@davidc100 Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

@benjiman You can use the File Manager - in the RetroPie system menu - to look in the file directly on the Pi, but it's easier if you have a PC and connect via file shares at \\retropie\configs\all\emulators.cfg.

You have two options: Stick with official plug and play devices like (s)nes classic mini Start a new hobby creating your own personalized Retropie system by starting from scratch. It's not that hard. All the information is readily available on this website. You may want to invest in a quality micro sd card first.

I forgot to mention that before scraping all roms worked fine.

@luisv96 said in Certain roms dont work on lr-genesis-plus-gx: @mitu when i try to run verbose logging nothing happens What do you mean "nothing happens"? Did you check the log in/dev/shm/runcommand.log ?

@saint_jimmy Happy to help! No, just follow the instructions and from then on you can just plug your usb flash drive in your pc and transfer your games to the usb. Save files will be stored there as well.

After much hair pulling and searching, I managed to find the solution to my issue. All of my ROMs except for Gunstar Heroes was a 0kb file. Once I replaced the empty files with good ones, they all played perfectly.

How much free space is there on the sd card? In emulationstation, press F4 then post the values below Size, Used, Avail here.

@zaphod42 For PSX games you have to have them extracted because the emulator reads .pbp, .iso, and .bin/.cue so if you want to play your games you have to extract the files.

@mediamogul said in some MAME ROMs do not fully load using lr-mame2010 emulator: 0.139 MAME ROM @mediamogul I was not sure, so I deleted this ROM and downloaded a new one for the same game from this set. And it works!!!! Thank you!

Update on this. I was able to get this to work with previous images, and the ones I made off my disc. I had to wipe my SD card and completely re install Retropie 4.2 from scratch. I am not exactly sure, but maybe something did not update properly when I updated from a previous build.

@Adam_3D Try launching a game and then post the contents of /dev/shm/runcommand.log.

@DamnAlex Glad to hear it.

@dansharpy said in Completely lost- noob warning!: ok so ive just downloaded a different rom and put it in its relevant folder so think it may have been a problem with the rom download. Thanks for your help anyway! What was the extension of the rom file you uploaded to your Pi? Open it and see if there are more files in it.

nice! have fun :) for some reason tekken 3 used to crash after the ending cut-scenes in arcade mode, but other than that it worked ok. Don't see a way to delete this thread otherwise I would.... we don't delete threads here :) technically this should have been in help & support, asked as a question, and now marked as solved. i've done that :)

@pjazzy11 said in MAME4ALL Not running Some Roms: The arcade emulators i have are Arcade,FBA, MAME-Libretro and Mame4All. Arcade is not an emulator, it's a folder. You have to read the guides or you will become very frustrated over time, especially with MAME. https://github.com/retropie/retropie-setup/wiki/MAME#arcade-rom-paths

Good to know that it just works and you can enjoy it ;)

Reboot emulation station? Also the path for .gb games is /retropie/rom/gb
