I FIGURED IT OUT :)

I just had to do some special config in the tetrarch controller settings and then make sure to save that config file so it would be persistent after reboot. It is working now.

I recommend to read the RetroPie Doc's about arcade emulation: https://retropie.org.uk/docs/Arcade/

Of course, we can't provide links about bios or roms files because is illegal and against of RetroPie community rules.

@anthonyamar The Retropie Project frowns upon people trying to profit utilizing their software. I'm sure other people here will fill you in.

@BKCoder WOW. I love this.

Any details that you are willing to post would be great. Either about Software setup, physical hardware, or design ideas.

Thanks for the post.

@Rhys said in Using Chromium as an "emulator" for Scratch projects:

Does anyone know if there is a way to temporarily enable and disable the GL drivers from the shell, on the fly, without having to do a reboot?

No, unfortunately this is cannot be done on the fly - it needs a reboot and thus would 'break' RetroPie's front-end (EmulationStation).

Excellent!

@common763 Why can't you control things with the arcade controls? Also, are you in a standalone version of MAME?

@ryan said in Hello New here please help:

I am making an arcade with a IPAC2. How can I set up a two-player system once I'm on retropie? Thanks.

@red732 a shader could do this. eg: https://github.com/libretro/glsl-shaders/blob/master/misc/flip-horizontal.glsl

any arcade game that was available in such a cabinet probably has a system option to run it in a flipped mode - maybe in the service menu or dip switches. eg https://retropie.org.uk/docs/lr-mame2003/#service-menu

I’ve just registered to say I love this! I’m currently building my long awaited man cave and would love one of these in it!!

I’m a complete beginner when it comes to raspberry pi etc but am pretty handy with the mechanics/electrical side of things.

An I ask what games you have?

Many thanks!

@Clyde said in Finally Finished:

Nicely done! And a refreshingly different design.

Seriously, I love all the super clean and modern builds that people do but this is so cool. It looks like it should be in an awesomely decked out barn converted for hanging out.

@ReadyPlayaWon
Not "really finished", just need to to put a piece of MDF on the hole

I used these guides to decide my layout, started simple but managed to squeeze a mouse based trackball in the middle after moving things around. Still doesn't look cluttered

Standard six button layout, plus two extra per player for 'shoulder' buttons ZL/ZR so I don't also have joypads laying around so ended up with 8 buttons per player that wasn't my original plan

https://retropie.org.uk/forum/topic/5220/arcade-buttons-how-many-layout

This was my original layout, but as I also wanted true pinball emulation (the PI simply can't handle anything like Future Pinball or Visual Pinball) I also added two buttons on the cabinet sides for pinball flipper and also load/save states for emulators that support it

Hence finally going down the IPac4 route. Worth the extra effort as its a true keyboard interface that supports multiple buttons and upto 4 players or in my bartop with lots of buttons and two players. BIG improvement over the Chinese USB interface that the kit I bought came with

This is basically the joystick/button set I used, but had to rewire the joysticks to fit the I-Pac interface. Not difficult

Speakers were taken from a dead 2.1 PC speaker set and bought a cheap 2.1 amplifier that runs off 12v from China. Its rubbish and needs changing for a better quality 2.1 amplifier but it was a start

I'll post a picture of my bartop later today sometime. The vinyls and edging need adding but this is the case I used for my PI bartop, I just squeezed a PC motherboard and power supply inside when I decided I wanted pinball emulation and more intensive emulation the PI will never be able to manage such as PS2/Wii/Wii U/Xbox

This is the original layout I used, but added a trackball mouse. The PI can easily support USB hubs but make sure its a powered one and one that doesn't reverse power. A lot of cheaper ones do so send power back to the PI, Buying one from the PI HUT will guarantee it works as it should

This is the trackball I used, but for the PI you will need a PS2 to USB adaptor. It works exactly as it should so I can also play trackball games as they should be played such as Centipede and also it functions perfectly well as a mouse, but I had to add yet two more buttons to my cabinet panel to use it as a mouse when needed. Amiga games need a mouse and this works perfectly for them such as Cannon Fodder. Amiga emulation will be no problems with a PI4 as it worked on a Pi3B easily

Also found a few things you might find interesting. The passive aluminium heatsink case for the PI4 looks interesting. I would consider adding a standard PC case fan on top as the guide says the casing WILL get hot and make it run even cooler with an extra fan. Should easily power the fan off the PI itself

Son of a birch, that is a good looking cabinet!!! Love me some woodgrain, so this is glorious all around.

Bah! Alright, I'll go that route.
Hey, thanks for your help, @mitu. I really appreciate your taking the time!
