hey guys!

so i managed to get this to work to some capacity but few things are a tad wrong and was hoping for your help.

when i power the NES on, the push button is OUT when the unit is on and when i push the POWER IN, it turns OFF.
is there something anyone can think of to reverse that? I've tried moving cables around and can't seem to get it.

how does one get the LED to work with the unit if its built in on the board? should it just not turn on and off if i ave properly tapped into the power?

thanks everyone

@kmickelow You could start by telling us a few things about where you DID get your image. Is it the RetroPie 4.2 image?

Then, tell us all about your setup by following the link at the top of every page here.

@jmperez

More information about your setup will probably be necessary. The required information can be found at https://retropie.org.uk/forum/topic/3/read-this-first. Also at that same link, take note of the part detailing how to format your posts for log entries.

@simonster I had totally forgotten that I used a USB to transfer the last time and not the SD card. This should fix the problem. Thank you!

Hi chipsnblip
Yes u possible can do it with that d3scription in ur link. I'm wondering if anyone has successfully burnt a big gig pi image with games and boxart tge lot onto an external drive and it worked.

I've been chatting around on forums for past few weeks and talking about this and alot of people have said no u can't boot the image off ex hdd u need a 64gb 128gb or 250gb sd card. As it's not possible to run it off external.

Just done it myself in about 5 simple steps. With help and info from Internet of course

Just wondering as I've made my own image with games art and stuff put it on external and plugged into pi and powered on and it booted up and works.

Has anyone else tried it instead of going the long way round and inputting lots of data into the pi terminal to format scan re partition and to auto mount the usb drive.

Okay folks, I've written up a script to handle this exactly the way I described before.

It runs from the autostart.sh and watches /dev/shm/screen_manager.cfg for updates.
That way any other system process can create/modify that file and this script will respond by either starting the rom, or starting the dashboard.

Cheers!

@BuZz can you recommend a browser? I tried this in google chrome and internet explorer and they both give they same results, they only hold the first group of threads in their memory. I think a work around would be to scroll through each grouping and do a print of that, Looks to be about 10-12 posts per grouping. Thanks

@AlexMurphy I had noticed that there was nothing interesting, however, the log was requested to me and I'm not so confident to think that I know better.

Here's runcommand.log, it seems that there's nothing here too.

Another question. When I map buttons in Retroarch, do i still need to hit the tab button on my keyboard to enter in other inputs while in a Mame game?

@AndersHP said in lag lag lag, I hate it, just ran a lag test and am disappointed with RPi/retropie:

@rig I believe all of them can be changed in the RetroArch menu. You do need to save them for turn to be applied when you restart RetroPie, so depending on your setup you may want to go straight to the config files for that after you're happy with the results.

Does this mean that they wont be applied unless you save and restart? Or do they apply instantly but get reset if not saved? Sorry if it's a stupid question.

I believe that the changes are applied immediately but as soon as you exit the game/retroarch you lose the changes unless you save them. You can verify this by making changes, exiting the menu and the reentering the menu and checking to see if your changes are still there.

Thanks. When my new controller comes in the mail. I will retry it though the retro arch menu. If that doesn't work. I'll just manually​ edit the config file.

another thing you can do is change the retroarch video driver to dispmanx which is said to save 1 frame off the input latency. i haven't personally done this as it has some side-effects (no shaders, no OSD, no screen rotate)
