I am a subscriber to ETA Prime on Youtube. I got this email today about the M30 Bluetooth controller from 8bitdo being reviewed. Looks like an awesome pairing for this case!

Please include the information requested https://retropie.org.uk/forum/topic/3/read-this-first in when opening a support topic.
Have you read the documentation for enabling a 6 button controller in RetroArch ?

@mitu
Life saver!

I did a RetroPie update through install script (to update all packages).
That fixed my problem.

@denzilla try scraping again but selecting megadrive instead. disregard the fact the Genesis folder exists at all.

@kleenax Could you please remove @BobHarris' pictures in your post? :) It's a little inconvenient for others to have to scroll over them again. You can edit your posts via the three little bars at the right side of the posts.

You have to scrape for Megadrive.

Hey, i wanted to ask a somewhat related question: what could be the reason that my screensaver never plays genesis snaps when the screensaver is running? Every system i have on my retropie 4.4 makes an appearance as a random video screensaver and it doesnt matter if the snaps are located within the emulationstation folder or in the rom folder for the system itself. I'm just puzzled as to why my genesis games don't show it. Would it have anything to do with having changed all mentions of megadrive to genesis within emulationstation and this having borked whatever emulationstation looks to when seeking random videos?

Bumping this, might help clarify matters for several other GPGX users!

ekeeke replied to me about this, explaining the following regarding the new MAME sound engines:

*ASIC version corresponds to the chip model used in later Model 1 consoles and most Model 2 consoles. It features the better (not distorded and less noisy) DAC output and full address decoding of status register (which causes slower music in Hellfire since it was developed for the discrete chip version) compared to discrete chip version.

Enhanced version has same "enhanced" features as ASIC version + full resolution DAC (14-bit instead of 9-bit in real hardware versions) + zero busy flag time (busy flag in FM status is only emulated for real hardware chip versions). It corresponds to an "idealized" version of the chip, like it is emulated in other Genesis emulators.

The low pass filter is unrelated to the chip DAC and exists in all console models (it is implemented by analog circuitry outside of the chip). It should be enabled for accurate emulation of analog sound output (and disabled if you prefer the clear sound of pure digital emulation). Filtering ratio is configurable because it varies for each console models (also between model 1 consoles or between model 2 ones) so it's up to you to find a value that matches your own memory of accurate sound. Default value should correspond to Model 1 VA4 console.*

@hitch187 said in Sega Genesis theme:

I think, personally for my system, the Splash screen is okay, I possibly could keep the systems menu as is on the default theme, then for the game selection for each system, have a custom background for each system (Edit: I don't actually think you can do this, I may have misspoke).

You actually can do that. Since the themes are based on layers it is possible to have one global background image and put different images on top. Setting up different images for each system can be done by the old method, where you have to create a separate theme.xml in its own systemname folder. Or by using variables and have all images in its own decicated folders.
The theme from @chicuelo is using that method to display different controller and character images on the carousel but it can easily be added to gamelist view.

V2 of my toolkit may help you out. I have a script to do this exact thing.

If you take a look at my channel (in my sig) the legacy (old) version of my retropie toolkit will also do this for you.

Hope this helps!

@mitu said in DB9/Gamecon installation error:

I don't, didn't work with Berryboot, only normal images.

Thanks for the help, I'll look for a way to convert an image.

I just realized that like 5 minutes ago, just tested it and it works!
Stupid of me, but thanks for the reply!

@luisv96 said in Certain roms dont work on lr-genesis-plus-gx:

@mitu when i try to run verbose logging nothing happens

What do you mean "nothing happens"? Did you check the log in/dev/shm/runcommand.log ?

If you can give me some images of how a Sega Genesis menu and game loading I might be able help

Okay, I'm not sure what happened, but suddenly Genesis games work. I'm not sure if it was bad roms like @mitu said or if it was bad naming conventions on my end (changed both at the same time), but seems to function now either way.

Thanks again everyone for the help!
