i use my Pi-Models 1-3 with CRTs (1x Samsung / 1x Bang&Olufsen)
Of course i wanted to connect the Pi4 also with my CRTs, but i only tried it once and burried that idea.
At least concerning the composite out.
Maybe i had bad luck and my Pi4/the AV-socket is broken, but the picture was H-O-R-R-I-B-L-E!!!

I am still searching for a verfied method to connect with better quality (Gert666, Pi2Scart etc.), but did not find anything that runs out of the box without any issues or performance loss :[

@windg said in Extract region of games via command line:

You can take the hash of the rom and compare it with a database. For example this site : http://redump.org/ have the hashes of the games of a lot disk systems.

Unfortunately that site does not have retro games listed. Only PSX, Dreamcast and up. However the m5 hash approach gave me an idea: I can download a rom pack and compare my roms to the ones from the pack. Thanks for your helpful answer! :-)

Unless you're connecting your Pi using a composite cable to your TV (which seems unlikely, since that won't do 1080), NTSC/PAL is not an issue for TV's video resolution.
Use raspi-config to choose your desired video resolution globally or modify your /boot/config.txt according to the Raspbery Pi video doc.

@dankcushions Yeah, the ROM I used was one I just had lying around from years ago when I first got into emulators. The emulator I used back then worked with the game fine, so it's probably just an issue with QuickNES as you've referenced. I've decided to use NTSC in the future. Cheers!

Hi, thanks. I actually got some help from @muldjord to fix this issue. I'll try to find the thread and link it to here.

[edit]
Here it is. I managed to scrape almost all my troublesome roms using the method @mitu and @muldjord show in this thread.

I don't use mu .LHA files uncompressed as that is the format WHDLoad uses them in. I only use .CUE when I need CD gamers with the audio.

Have just published this - https://retropie.org.uk/2019/07/composite-out-broken-on-retropie-4-5/

Vice loads in real-time, same as real hardware.
I tested this with Bruce Lee game, on both Pi and real C64 + Pi1541

check these settings as well or add them
sdtv_mode=0
sdtv_aspect=1

and
#overscan_scale=0
should be overscan_scale=1

after that try
overscan_left=10
overscan_right=10
overscan_top=-8
overscan_bottom=-4

@moltavia

Just a point of interest, Streets of Rage / Bare Knuckle isn't actually 2 ROMs but a single ROM that changes based on the language / country setting. It will even do this dynamically in some emulators and on real hardware if you have a country switch mod.

Load SOR and wait until the title sequence / back story start to play and once the story starts scrolling up, enter the GUI and change the language to Japanese and then exit the GUI. The story will continue to scroll and then change to Japanese after a few seconds.

i don't know the reason some shaders work and others don't, can't help you there sorry. but my best guess would be they are too powerful for the pi/ARM architecture and fail silently. with regard to this particular shader set, you might want to try using the files from the repo as they were just updated yesterday to "fix dumb typo" https://github.com/libretro/glsl-shaders/tree/master/ntsc

@darksavior

Well I updated it about month ago when I finished my PiStation build, has there been any updates since ?

@katemonster Hey katemonster, I hope you see this. I'm doing something a lot like this. But I want to use the RGB instead. I found two diagrams that are pretty different from each other for how to get RGB from VGA to the input of the LCD. Do you have information on this?

One diagram uses 270 resistance to intersect the combination of VGA pins 14 and 13 with the green, but only uses one VGA ground pin. The other diagram includes no resistance, uses 3 ground pins from vga. Neither worked, and I've been trying for a week. Its possible they didn't work because of my breadboard, or contact from a wire MAY have been bad when I tested. But I haven't been able to find information that anyone has verified to work. You definitely seem knowledgeable.

@TheJullasicFox It's finished now, but I will make edits later, like a functional power button and reset button Thanks for joining me!

Okay, It's been FOREVER, but I'm coming back to this project. I am going to order the parts soon. This forum isn't dead!
