Thank you following that post did it.

The games you play should support a controller interface, most of them probably work with a keyboard and mouse and not exclusively with a controller.
There are generic gamepad-to-keyboard/mouse mappers, for Linux I know about antimicro, but the best solution is for the game to natively support a gamepad.

@mitu I got it.

To get this sorted... I powered it up and kept swapping the USB cable inputs until it registered correctly in a retroach based emulator (I used Atari2600). Once it set correctly, I checked it in Daphne, JzIntv and DosBox. Seems to be holding and working good.

Go figure... swapping the cables with the power ON did it.

Thanks for all your help again! Pass this info on to anyone that has a similar problem with the UPCI. Or at least tell them to try this first. Had I done this from the start, would have saved time and a lot of reading/posting.

@silvergamer said in Retropie/Odroid xu4 controllers configuration:

But yes, the odroid xu4 came installed with retropie and emulationstation.

We don't support systems sold with RetroPie/EmulationStation & roms. You can install RetroPie on Odroid XU4 as indicated here, this will get you the most recent version of RetroPie.

Sorry, no idea.

@meltedpineapple ya, that’s what i meant by

ignore the analog part

but i probably should have found / written a more relevant guide !

@mitu Yeah, unfortunately even though they are physically different PCBs, they detect as the same type (Generic Dragonrise USB Controller)

@thegreatmikeo good to know about the Xbox one controller thank you 🙏🙏

Based on a few YouTube videos, it appears 8bitdo controllers do work with iOS when adding the controller using the accessibility settings.
However, I’m not sure if that method has downsides over the regular Bluetooth device recognition.

In case it helps someone else, here’s a review of the 8bitdo working with iOS. The video creator explains how to add the controller with the accessibility method.

@buzz oh wow I would never have considered the multi tap options as they've never affected it before! That worked better than expected, now I've got analog on psx that I've never ever been able to get working. Thanks for your help!

I've managed to plug 5 controllers via Bluetooth but never gone beyond that. Honestly donno if we noticed any lag or whatever, but this was on an older pi3b, which I think has weaker Bluetooth.

Depends how fussy people are, if they just want to play bomberman and have a laugh, I doubt they'd notice the lag. If they're hardcore online gamer types, maybe go for usb controllers and a hub.

In terms of games, the pc engine has capability for 5 player, but it's just bomberman which you've already got covered.

Look for a micro machines j-cart ROM on megadrive, that's 4 player I think. Also arcade beat em ups are fantastic 4 player, Simpsons, turtles, X men (6 player!), There's tons of them but I can't remember them all.

Edit:- just use this list for games btw, it's pretty exhaustive:- https://retropie.org.uk/forum/topic/4336/list-of-retro-games-for-4-players

The BlueMSX doesn't have any control mapping for keyboard, only for joypads. It expects a keyboard for keyboard input. The FMSX core has some extra options when mapping the controls and setting the Device Type to Emulated Keyboard, but it still doesn't cover the full keyboard (only a few F keys, Esc, Space, the direction arrows and Space).

@crossmr I managed to get the controls reconfigured, however the graphics option"MaintainAspectRatio=1" doesn't seem to work in the config file. Right now the image is stretched to the sides, instead of maintaining the proper aspect ratio.

@dankcushions

ok i did that, i hope it fixes it

Uh dang, I need to make some retractions here.

I went back to re-examine the joystick circuitry and stuff and it looks like the thumbstick works fine at any voltage. (I felt my logic was odd when lying in bed the other day). The "lopsided-ness" I was talking about is actually caused by setting the range incorrectly. Ignore what I said for #1 in the previous post. The thumbstick appears to behave the same with 1.8V as with 5V (from a design standpoint, you'll probably save a little power by driving it at 1.8V).

Most modern joysticks expect something in the range of -32767 to +32767 with the center/neutral point (when the joystick is not being touched) being 0. Why? Because this is the min and max values you can represent with a signed 16 bit integer. To be extremely pedantic, you can actually go to -32768, but we pretend it's -32767 to make it symmetric.

When I did the mapping function, I take an input range of values going from ~70 to ~325 to 0 <-> 16384. I think this is where the "lopsided-ness" comes in. I'm using a built in function from the Arduino library called map() so I don't exactly know what is going on, but it places the center point somewhere around 4000 instead of ~8150 as you would expect. This isn't a problem if the output range is -32767 to 32767 for some reason.

Thanks. I changed the power to a new official one and this has solved the lightening bolt issue. However the controller cutting out remains.

No matter what I do, as soon as I connect a second controller the light goes out on the first one and controller one cuts out. Its driving me nuts. Can anyone help please.

@djmoss I am so glad that things are working for you now. Happy Holidays!
