Start up tv when RPI powers up?

I tried it. It powers up when held... stays on. I put in a foot switch to test while holding the power button. Popping the floor switch on and off while holding that switch down worked a treat. So I guess at this point I just need to jumper that power switch.

Now that is an awesome idea too. How do you solve the shut down issue with the RPIs? The fact that you *could* get corruption through poor shut off? Or do you just go thelma and louise on it?

you could move roms and things you absolutely positively need writable (some config dirs, maybe?) to usb, symlink their original paths as needed or change where whatever frontend/emu you're using looks for them, and make the sd card read-only.  then at least any possible corruption issues are more likely to be limited to the specific file that was being written to.

So I jumpered it. Got out the soldering iron and that's that. Works as you'd expect. Power goes on... tv is on. Sweet. Sweet. Sweetness.

Now I just need to quit screwing around with the RPI and toss it in there. I don't have controls for this cab yet, but at least i could run some sweet 80's videos off of Kodi in the background :-) This will go in the Space Encounters machine there in the middle. Someone gave it to me about 10 years ago... non working... some parts removed. I tried trading it off for years, but no takers, so It's headed into emulator land. Going to set  up the existing controls intact as a hot swappable set, but usually it will just use a tastefully done panel in a similar style with a joystick and a few buttons for most things. Man, I need to finish those 4 cabs up. Various states of disarray. Whatever... it's a basement ;-) Nobody comes down here but me.

I hot plugged the Raspberry pi probably 200 times while I was originally learning all the ins and outs of it and never *noticed* any issue. I'll probably just make a backup of the initial image and then just say "screw it" for awhile. Eventually I might go with some nicer raspberry pi switch to run the whole thing. Who knows. Problem for another time.

 

mahuti:
The only downside to this method (on this TV) is that it blocks the function of the remote control. Weird. Whatever. If I need the menu sometime I can just cut the jumper or desolder it.

vinegar:
put a rocker switch inline lol
