C64 emulator - port of VICE for libretro) in the experimental packages section, you could try and install it.
