@mitu FANTASTIC !!!!
Everythings working with lr-fmsx!!! I focused to much on Lr-BlueMSX. For Lr-BlueMSX, It's only playable with keyboard . The joypad working only for Coleco. Not enough gamepad buttons are associated with basics keyboard fonctions. They should enable the "RetroPad Keyboard Map - Joypad - Awaiting description" option in Control menu in RetroArch for MSX.
Thank you

@akamming said in RetroPie setup reverting cmake to 3.13:

i noticed however that when i run the Update command from the RetroPie setup script, cmake is reverted to 3.13 again. Apparently it does not detect that a higher version is already installed, cause i also noticed that cmake and cmake-data are installed again as raspbian packages.

It does not detect it, because it's not installed from a .deb package. RetroPie installs the cmake package that's available in the distro - whatever version is available in the Raspbian repositories.

As a general rule when installing from source - in order to not get your installation overwritten by a distro package, don't install into the system directories (/usr/bin, /usr/sbin, etc.) - use /usr/local or /opt.

@mint OK My fault. It runs OK with another different disk image.

@nightbirdmedia mupen64plus-gliden64 isn't a libretro emulator so you can't use the retroarch menu. The save states are not compatible but there are conversion tools out there if you have existing save files. The default save file location for standalone mupen64plus is a little weird but you can change it by editing your mupen64plus.cfg and pointing it to save to the rom folder.

@Tango said in usb trackball & spinner mouse index issue:

When is the include needed and not needed? (They use it in some examples in the link you provide, but not in others.)

It's not needed in a ROM config file.

Thanks!

It worked! Unbelievable. That is absolutely amazing. Thank you, @mitu !

Set-up the PI with the USB device, then configure the Mint install to also mount the same USB device, but using the Manual method.

When scraping, you'll have to use an external scraper and configure it to save the artwork in the ROM's folder (EmulationStation saves it in $HOME/.emulationstation by default, which is not on the USB drive).
EmulationStation themes will not be transferrable this way, you need to install them on both machines.

It looks like your installation is quite old and I'd say updating will not work, (Unsupported OS), and the current version does not support your - very old - Raspbian version.

If you'd like to use a current version, then use the image from retropie.org.uk/download and re-image your sdcard. You can back-up your ROMs via file shares - https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup-option-2.

Without seeing a log file - /dev/shm/runcommand.log - or the actual configuration file, it's difficult to say what is wrong. The default configuration file installed by RetroPie should always work (retroarch.cfg.rp-dist).

Also, please add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@xgamer020 Please open a separate topic and describe your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
If you experience the same symptoms as in the current topic, then I'm afraid that the advice would be similar - backup and re-image.

@mitu ok great! Glad I wasn’t messing something up

@mitu Thanks sorry you are absolutely on the right track I was editing the wrong file.

@mitu Thank you for all your help, it seems to be working now!

For ChannelF libretro core

Working well for me, except on my pocket console (don't like teensyduino with START button)

@jpm92 Nice! Thanks JPM!

wow this has been covered extensively here..but I know it is always a pain in the tail...

Using the genesis gx plus core..(the pico core WILL NOT work) make sure all your controllers are plugged in and are configured first!

Start the game... once game is loaded go the the retroarch menu by pressing select+X). in the QUICK MENU go to the controls menu. for player 2 (Port 2) set it to MD 6 button + 4-Way play (Teamplayer will work here oddly enough) and then back out. on the controller main menu select "Save game remap file". quit retroarch. reload the game..then test it (with friends of course!)

Problem is there are two type of multi-taps for the Mega Drive/Genesis. One for sports games made by EA sports (called Teamplayer)and another made for "general four player (non sports) games". Normally that means the 4-way play. It is hit and miss on the game..some wanted it in player two..some wanted it in player one. But it works for this game at least just like I typed above.

Happy gaming! :D

@dankcushions it's a fresh setup so ssh is off. I'll look later to see if I can enable it.
Yea, soldered to the board. Maybe I damaged a component too.
UPDATE: I was cleaning the solder joints of the reset pins today. I also noticed I was testing from the 2nd hdmi port so that wasn't giving me a proper display. Maybe the rescue image did do its job. Seems to be working now on 1st hdmi port.
