I have updated retropie through the menu, but still having the same issues.

5v - 2.5,its the one that came with my retropie kit when I bought it.

No, I haven't touched those files. At least not that I'm aware of.

@Dta316 I have not come across that issue with the Ipac2.

Ok update for everyone, I made a last ditch attempt by using FileZilla and it worked straight away. Not too sure why Finder and Cyberduck couldn't work but all good now. Thanks.

@dudleydes yeah i got it working. I had to chown the /home/pi/roms folder back to pi owner and from there i got wolfenstein full version working great. I did have to google to learn about the lowercase. Now my next thing when i wake up will be to work on hexen series and chex quest.

I use several of these zero delay boards. It should just work. Plug it into a PC and see if it works there. If it does not show up on the pc, it may be defective.

Turns out that there is an issue with the DIY install for the latest versions of the Raspbian and Ada fruit are looking into it.

I'll have to get by on the older version they have in the pre-made Wheezy image for the time being.

@Hydro Do not use explanation points. No one here is on your payroll. I am done trying to help you.

@aland93 glad to help.

I can't see any problem in the screenshot. The error message can be ignored. It has recreated the second partition at full size by the looks of things.

what is the output of

sudo blockdev --getsize64 /dev/mmcblk0 sudo parted /dev/mmcblk0 unit b print df -h

@thrussmeister if you open up /etc/emulationstation/es_systems.cfg you can move the systems into whatever order you like. I have mine arranged by: whatever system i modded a pi in and all that manufacturers consoles, then oldest to newest but keeping manufactures system altogether. Consoles first, then arcades, then computers.

You're really going to need a rom from one of the listed rom sets that correlates to one of the already available arcade emulators in RetroPie. So, if you wanted the latest non-experimental Mame version of 'Cherry Master' for RetroPie, it would need to be from the 0.139 Mame rom set and you would launch that rom with lr-mame2003.

Edit: Being a Neo Geo game, you will also need the neogeo.zip BIOS file from the 0.139 Mame rom set as well.

Edit 2: Of course this example is just for Mame. Many people prefer running Neo Geo games through the FBA emulator. It's just important to remember to match the rom set version to the emulator you choose as detailed in the two links above.

Did kof98.zip and neogeo.zip get verified by clrmamepro? Where did you get the .dat file?
How many files are in your neogeo.zip?

Does this output anything if you type once youve tried to load the game?

nano /tmp/runcommand.log

I just tried it and it does work.
Make sure you put your zip files in
/home/pi/RetroPie/roms/mame-mame4all
I selected to run that in lr-mame4all as the default in that dir is mame4all.

I would say either your romsets arent correct, or you are putting them in the wrong rom folder.

This will link the folder roms from your HDD to the ROMs-directory in Retropie. That's a convinient and save way. For future updates you do not have to carry over your ROMS back to SD. Coz you've 2 storages now:

The SD-Card only as Retropie sytem (4GB are enough)
2 An USB-stick for ROMS storage with FAT32 format (easy copy from Windows to the device)

How to link?

cd /home/pi/RetroPie mv roms roms_backup ln -s /media/usb/roms roms

@VFansss i actually use the ps1, ps2 and ps3 pads. I got my ps1 and ps2 controllers in good shape. I wired a hde ps1, ps2 usb adapter soldered to the controller port. I used this video i took off of youtube. You need to rip it to an sd video not hd. (480 but still wide screen and still looks good)

And here is the link to my pi-station 1 i did:

I checked the path in the gamelist, yes all the games are there only in the gamelist they are in the wrong folder.. do you know how I can edit this?

Not even all my neogeo games show up in the list.

@meleu @buzz thanks for your help! much appreciated.

Most of these games are between 30 and 40 years old. Playing them on a HDTV highlights how low-definition/pixelated they truly are. To alleviate that for those who don't like the pixel aesthetic, filters have been created to smooth things out in different ways depending on the filter being used. The smoothing example given above is a popular approach and not very processor intensive, but some people find it too blurry for their tastes.

There are also filters like this that try to take a middle ground by smoothing the pixelation, while sharpening the resulting edge, but some people find this approach too unnatural or plasticy. Something that seems to satisfy purists and revisionists alike is to recreate a CRT look on your LCD monitor like this. Personally, I take the path of least resistance and leave the games in their unfiltered pixelated glory, but at the end of the day, it's all about personal preference. The question you have to ask is, which one of the many compromises is least objectionable to yourself.

@General_Toxic wow! Your post is pretty confusing buddy!
What exactly did you change? What files?
