@Folly Thank you so much for the info!!!! I'm going to buy a better power supply.

@mitu said in Pi4 - My red status led remain "Consistently Lit" also after shutdown.. it's normal ?:

Another question it's... how i can identify my actual hdmi cable if it's unidirectional or bidirectional ?

Never heard of 'unidirectional' HDMI/HDMI cable, but you probably have a regular cable, which can be plugged either way.

I have found some on amazon.it but noone whit a clear description of also whit a explanatory review :)

When i can I try to ask my trusted electronic parts seller :)

@Yornav No for Retroarch cores, as far as I know. Maybe for some version of advancemame, but I have not look at it. They will work if you compile the latest standard mame, but it will run very slowly on the Raspberry.

@SigmaX what OS are you running in the Pi3 ?

@cyperghost Excellent ! And thanks, I'll try it :)

@orehruoy I think what you might of had problems with is the shutdown type button you use with the shutdown script is a single press sprung button to inturpt the signal/make a signal. ( squid button)

Sounds like the mega drive button is a switch which is why it's changing around each time.

Can you share a script that will send the current game name to the LCD matrix? I ordered 3x LCD Matrix from AliExpress, size 64x32 px (192x32). I would like to display either a text with the title of a game or a wheel-playing game.

I will try to set up the settings according to these instructions: https://github.com/hzeller/rpi-rgb-led-matrix/

I use this board to connect to Raspberry GPIO : https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-raspberry-pi/

@sturbek I dunno about turning off a USB port, but if you are using a powered hub, you could trigger that on and off via GPIO as you suggest. Nothing is built into RetroPie to do this--you're gonna have to build something from scratch.

A recent MAKE article was published with details about how to go about it with a relay:

I have a question,
could you manage to get a GPIO output to toggle from high to low or vice versa when something happens in the game? are there any methods to detect if gameover or highscore happens?
I ask because I have RGB mood lighting on my cabinet, and would love to make it flash and strobe etc if you die or get a highscore etc.

I understand that detecting an emulator starting and detecting what happens inside the emulator are two different things, but you dont get if you dont ask :)

For anyone interested, this has been tracked down to the use of an external Bluetooth dongle and having the onboard Bluetooth disabled with dtoverlay=pi3-disable-bt.

The retropie_wiimote_lights script by pyhammond works fine with the onboard Bluetooth. Fingers crossed they can sort it for an external Bluetooth dongle as well as it's a really useful script for people with WiiU Pro controllers!

Thanks.

good to know. Once again thanks a bunch.

Oh... for easiest plug and play from a Pi, you probably want a controller board that identifies as a keyboard, or as a 360 controller. There are many of these on the market. Watch out for some gotchas with ones marketed as Xin-Mo, there are actually several makes being sold under that name and they aren't all the same (Paradise Arcade in particular carries ones labeled Xin-Mo that may require a fresh kernel compilation).

I don't plan to have every game launchable via Amiibo. That would be insane. I'm just configuring it to launch specific games based on the Amiibo scanned. For example, right now Zero Suit Samus will launch Metroid Zero Mission, any Link Amiibo will launch Link's Awakening and any character's Golf card from the Mario Sports card set will launch Mario Golf.

@GtBFilms i had uv florescent bulbs in mine. And had bought uv reactive motherboard paints. Oh i remember the good old days of making your pc look cool. And you used it for many years. Nowadays people just buy gutter garbage they end up throwing away in 6 months.
