@mitu

Wow! At some point I did disable the save on exit setting. Thank you.

@kounabi22 Oh dios mio es este! OMG! is this! Thank you so much!

@chuck_g said in Which folder should I add my MAME roms to?:

And advice on the ColecoVision Em?

Install the emulators for ColecoVision ? See https://retropie.org.uk/docs/Colecovision/.

I am using redump.org site, to validate, that my roms are the good one. But it doesn't have all the systems.

@tmoe01 said in Issue launching ROMs:

... then goes black again before returning to Retropie.

Using the desktop is not supported on Raspbian/Raspberry Pi, start EmulationStation at boot (from the terminal) and not from a desktop session. More details how to configure that here.

Thank you guys for all the assistance. I have NO idea what step created those huge .cfg files. I'll have to keep an eye out for that.

You used 'Save Configuration' in RetroArch's RGUI. Either that or you enabled 'Save Configuration on Exit' from the RGUI.

That is ABSOLUTELY it. I've been trying to figure out (without luck) through trial and ERROR, how to get to where I can cut off the initial post period of some of the roms (like Defender) and auto-load the "clean" state as I used to do on my PC version of MAME.

Wow. Glad to have a solution and a reason.

@barbudreadmon @mahoneyt944 Sage advice from both. Thank you again for taking the time to help!

@dankcushions
I did see that set. It's on my list of things to get.
I see in my future getting a merged set of ROMs to save download time and creating my own non-merged set afterwards.

Do you think my 9 year old PC might be powerful enough to run most games on the latest MAME? I know it is leaps and bounds ahead of the Pi, but I don't know how PC processing power compares to arcade hardware.

EDIT: Forgot the age of my PC

You would put what you want scraped in the 'Games/Roms file extensions' line. I have chd,m3u. I do not use bin or iso.!

@kmancali , on top of what @mitu said, if you want to have some systems directories in different mount points (or partitions) symlink just those directories:

/mnt/roms/amiga to $HOME/RetroPie/roms/amiga

while $HOME/RetroPie/roms remains in the main partition

@alphabetapie most of the dat files for the supported MAME emulators in retropie are available in the docs: https://retropie.org.uk/docs/MAME/

so from there you can see how many versions of a given game there are. on latest mame i can see 2 versions of vcop and vcopa (revision A). these don't seem to be language designations.

doing some research: http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=vcop

0.155: Changed 'Virtua Cop (Revision A)' from a parent set to clone.

so it might be that rev a was the japanese version and from 0.155 the parent is USA language, or it could be a system menu thing. but without logs or any kind of diagnostic info we're just guessing.

@jimiretro Usually you get a message only on errors.
If the mount command worked, then check if the roms folder is populated, then start EmulatonStation.

@jorgejohnson72 You can exit EmulationStation (from the Quit menu) and run, from the command line:

Go back to EmulationStation by typing emulationstation.

Thanks @thorr69

I found deleting the RTB files in:
retropie/configs/amiga/amiberry/whdboot/save-data/Kickstarts/

Then restarting sorted out the issues I was having. I think there were some leftovers from the other files causing a conflict perhaps. Sorted now though.

@leon21
You can find old versions of Retropie here - https://github.com/RetroPie/RetroPie-Setup/releases

To be honest, I would try a different version of the rom and see if that works rather than downgrading Retropie.

@mitu thank you for thee replay it really help so much thank you again
