I'm having a similar issue. Thought I'd post here rather than start a new topic, hope that's OK.

My problem is the game starts up and runs fine as long as I leave it in demo mode. The demo loop runs the video and sound just fine. But when I start a game I see Dirk run across the bridge and then the screen goes black. I can hear the game running but can't see anything. By pressing random controls sometimes I'll get the death scene or if I'm lucky, a level I can actually play before it all goes dark again. I've deleted the .dat and parsed many times with the same result.

I'm hoping someone can help me sort this out, thanks. Here's my ls output:

@Carbooja no. see http://commonmark.org/help/ (Three backticks for code blocks)

Ah ok thank you. So basicly i neet to change the command to

subprocess.call("modprobe --first-time -r db9_gpio_rpi", shell=True)

and import the subprocess?!

@herb_fargus

do you live in tualatin?

lol unfortunately no, it's only my first PC PIII(Tualatin) name, that i take as nickname.

Does emulationstation work just from the terminal by typing in emulationstation?

yes it works, but now i have another problem, my sixaxis dont mapping correct, can it be a problem of internal bluetooth in my laptop, i need to use external dongle ? Whith my usb controler it work fine.

@dankcushions said in MAME2003, Rgui vs Tab:

when you press tab, where are those control configurations stored?

https://github.com/RetroPie/RetroPie-Setup/wiki/lr-mame2003#mame-menu

They appear to be tied to the retropad mapping so how do they work with the Rgui bindings?

basically all libretro emulators only see the retropad abstraction. so regardless of what controller you use, the emulator will only see 'Retropad A button', 'Retropad B button', etc. if you rebind something using the TAB key, what you are saying is 'Button 1' in mame is changed from 'Retropad A button' to 'Retropad B button', etc.

Perfect, thanks! I missed this in the Wiki.

Ok I fixed this! :)

So for anyone that has this problem in the future this is what I have done:

Update the Retropie script in the retropie config menu Set the screen resolution & shader I wanted to use in the config menu Update from source the kid friendly emulation station add on (I tried uninstalling it first but that bricked the image) Test everything is working, Which for me it now appears to be :)

Rbaker, Thanks for your input.
The kiosk mode I refer to is a experimental emulation station that allows the retro menu and a few other things to be locked out to make them child friendly.
I will also look at getting a bigger PSU.
Thanks.

@MacEns Try going into /boot/config.txt and remove the hash symbol at the start of config_hdmi_boost=4. This will increase the HDMI signal. Or swap out the cable. If it is displaying on and off and your TV is giving you that warning I would say that is your issue. This value can also be changed up or down.

@Murderlol Ah, cool. Glad you got it sorted. Thanks for replying. It just helps others who search the forum with similar issues.

I can't access it but still I know that You can override it by just copy pasting text on the cell with data validation :/
Still just disabling any editing option will work fine. I don't trust any of those sheets but for me they are a list of compatible roms.

@batesman the list file is if you want a custom set of choices. You can manually specify which images you want it pull instead of the whole folder

@wropzter are you able to help a newbie out here... How do I install this? I've spent 2 days trying to get mine to work through xboxdrv running into same issues you had. This would be a life saver!

@actnash Also, just wanted to say that for the pi 1, quicknes and pocket SNES are the two emulators that are working great for me. Yoshi's Island runs almost full speed, with occasional stutters, but super mario world runs flawlessly. For NES, OpenGL driver, max swapchain= 1, video hard sync on =0, and frame delay=8. I got a NES classic for Christmas, but with these settings on the pi, it's very hard to tell the difference between the two. Graphics, input latency, and everything else is very comparable which is AWESOME. For SNES, Max swapchain=2 and frame delay=4. Turbo overclock makes all the difference for SNES.

@SohailNassiri No problem. Again. I'm just sitting watching YouTube and doing not very much. Happy to help. Most people on this forum are more than willing to help out someone struggling but they do expect you to read the resources available and to provide all the info needed. Simply because everyone's set-up is so different and there are so many variables that it can just turn into a guessing game sometimes. Anyway, good luck. If you encounter any further issues unrelated to installation I would advise you to search the forum first then start a new thread if you can't find a solution.

@smiler79 It shouldn't be. Is the PSU ~2.5Amps? Is it a hardwired dedicated PSU or a plug and USB cable combo? Some USB cables just cannot transfer enough power as they are designed for phones and tablets that draw a lot less juice.
