@substring said in Commodore 64 on a CRT via RGB?:

How do you want us to give you some help (because we do have some hints there, maybe not what you're expecting) if you're just behaving like that ? Do you know how often Recalbox users have been spitted on from the Retropie community ? on IRC, Reddit ? We are not that kind of people here, but that message i quoted hardly gives me any motivation to help you.

1. No, I do not know anything about Retropie users attacking Recalbox users. If it happened, it's pretty sad but I do not count myself as a member of a "Retropie community" - I simply use their OS. That is all. I have no interest in petty forum wars, I'm way too old for that.

2. If you want to use that line form my post you quoted as some sort of proof of my arrogance and excuse to go on the defensive, feel free to do so. Anybody else reading this may observe that it was your fellow mod who started shouting at me and causing drama first, for no other reason than me asking a question on your forum while admitting (and explaining very clearly my reasons for doing so) that I use some other OS.

Therefore I advised him to simply thrash this thread and yes, I very much did comment on his arrogant and unhelpful attitude . I'm 40+ years old and I really have no time for unwarranted hostility. And while I would love to resolve this problem -one of your forum members knows how to do this - I guess that's not gonna happen here, so, again: could you please kindly close and delete this thread, sir?

Yeah, I also said:

Since microcomputers are nowhere near as popular as old consoles, information on this subject is very scarce and despite searching all over internet I failed to achieve this.
Seems that the only person on the planet who may know how to perform this feat is @ironic, hence me posting here even though I use Retropie (though I don't think the OS choice really matters since the core settings are universal)

tl; dr: I'm desperate and this forum is my last resort

I've opened this thread following @ironic's advice: https://forum.recalbox.com/post/66944

To answer your question: no, it is not a big problem for me to ask for help on a different forum after exhausting all other options. What's the big deal? Like I said, this issue is universal and even if there is no C64 in Recalbox now, it may be one day.

However, if this is a problem for you, do not hesitate to thrash this thread. Your welcoming and helpful attitude will be duly noted.

I've been struggling for weeks to display perfect 1:1 C64 image on my CRT TV. Since microcomputers are nowhere near as popular as old consoles, information on this subject is very scarce and despite searching all over internet I failed to achieve this. I got very close, but as anybody obsessed with 1:1 CRT pixels knows, "close" is not good enough.

Seems that the only person on the planet who may know how to perform this feat is @ironic, hence me posting here even though I use Retropie (though I don't think the OS choice really matters since the core settings are universal).

My setup: RPi 3B + Pi2SCART + 29" Sony Trinitron + Retropie 4.2
I use these hdmi_timings=320 1 15 20 49 240 1 6 8 10 0 0 0 60 0 6400000 1 values for my other emus such as horizontal MAME and retro consoles. Using the 1600 pixel trick they all display perfect 1:1. When tried with microcomputers problems start (probably because these are not within Retroarch?) C64 image has artifacts when perfectly centered...1:1 look is possible, but then the image stretches beyond the screen horizontally (about 20-30 px each side) and has some borders on top and bottom.

I've tried the hdmi_timings=336 1 10 18 46 288 1 5 6 6 0 0 0 50 0 6400000 1 values suggested by @ironic but it still doesn't work for me. I suppose the answer may be in VICE settings - there are numerous ones in Video section. I tried most possible combinations though...

This issue i driving me mad...so any help greatly appreciated.

@ironic said in AMIGA CD32 EMULATION - HOW TO -:

For Commodore 64 50Hz(Vice - Combian 64 edition) i use :
hdmi_timings 336 1 10 18 46 288 1 5 6 6 0 0 0 50 0 6400000 1
(so, 336x288)

D**n...I was hoping it would work, but still no luck. Thanks though!
May I ask what settings in Video in Vice do you use? I mean: Size Settings/ Fullscreen Mode/Custom Res/Res limit mode/Open GL
Also, the Border: Full, Normal or None?

My hdmi timings generator only works with RGB/GPIO.

I use pi2scart, do you think it may require different settings from your setup? Also, I use Retropie...maybe the difference is in that Vice Combian 64 edition? I'm downloading it now, will try later.

@ironic said in AMIGA CD32 EMULATION - HOW TO -:

I use VICE and it works nicely but it must be setup a lot to have a true fullscreen, no tearing result.

Thanks for replying. How do you do that ^^? Also through GPIO solution?

I had a feeling that maybe resolution from Vice is 384x271 (overscan) since it goes outside the screen, despite my hdmi timings being set to 320x240
Could you advise how would I calculate hdmi timings for this (384) resolution? I saw your python script somewhere but not quite sure how to use it.

@ironic Any chance for a hint how to run Amiga or C64 on a CRT via Pi2Scart?
With Amiga, the emulator UI is blown up in some super high resolution and I can't do anything.

With c64, it's better, but I struggle to hit 1:1 pixels. The best result I get is 1:1 but with borders on top/bottom in horizontal, and going slightly over left/right in vertical.

Not sure if it's controlled by hdmi_ settings or maybe somewhere in the emu?

@ironic Hi mate, your posts are one of the reasons I'm in this thread Thanks for replying.

You might just be right, I never saw settings for 480i anywhere so may be it's not possible. I've been told to do this by one of the experts on shmups.org forum, but when I asked for details there was no reply.

What would you suggest, is there any other way to play vertical games using GPIO -> RGB...but without rotating or buying another CRT just for verticals? I'm currently looking into Advance MAME...

Hi folks. I need advice with one issue that I can not solve and have seen some people in this thread who might be able to help. I don't actually use Recalbox but RetroPie, but I hope you don't mind since the problem is universal. I will also consider switching to Recalbox if that's necessary.

Here's the problem: I'd like to know if it's possible to display vertical MAME games on my Pi2SCART + CRT TV setup, but without having to turn my 50kg TV on the "length" side every time. This means that there would be black bars on left and right but that's okay.

My current settings (240p) handle all the other platforms and horizontal MAME games just fine. Naturally, using these settings causes the vertical ones (>240) to be either squashed and ugly, or stretched outside the screen, losing big chunks on top and bottom.
I've been advised to use a 480i mode on the Pi (so the vert games would "fit") but can not find the proper hdmi_timings for that anywhere and am reluctant to experiment (already lost one TV doing that). Was wondering if anybody knows of a solution?

I'm using Rpi3B + Retropie 4.2 + Pi2SCART + 29" Sony Trinitron. My current settings are the usual ones from the 1600px fix found on RetroTink, Arcade Forge and other sites.

Thank you in advance!
