Thanks @dankcushions I didn't knew that I needed the parent rom. Problem solved. It's up and running. Now I can save my progress in Pacman.

Thank you all.
@mitu and @jonnykesh

You've been a great help.

The problem I had was that I didn't know what the "Insert Coin" mapped to. I discovered (from Google) that it's the SELECT button. Once I knew this, I could edit the retroarch.cfg in the configs/FBA folder and added the following line: input_player1_select = "num5"

Sorted.

Thank you.

PS: I also tried adding input_player2_select = "num6", but it looks like it only accepts P1 setting.

I'm having an issue with sdl1 games in general. Black screen.
So I'm trying the xboxdrv solution. But so far I couldn't make the cursor to move at all when I'm running the xboxdrv. Is there a way to debug this stuff?

@edmaul69 In the end I tried a different game, I hadn't tried others as I'm not a big PC engine fan just wanted to play that particular game, no problem.

So I acquired a copy of the game from a different source, and that's running no issues. Must of been a corrupt file or something.

Thanks for your input @Darksavior @lostless

@mitu
Alright sounds good to me i'll do that then.

Thanks

Did you ever get an answer to this?

@mitu i figured it out- I didnt realize you can still save the traditional way on a pi

Good to go!

@mgrabow It's a compressed .img file.

I apologize for abandoning this thread for so long... you see I had some trouble compiling it on macOS the past month and someone just recently solved the issue for me - there were NO known macOS binaries on the internet for a few months so I couldn't test it locally on my computer

Thank you all for resolving this issue now! Sadly, I can not reproduce this solution on either macOS or Windows... but that is another matter...

@BuZz - so would it be possible to push a new symlink for this into the repo?

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

@herb_fargus
Thanks a lot. Solved

Thanks for your help, mitu.

In the end it proved to be too much of a hassle. I ended up grabbing another SD card, doing a full image install, and adding PIXEL to it. I'll peruse the changes I made to my old OS and do them to the new one.

@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 ?

Well I got it working :-)

I have created a repo on git incase anyone else needs to do this:

https://github.com/bruceiow/rPiVolumeControl

I got it to work.
I used these steps instead:
http://www.pretendo.online/2017/01/25/adding-background-music-to-emulation-station/

Works great! You can easily edit stuff in the bgmusic.py file , like startsong and add missing emulators to mute the sound for.
I stuck my Pi in a Playstation 1 case, so my Pi-station is pretty much done now:

from your screenshot mate, it looks like you're putting all your roms in a compressed zip file. While retropie recognises zip files, they have to be zipped individually with the name of the rom. This is why in your list it just says "add games here" as that is the name of your zip. Take them out of that zip file and then zip them individually and then reboot.

Just did the update... no errors! Thank you again!

@mitu not to mention the latency...
