It was me that was blind... I found it... =)

It all has to align with the ROMs and BIOS being compatible in the NeoGeo or Arcade ROMs folder. I cannot link you to any files that I am certain are compatible but do some searching and forum hunting at some emulation sites. I been having good experience with the latest NeoGeo game files and BIOS. No need to go back to older stuff IMO.

I fired up other games on lr-FBA-next last night and the overclock I did for Metal Slug was saved for the core across all games. Not sure how this affects anything if it's worth just leaving alone.

NM...apparently I didn't look close enough while poking around in the setup script. :-\

@mattw24 It seems that you have no hotkeys to savestate, and this is why it is not working.
Try it without the trailing 2> /dev/null (this let us see the error messages, if they exist). Just:

grep -R save_state_btn /opt/retropie/configs/all

I suggest you to reconfigure your joystick in emulationstation: press Start and select CONFIGURE INPUT.

I'm sure your problem is very simple to solve, and I'm sure that if you read and understand the links above, you'll solve it easily.

Thanks for all the help @Floob. I noticed while setting up a second controller that emulation station seems to reasign A and B any time you set up a new controller and go in and out of an emulator. Is this a bug if so I would think it needs to be fixed not to cause anymore confusion. Seems to only happen with these controllers. I fixed it by manually updating es_input.cfg but I had to do it twice because of this.

ohhh baby! that 4.0 is awesome.. a lot cleaner interface than that of the 3.x version.

I found a different rom that works perfect.

@Kristopherson05 said in Famicom Disk System ( FDS ) and lr-FCEUMM:

Excuse me but when I try to play famicom disk system games in general it boots me back to the main menu. Im no tech wiz so I have no idea what to do. Do I have to do something with the BIOs to run .fds games?

You need the file disksys.rom and it needs to be in the bios folder. Fceumm cuts off video on the left and right side of the screen. Nestopia does not. I personally would use nestopia. Same with nes games. (Unless you are using retroachievements for nes games which only works in fceumm. Fds games dont support retroachievements so i would use nestopia)

For others who have this issue, I figured it out.
The config file for individual emulators is in home/pi/.config/retroarch/config
deleted the config file and all is working fine.

LOL yes nice to meet you too.

Ok - see how you go. Post back if you need more info.

@herb_fargus I'll think I start with a fresh image again, I don't recognize a thing. Suddenly anti-aliasing is on (should never have been invented) and emulators don't recognize hot key combinations.

.7z is a compressed format, you need to open that and take out the compressed file.

@alexis-puska that was @meleu that provided the workaround.

@Concat

That is a killer little display case.

As for the case I'm using, it was a combo case with fan I found on ebay for a couple dollars. It doesn't look the best now that it's in my hands, but it beats having the board laying on the table.

For any Mac users who happen upon this later through a search, ApplePi Baker is a popular and completely free alternative.

@caver01
I will have to double check when I get home, but I am pretty sure it is Mame4all-pi, but I will confirm.

I configured the buttons holding them down on launch yes. Same for Emulation Station. it shows as Generic USB Joypad Controller when I set it up in Emulation Station by holding the buttons down.

That is how I was trying to fix it. I used Tab on they keyboard and went to PLayer 1 Start and Coin. I pressed Enter and then pressed the button I want it to be. It then accepts that button and says J1 Button 5 or whatever it is (again just trying to remember)

I will try going in and resetting it to defaults and trying again.

I had to move everything from one build to another as I didn't like the design, but I had the same problem on the first build. All buttons were left the same. I will try that, and also look into the retroarch.cfg file and see.

I am 99.9% sure that I don't have the same button set elsewhere but I will double check again and get back to you.

I appreciate it.
