Ok update as I seem to have managed to get this working. The key for me was to follow all the instructions from @SuperFromND at the top of this post.

Once complete, when i tried to load the game i got "No config found for system mugen" and I was sent back to emulation station.

I eventually ended up editing my etc/emulationstation/es_systems.cfg file as per the below

Replace

<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS mugen %ROM%</command>

with

<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 PORT mugen %ROM%</command>

Restart emulation station and to my amazement - it worked!

@profiteer

What is your sha1sum of the hotmario.chd ?
I managed to softload without changing the sha1 in the hash.
Although working it's indeed a bit of a hassle to get it working.
Found from the runcommand.log that the chd searches a specific name in a specific folder.
If you want a clean roms/cdimono1 roms folder with only hotmario.chd then that file need to be a link of :
/home/pi/RetroPie/BIOS/mame/cdi/hotmario/hotel mario (1994)(philips)(eu).chd
or (not ideal but will work technically)
/home/pi/RetroPie/roms/cdimono1/cdi/hotmario/hotel mario (1994)(philips)(eu).chd

As both paths are added in the runcommand as search paths.

You can also make a dummy file but then the checksum is not correct for scraping gamelists.

Hope you understand this information.

@DTEAM

Super, looking good ;-)

@JimmyDansbo After testing with the official repo i updated the script to point to it and it exits the emulator fine with ALT + F4 so that's perfect. Just need to work out how to squeeze better performance out of the Pi as i only tested a handful of games getting them in game and then closing the emulator.

I would say it's on par so far with the Sega Dreamcast, Sega Saturn which means it can be used but it's certainly not ideal and it also depends on a per game basis. I ran a text based adventure on the Pi and it ran ok and completely usable but one of the space games it was sluggish both in game play and sound and was a little distracting from the enjoyment.

I'm wracking my brain to figure out what could be done to squeeze a little more performance out of i, even if we got 5/10% extra it would be something although ideal if we can get closer to 95-100%. I'll report back when i find a solution or something.

Skyscraper 3.17 just has been released including these highlights

ZX-Spectrum scraping works again Relative paths can be used for the majority of configuration options and command line options Artwork options enhancements ...

Updated the guide a little

Snapshots (game saves) are saved to the xbox hard drive image so just backup your hard drive image if you want to save your games and you access and manage them via settings menu.

The emulator doesn't come with a standard bios, every game has to be decrypted with a key that matches the game and region so the emulator can read the game data. A user will have to source a set of up to date keys which are a key.txt file.

Some arguments below i found

--- Launch options ---
-g Path of game
-f Launch in fullscreen mode
-ud Render output upside-down
--- Extractor tool ---
-e Path to WUD or WUX file for extraction
-p Path of file to extract (for example meta/meta.xml)
-o Output path for extracted file.

Just figuring out the default key.txt location so i can run a game and then work out how to get the keys stored under /BIOS/wiiu and have the emulator automatically see them in the location.

@Protocultor said in Quake 2, 3D accelerated in any Pi model, 60+ FPS:

Does somebody know when the binaries are updated after a PR acceptance?

There's no rule or schedule, but we can ask @BuZz to update them. Currently the binary is still installing the 8.41 version.

@dewiele said in Game and Watch ‘Game B’ button mapping:

I tried MAME standalone originally and got the game and watch ROMs running however by default the TAB menu was inaccessible as the PSPi controller mappings were not set up.

You should use a keyboard first.
I you somehow use the standard runcommand :
mame = "/opt/retropie/emulators/mame/mame %BASENAME%"
and it still doesn't work with the keyboard then you could try to add "-ui_active" to the runcommand.

Some update about this twin-stick feature, it has been added to Forgotten World (CPS1) last year and to Eco Fighters (CPS2) yesterday. Now every rotary games in FBNeo should have this support.

Special thanks to pjft and dink for their work on this.

Anyone willing to share a link with their file with pastebin.com?

After more than two years, I finally found the motivation to work on this project again and improve it.

New features

The biggest new feature is the ability to check a romset against a DAT file, and to transform a romset into a non-merged one. Several common DAT files are provided: MAME for the latest Batocera and Recalbox versions, MAME2003 in different flavors, and FBNeo. Merged and split sets are not supported, as they make no sense in the context of this tool.

Other new features:

Completely rewrote the "top x" lists in the wizard and added some new selections Added some new games lists in the wizard (4 buttons, vertical, multiplayer vs/coop) Before copying files listed in a CSV, the app now lists the missing ones Added the possibility to help translate using Weblate New translation in Swedish - please contribute to other languages if you can, it's not hard! A new console application has been created, in case you want to automate things In the latest MAME versions some files (other than samples and bioses) are needed, they are now copied along with the roms Fixed bugs The Windows zip file version launches the debug window upon starting Crash when a CHD file already exists 404 link in the help section Encoding error in some JS error messages Path with "+" doesn't work

I just tried with my fork on a Rpi5 to create a Rpi3 image.

The warnings in creating the chroot image (your step 5) can be ignored.
xpad and usbmount fail with an error but these can be re-installed on the real Pi3 if needed.

When the final image creation (your step 6) fails with something like

device-mapper: reload ioctl on loop0p2 (254:1) failed: Invalid argument create/reload failed on loop0p2

just run it again.

@Chef-Otis, have you followed the steps in the README? Were you able to start the service, or what issue are you facing exactly?

I usually respond faster when the error is reported through this channel: GitHub Issues.

@boxwine-exp

I mean about this script

@mitu Awesome! Thanks.

@mitu i'm going to try it! maybe I need to adapt the flags on my system and it will work!
