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.

Was able to map xboxdrv, but cant get it work correctly. Guess I will just use a PC.

@Atomize It's impossible to assist without the information requested in:

@RedBatman you should read this post: https://retropie.org.uk/forum/topic/2859/how-to-use-mame-with-retropie-help-guide

And, of course, the official docs too: https://retropie.org.uk/docs/Arcade/

Thank you. Trying to find that as soon as I do, I will get it. Sorry. After a bunch of tries its hard to be optimistic....

Well for the GBC all you need to do is to drag n drop the roms into the rom folder of GBC.

As for MAME. Well, you need to know which emulator you're going to use and you need that romset, lets say the romset is something like the version of the roms.

I can recommend you to use the lr-fbalpha emulator, this requires the 0.175 romset. if you can find this romset and download the games you're fine, all you have to do then is drag n drop the mame roms to the FBA roms folder and you're ready.

However, if you find a different romset you need to "upgrade" this romset to the romset the emulator is supporting. You can do this with a program named clrmamepro.

Here is how I did it the quickest way, just check this page:

https://github.com/retropie/retropie-setup/wiki/Managing-ROMs

See which romset is needed for the emulator you're going to use, like for an example "fba 0.2.97.39" Just add the two magic words one starts with a "D" and the second starts with a "R". Use Google for this. There is one site it's name starts with an "A" and ends on ".org". Well I said to much now... Good luck!

@PetroRie said in I can't get MAME to work:

Also I would like to say if you manage to get it work, dont update the mame emulator anymore. Because if you do you will need a newer romset so you need to convert them etc. Can be a pain in the butt.

only lr-fbalpha core keeps parity with current FBA romset. you can safely update the rest without worrying about your romset :)

@colourgraphics said in Player 2 not working - Using arcade controls:

input_player2_a = "s"
input_player2_b = "a"
input_player2_y = "q"
input_player2_x = "k"
input_player2_start = "num2"
input_player2_select = "num6"
input_player2_l = null
input_player2_r = null
input_player2_left = "d"
input_player2_right = "g"
input_player2_up = "r"
input_player2_down = "f"

I've tried doing exactly this, and cannot get Player 2 to work in Arcade for the life of me. It works great in NES, SNES, etc... but doesn't work at all in Arcade. Any tips/advice?

I have a problem where I deleted it but it wont recreate the file? any ideas or help with that.. I have chmod the cfg directory to 777

mame4all works fine

lr-mame4all wont work at all
