GroovyArcade live-CD 2022 (collaborative effort)
wigginjs:
Hi all, super excited about using this project for my arcade build! Thank you so much to Calamity, Substring, and the community for this project.
I've put the GroovyArcade 2021.03 release on a USB key and I'm using it with my an HP desktop that has an i5-3470 processor and 4GB memory. This system has onboard video out (DVI and VGA), but I've also installed a AMD Radeon HD 5450 card in the PCI-e slot. I'm using a HDMI -> Component transcoder to connect to my standard def Sony Wega (KV-36FS130). The transcoder looks like this one ( https://www.joom.com/en/products/5aff9eea8b451301c9b8f471 ) and I'm also using it with a Raspberry Pi 3, outputting 240p to this TV with no issues.
I can get video to display by using the HDMI output of the Radeon and selecting the NTSC option during USB key boot. I'm able to use this to complete the GroovyArcade install to my hard drive. But, when I boot from the hard drive, I just get grabbled video from Attract Mode and even when I hit ESC and go to the text configuration menu. I was able to start getting video output from the text configuration menu by editing the /boot/EFI/syslinux/syslinux.cfg file and specifying 640x240S as the resolution. It was blank before this. I've also tried going into a game from the Attract Mode menu, but I still get grabbled video. Any idea what I might be doing wrong?

I remember how much work it was to set up my arcade machine 15 years ago. I have no idea how many modelines I calculated back then.
And when the PC died some years ago I didn't want to go through that again. So my machine stood there until I found your project and with this it was almost no work to make Mame work again - Thanks for that.
But now that I'm hooked I also want to run my old Amiga games again. FS-UAE runs fine but not in the native Amiga resolution. Therefore my question is what is the best way to run an emulator like fs-uae in a certain resolution?
I thought I'd found the answer here https://github.com/antonioginer/switchres, but these arguments do not work with the switchres version of GroovyArcade. Do I really have to compile a newer switchres version and is there a risk to mess up my working Mame setup when doing so?
Thanks in advance

Hey! Glad you like it :)
FS-UAE is ... complicated. I've already looked in how to get SR implemented inside, but it's really really complicated. As the Amiga could output almost any resolution, using a loader like switchres won't help much, but here is how you should do it !
* The repo you've mentionned can somehow be implemented inside GA by installing the switchres-git package. In that case, you'll then have to set your monitor by editong /etc/switchres.ini
* Using this version, you cvan use switchres as a loader : switchres 320 288 50 -s -l "fs-uae rom" is an example for 320x288 on a PAL system (as the Amiga is mostly PAL)

That's a starter point, ask for more help if you need

Mmmmmmhhhhh when the USB booted and GA went through the detection of the screen, did you choose the right monitor from it ? Because having video= empty is not normal. Or I have a bug with digital outputs (which is possible because I didn't test them, really, I only care about analog outputs). That said, grabbled output is probably because it was outputing 1024x768 as video= wasn't specified. Try with 640x480iS or 720x480iS (which is the value of the NTSC option on the iso). Are you sure your TV is NTSC only ?

Thanks, Substring! I’ll try that when I get home. Yes, the TVs I’m using a standard def US televisions with component input. Is GroovyArcade typically only used with real arcade monitors and not standard def televisions? I’m curious how most people are transcoding RGBHV to YPbPr if they are using a standard def television. I’ve found some transcoders, but they are much more expensive than the HDMI to YPbPr device I’m using.
Substring:
I don't have much knowledge about TVs in USA, and if thy can only do pure ntsc or they have some tolerance. The purpose of my words was rather to say that Games will be forced to the exact NTSC vertical refesh rate. Games like rtype or mortal kombat won't feel like the exact original.
Although GA is indeed for arcade cabs, tvs are supported. Just know the limits of a tv compared to an arcade cab ;)
