Use sdcard formater to wip them and select the option for the whole card remove partition or whatever it is
Sorry should have mentioned I swapped the power supply between my working Kodi Pi2 and the other Pis and the Pi2 works fine so the PSU is correct - in fact they're Rasp Pi branded ones.

I'll try your last 2 suggestions tonight, thanks.

I'm getting the correct RetroPie build for my device, imaging successfully using Win32ImageWriter, etc. On boot I get one red light for PWR but no image onscreen or progress from there - no green SD activity light. The devices were working fine when I "retired" one as my Kodi box a few months back (the other I used for RetroPi before I realised I could just swap SDs in one) and replaced it with a Pi2.

What else can I check? I tried 2 of these older Pis in my bartop with the same result, 2 different SD cards, etc. It must be something simple as in the past they've always just worked
Is the power supply up to scratch?

Depends on model and if you're overclocking.

I've not heard of anyone on a Pi2 B+ or Pi3 at stock speeds needing a heatsink, let alone a fan, regardless of what they do with the unit.

I have a multitude of Pis as gaming units, TV media players and inside enclosed arcade machines running emulators, all at stock, and none of them with any extra cooling whatsoever. They've been running fine for years that way.

Cheers, it will be a Pi3, I don't plan on overclocking, from what I can tell I don't need to overclock to run the old school games

my pi3 definately needs a heatsink when working hard. i was getting a orange/red square (like the rainbow one for power) when running 24/7 in a browser based game. i can't leave the lid on the official case even with the heatsink....

my non-contact thermal temp gun agrees with the sizzling noises of my in contact finger when i check

What temps are you getting from the gun, and are you overclocking?

thats a stress test built into dietPi, i just happened to have it handy. sadly its performance in the web game was pathetic.
it was hitting the thermal throttle as can be seen from the 74, 75, 74, 75 etc. which is the set point in that distro as far as i can tell. it does have an option to wind it up and overclock/overvolt



Click to view full size!


the 67.5 is 'in game', but i dont think its a very good distro to test under ...

anyway, that little blue ram sink has been the difference between massive throttling and not, so it works for me as long as i leave an air-gap between case and lid. otherwise it still gets toasty and starts to throttle

hopefully Pi4 brings a die-shrink and some heat reduction/headroom (for overclocking of course )

It's a bit quiet here

Slowly making progress with my Pi 3! I must say, the documentation on raspberrypi.org is excellent. I'm only using Raspbian at the moment to learn my around the system.

I like that it does have nice GUI programs to change some aspects of the system, for example it had HDMI underscan enabled, so that was an easy fix. It also has a convenient program to install software, but I quickly found that apt-get install is easier to use.

I noticed right away that the black levels of the picture on my TV were off, a sure sign that it outputs in the limited RGB colour space. Editing config.txt also resolved this and gave a peak into what else you can configure.

I've also updated all the software, also very straight forward, although it takes a while.

But one project I wanted to work on kept me busy today. I wanted to use the Raspberry Pi as a General MIDI module, substituting a Roland Sound Canvas SC-55 or Yamaha MU80 for DOS Retro PCs playing Doom for example.

The USB MIDI interface was detected right away. At first I tried GUI tools, but has some weird audio issue, massive distortion, something fundamentally was off.

So I restarted with a fresh image and got my head around the CL tools. Created a FluidSynth server and then used aconnect to route the MIDI coming in from the USB MIDI adapter to FluidSynth. And it worked! Couldn't believe that you can get this going with a few commands...

I've connected another machine that plays Doom 1 and 2 MIDI files and it sounds great. And you can use other SoundFonts of course!

Next steps is checking out the GUI versions again, mostly for doing a guide / documentation, not everyone is into CL.

And then having a go with Raspbian Lite and writing maybe some start-up scripts. But I want to document it all, so that others can run with it and hopefully make a hardware project out of it.

I've got this idea of a little MIDI box with a LCD display and a few buttons that lets you change SoundFont files, reset the Synth and things like that...

The forums there are a wealth of very clever peeps
Just for giggles, take a Jessie Lite and add the full blown GUI
https://www.raspberrypi.org/forums/v...51830#p1051830

nice insight to what makes a modern desktop and a windowed gui
i had a gui but no desktop environment for a while. just a terminal and apps running in a gui. bit of a head twister

As much as I *love* the Raspberry Pi, what you're using from a software point of view is 5% Raspberry Pi, and 95% 20 years of Debian Linux (the same foundation under Ubuntu).

Don't forget that these are just building blocks, which is why open source is so awesome. "On the shoulders of giants", as the famous quote goes. Kudos to all previous Debian and other open source devs who got us to this point.

But with that said, ain't the Pi a great way to introduce people to Linux, who would have otherwise never discovered it's power? For that, I love this little bit of hardware, and the amazing people behind it.

The software may be 95% Debian Linux, but the documentation difference between

https://www.raspberrypi.org/learning...re-guide/wifi/

and

https://linux.die.net/man/8/wpa_supplicant

And how the communities react to "noob" questions is worlds apart.

Yeah the second one is much better, it'll work whether you have a GUI installed or not.

So you show an article about a GUI written specifically for GUI people vs a site that provides a webpage fore all man pages! Firstly compare apple with apples. BUT I will concede that some people on the internet are hostile to noobs regardless of the operating system, especially in Linuxland when the person asking the question starts with "in Windows it is so easy". Instead of asking a question they make a statement that is incorrect, it should read "in windows I'm used to doing this, what is the Linux equivalent?".

Documentation varies between projects, after you have mastered the basics of the command line I would suggest looking at https://wiki.archlinux.org/ and adopting the information to your distro, as it is a great community.
