MAME ROW #167 is now live!

@cyclair Probably not enough. The link clearly asks for some logs and config files so that we aren't pulling things out of thin air. To be clear, with pretty much thousands of people running and playing vertical games on the official image, especially on the RPi3B that's been around for quite a while, I would vouch for the fact that what you're facing is pretty much configuration issues from that exact image.

But do share more details per the link shared above - type of screen you're using, etc.

Thanks very much for the detailed reply, it seems like the benefits will outweigh the pretty minimal cost.

@dankcushions no I wouldn’t ask you to and thank you it’s really helping me and I promise no more questions (for tonight at least)

This is the only "beat 'em up" I put on my cocktail cabinet. I use a split-screen shader for simultaneous two-player. It's different from what I'm used to (being a non-Capcom-beat-em-up), but I like it. Thanks MAME RoW for re-introducing me!

I did a similar project not too long a go. E.g. built RetroPie into Atari 2600 case. Anyways - yes, key presses that ControlBlock sends when using MAME layout are hardcoded into it's driver:

URL: https://github.com/petrockblog/ControlBlockService2/blob/master/src/controlblock/gamepads/MAMEGamepad.cpp#L41-L141

To change e.g. switch 'z' to send something else than z, say a, you would modify lines below and replace KEY_Z with KEY_A. And recompile and re-install the driver (instructions here https://github.com/petrockblog/ControlBlockService2).

URL: https://github.com/petrockblog/ControlBlockService2/blob/master/src/controlblock/gamepads/MAMEGamepad.cpp#L68-L70 to

Available KEY_* events (that you could replace KEY_Z above) are found from here: https://github.com/petrockblog/ControlBlockService2/blob/master/src/controlblock/uinput/UInputEventCodes.h

I hope this helps you forward. I did a slight re-write for the driver myself as I wanted all the Atari 2600 switches to provide their original functionality. Which isn't straightforward since official ControlBlock driver doesn't support switch where both on and off indicate certain state (e.g. on -> colorTV, off B&W). I suppose I could clean up my code a bit and put it up to github sometime.

@arcadez2003 Thats great. So do I just need to get the latest Mame 2003+ core for this?

@zerojay said in M.A.M.E. 0.61 SDL [DEV] - Beta3.3:

From a packaging/scriptmodule perspective, this doesn't change anything for me, but that's really cool.

The current SDL Image library available on Raspbian is an old version that use an old libpng version with a bug. In order to use HD artwork you need to compile libpng and SDL Image from source and in sequence.

So, download these archives, libpng-libpng16.zip and SDL2_image-2.0.5.zip, and copy them in

/home/pi

then run these commands from terminal:

LIBPNG

unzip libpng-libpng16.zip cd libpng-libpng16/ ./configure make sudo make install sudo ldconfig

SDL IMAGE

unzip SDL2_image-2.0.5.zip cd SDL2_image-2.0.5/ mkdir build cd build ../configure make -j3 sudo make install sudo ldconfig

Many 3D arcade titles still struggle on the pi 4. Unfortunately I think we are stuck using the ports for virtua racing. The saturn port is closest to the arcade version and runs pretty good using lr-yabasanshiro. You can get the experimental script module for it here: https://github.com/RetroPie/RetroPie-Setup/pull/3132 (it is not officially a part of retropie yet but you can test it out like I have been).

Unless it doubles as a handwarmer, you don't got a Pi4 in there...

An easy way to replace the artwork location in the gamelist.xml with another / new one is the sed command (stream editor). This example changes the video directory from the relative path ./media/videos/ to the absolute path /mnt/artwork/videos/:

cp gamelist.xml gamelist.xml.backup # make a backup in case something goes wrong sed -i 's#<video>./media/#<video>/mnt/artwork/#g' gamelist.xml

The part in single quotes does the actual sed-magic:
s(earch)#[old string]#[new string]#g(lobally, i.e. all occurences)

This works for every other path, just change <video> to <image>, <marquee> etc. Omitting the artwork tag before the path will change any occurence in the file, e.g. if the whole artwork is located in another place.

Execute man sed in the command line to get the manpage (manual page) of this tool, or search the web for myriads of examples.

@jmbooth2000 yeah, i was just trying to make sure he had the pi4 issue before posting that same thing.

Tate mode doesn't auto-rotate. TATE mode adjusts the screen to fill your monitor. What you need to do is is specify the exact rotation you want for each game you need to and make a game-specific config file for it. If you have auto-rotation on and auto-rotate on, you will get some weird results. Auto-rotation should be turned off when using TATE mode (setting allow_video_rotate = false). Some games will need 180 degree rotation. You'll have to decide which end of your monitor you will consider your base (the one that will be the bottom edge when you spin it).

For each game you want to have in cocktail mode, you will likely need a cfg file with the setting
video_rotation = 2
for games that need to be flipped. Set it to 0 (or don't write a cfg) for games that sit the right way from the get go.

This post was greatly helpful for me when I was doing my cocktail setup: https://retropie.org.uk/forum/post/39024

MAME ROW #164 is now live!

@colstar since that's not the version of any of our recommended arcade emulators in my previous link (or indeed any of the supported arcade emulators in retropie at all), i would forget it and acquire the set for one of them instead.

@barbudreadmon Cool, that’s what I needed. I started my RetroPie project years ago but haven’t managed to get the arcade games the way I wanted until now :)

@sirhenrythe5th said in Which Mame is suggested for the a Pi 4 with 4GB of Ram?:

@Jiryn But you got it working now?
Hint: if you map "Cancel GUI" to "select" + "start" you can exit the games like you are used to with the lr-emulators ;)
Hint2: if you furthermore want to get rid of the exit-menu, set "safe_exit=0" in the AdvanceMame-config-file.

Sadly no, when I hit tab and try to configure my controller it just ignores it
I've tried both general and this game and neither seems to accept the inputs of the controller

Unless I am missing something
Games run great though!

Nm fixed it!
I have to hold the buttons to register...I can be a derp
How do I save it though? When I switch or reset all my controls disappeared

You will run into issues later on with this approach. You need to match the specific ROM set version to the arcade emulator you want to use. This is detailed in depth in the docs.

@grant2258 said in Dragonrise joystick to MAME Emulator:

@Shazam make sure all your controllers are wired the same as far as buttons go this is a common mistake that some people do.

Let me explain whats going on here say you has an xbox controller in and set it up then plugged another in it would use the same mapping as you set as the first one because it saves the setup for that controller type(retroarch).

The same thing happens with the dragon rise its regarded as one controller type you need to wire them up the same so they all match and you only need to set one up for them all to work. I can guide you guys on mame2003 or 2003-plus to get started if that would help.

Hi Grant - I would love some help please! see my post here.... https://retropie.org.uk/forum/topic/26386/dragonrise-usb-issues
