Try flexing your HDMI cable upward (away from the Pi PCB). I am currently having some issues with conductivity with my HDMI connector and flexing it up fixes it. Or you can try another HDMI cable.

Have you messed around with any files on your SDcard or is it the stock .img? You could try just reloading the image on your card and see if that fixes it. You could maybe try another monitor or use the RCA jack instead (for testing). I don’t see any reason why it shouldn’t be working as it runs fine for me, just to clarify you can see the Pi boot up on your monitor with the wall of text, then you can see the RetroPie splash screen, then you’re waiting ~10 seconds for emulationstation to boot, but no go?

Nice work Jonathan! I like the re-use of the power supply, great idea!

[skater_j10]

Sweet, I didn’t know that existed, thanks for that! Now if only there was a solution for RCA out… Maybe I should try some different video scaling values in retroarch.cfg.

[skater_j10]

Naw, I haven’t had time to look into it sorry.

So I took the plunge and purchased DOOM Ultimate from ID Software and was able to get a “DOOM.WAD” file, threw it in the Doom Roms folder and I was good to go! Thanks again for the help petrockblog!

I was just looking for a .wad file that would allow me to test out the game before I made the decision to buy it, but I just gave in and purchased it to make my life easier. Everything works great,  actually I can’t believe how fast it is and it works with gamepad controls too!

My only minor complaints are that I’d have to reduce my display size to be able to see the top text properly on my composite LCD and the buttons are mapped kinda weird on the gamepad but I can fix that in retroarch.cfg for DOOM, just too lazy.

Thank you petrockblog,  I had the same issue with the 3Drealms site, had to download via gog.com as well.

So I moved DUKE3D.GRP to my roms folder but it didn’t work but I tried what you suggested and reinstalled eduke32 with the “source based installation” and it worked!

So sweet, thanks again. My only comments now are: unfortunately it seems unplayable for me as it’s strictly keyboard/mouse controls not joystick and it doesn’t display through the composite (RCA) jack only the HDMI, so sad.

Yep, memory split is configured in raspi-config, default for the RetroPie Image seems to be 128 but if you have a 512MB Pi some have recommended 256 memory split.

Hey guys, I’ve done a bit of research on the Raspi forums and found that Dgen doesn’t work with Composite (RCA) video out for some reason. Switch to HDMI and you’ll be ok. I hope that someone can figure this issue out, as Dgen runs much faster that Genesis-Plus-GX (which does work with RCA out).

For now you can use:

COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/genesis_plus_gx_libretro.so –config /home/pi/RetroPie/configs/all/retroarch.cfg %ROM%

in your es_system.cfg file (under DESCNAME=Sega Mega Drive / Genesis) to be able to use RCA video with a Genesis emulator, Sonic is unplayable but at least there’s columns.

ooops posted master system twice, here’s the game gear settings:

DESCNAME=Sega Game Gear
NAME=gamegear
PATH=/home/pi/RetroPie/roms/gamegear
EXTENSION=.gg .GG
COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/genesis_plus_gx_libretro.so --config /home/pi/RetroPie/configs/all/retroarch.cfg %ROM%
PLATFORMID=20

[skater_j10]

Here’s what I changed my es_system.cfg to in order to have fullscreen Sega emulators when hooked up to RCA video:

DESCNAME=Sega Master System II
NAME=mastersystem
PATH=/home/pi/RetroPie/roms/mastersystem
EXTENSION=.sms .SMS
COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/genesis_plus_gx_libretro.so --config /home/pi/RetroPie/configs/all/retroarch.cfg %ROM%
PLATFORMID=35

DESCNAME=Sega Master System II
NAME=mastersystem
PATH=/home/pi/RetroPie/roms/mastersystem
EXTENSION=.sms .SMS
COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/genesis_plus_gx_libretro.so --config /home/pi/RetroPie/configs/all/retroarch.cfg %ROM%
PLATFORMID=35

DESCNAME=Sega Mega Drive / Genesis
NAME=megadrive
PATH=/home/pi/RetroPie/roms/megadrive
EXTENSION=.smd .SMD .md .MD .bin .BIN .zip .ZIP .gz .GZ .bz2 .BZ2
COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/genesis_plus_gx_libretro.so --config /home/pi/RetroPie/configs/all/retroarch.cfg %ROM%
PLATFORMID=18

I used the original Genesis-Plus-GX emulator that Petrockblog chose (instead of Osmose/Dgen) which works perfectly except it is causes a slow down with Genesis/Mega Drive ROMs. Dgen works full speed for Genesis/Mega Drive ROMs but doesn’t seem to work with RCA video out for some reason, if someone knows how to configure this please let me know.

P.S. The “COMMAND=” code should be on one line, the wordpress editor forced it to 2 lines because it was so long.

@yodapwnedjoo If you’d like to get the LXDE desktop functionality back, just plug in an ethernet cable to your Pi (with net access obviously) and type “sudo apt-get update” and when it’s done type “sudo apt-get install lxde” you’ll be able to startx after this is complete.

I’m not certain where the wifi configuration settings are as they are no longer on the desktop (as the regular Raspbian install has), but hopefully this helps.

@petrockblog, yeah I’d personally like to see LXDE back on the SD card image, it makes it handy to use RetroPie as a gaming system interface and then drop-out and use LXDE as a PC interface when needed. Thanks for providing the .img by the way, it makes it so much simpler to allow users to get up and running quickly with Retro gaming on the Pi!

@Wysee Are you overclocked to 900MHz (you might still be at 700MHz) and what’s your memory split like? 256? Do you have a heatsink on the CPU?

Change your Pi hardware options with “sudo raspi-config”.

I tried placing the exec.bin and grom.bin files in my Retropie>roms>intellivision folder but I’ve still had no joy in playing ROMs with this emulator. I tried 6 different ROMs just in case, but nothing.

I’ve also tried to adjust the resolution from -z0 to -z1 in es_systems.cfg to match my RCA LCD screen resolution but to no avail, everytime I try to load a ROM it spits me back to the intellivision emulator menu.

Anyone get this working? I’ve been up and down the link that Petrockblog provided but haven’t found much more that is helpful.
