@edmaul69 said in I need help using a scanline overlay on a CRT:

@simillarian @starquake @dankcushions @Floob i added this in my /opt/retropie/configs/nes/retroararch.cfg

video_fullscreen_x = 320 video_fullscreen_y = 240

and i got it in fullscreen 320x240. wouldnt this fix @simillarian 's problem? i also removed the video setting from run command menu right before a game starts

That won't work. There are three resolutions used when emulating games using retroarch on a Pi. The game resolution (e.g. 240P), the retroarch output resolution (could be 240P as in your example) and the resolution that the Pi uses for it's video output (for composite it's 480i or 576i) which is set in /boot/config.txt. Let's assume 480i in this discussion.

The problem is, even if you get retroarch to output 240P, the Pi will upscale it to 480i and alternate displaying odd and even lines on alternate frames. If you emulate scanlines (by shader or overlay) you will lose either the odd frames or the even ones effectively show a blank frame every other frame. As starquake said, this effectively cuts your frame rate in half. If you have a game that relies on showing or not showing something on alternate frames for transparency effects, you'll only get to see those frames that show (or not) something and the transparency effect will be lost. Even if you don't use games that rely on transparency, you'll only be seeing half the frames which will spoil animation effects and make the screen seem to lag.

@simillarian, You say you have a Trinitron TV. Does it have some form of RGB input? If so, you could use a HDMI to RGB adapter or a Gert VGA adapter to enable you to get a 240P signal you could feed into your TV.

Wow very useful tip. I am very new to all this.
Thank you very much!

@Dochartaigh yes. A lot of the genesis cables have loose pins and these style of connectors generally have a tighter fit.

I was reading through this today and found the following steps worked for me..

Go to your retropie menu
then select retropie setup
then managed packages
then manage optional packages

then install from binary

The Amiga and Dreamcast then installed onto my retro pi once I rebooted it

@hansolo77 said in Problem with Genesis/MegaDrive USB adapters (RetroUSB and Mayflash brand):

Would you be against buying a 3rd party controller?

I'm a stickler for the originals I must say. I've had bad luck with pretty much every single after market controller I've ever tried going back even to the 80's. Even had bad luck with 2x 8BitDo's everybody seems to love. Only lately, ~20 years later, am I having problems with the real console controller brands for the first time (and even that's not their fault as they're now antiques, and I'm using them on a computer and not a console).

@edmaul69 said in Problem with Genesis/MegaDrive USB adapters (RetroUSB and Mayflash brand):

the biggest issue is the cables are crap.

I'll deal with re-wiring them if I have to, in like another 20-30 years when the controllers are going for $100+ each because they're so rare ;)

Right now I have working properly: 4x+ NES controllers, 2x SNES, 3x Genesis, 2x PS1, 2x PS2, and a bunch of Xbox 360 wireless controllers....so even though it took me a ton of trial and error I have at least a set for each proper console I emulate so I'm just leaving it at that. It was just a shame that it took so much trial and error to get to this point. I want to have a 2-player set of controllers for each console, and a backup or two so I'll probably pickup another SNES and Genesis controller, but that's about it.

@BuZz Thanks, yep I was using the Samba-Shares option, but it was weird, initially none of the folders or files under roms, bios, or configs were showing.
After leaving it up for several hours then coming back and trying again, it let me get into the roms folder, so I deleted a few Dreamcast roms, and it's working now. very odd.

@sabelstrom

Here is my pictures.

On this boot i got a bad resolution and i do not know why..

So the one in the link does work or not?

EDIT: found other Your posts, so it's the working one :)

@meleu Tried to replicate the issue one more time and now its working fine.

bangs head against desk

After entering 'attract-mode' into the command line, I was able to get it to work. There doesn't seem to be any art readily available, so I'll follow Floob's video instructions on how to download everything into the required folders. I'll ask for help again if I run into any other problems.

Thanks :-).

@bassman6805 Install the xpad driver from RetroPie-Setup -> Manage Packages -> Drivers and it will make the triggers act as buttons and you will be able to configure easily in ES.

It's still a step in the right direction. I think once I get my controller problems all sorted out, everything will be fine. What I'll probably just do is use your Joystick Selection tool and map everything out to just use the Xbox controller, and then the NES pads just for NES. I can still go back in and change that to the Xbox controller in the future easily enough, so I don't have to worry too much about using that "on-the-fly" method.

Hi, I'ven been playing around with connecting a ps4 to retropie. The wike from FreakyBigFoot was a very big help. Like it sad, i borrowed 2 controllers from my friend, one newer , so i needed to use the ds4drv.
Today i bought my own new controllers, wich turned out to be the new version 2 (light bar on top of the touchpad and grey buttons).
I disabled ds4drv on startup in rc.local, connected both in the bluetooth menu, and they worked fine! buttons get registered.
(with the ds4drv i couldn't connect the second one)
Maybe someone else can confirm this. I just tought to share this so someone could put it in the wikki to help other people.

Thx for all the help, especially FreakyBigFoot

ps i also did the firmware upgrade discribed on the wikki of FreakyBigFoot , maybe it matters

@XD3l I don't know if there stuff is also in the US but some electronic warehouses sell Xmas calendars for electronics.
There are 24 doors to open and behind every door there is a new (very small) project to build. Here is a list with experiments :) and I think there also is a kit for the Raspberry Pi online :)

Edit:
The kit with RPi experiments

Answering my own question. I will start a new thread with full usage
