Setting RetorArch to 240P?

[Ex_mosquito]

Hi guys. I recently made myself a CRT_Emudriver setup with a Radeon 6450 into a Sony Trinitron RGB Scart (which vm-maker sees as a 7000, not sure this is relivent..) For the life of me I can’t work out how to get a 240P image. Whatever settings I use I get this interlaced split image. What am I missing? Sorry if this is a mega-noob question. Groovymame works fine btw.

I can’t answer your question. If groovymame works, what’s the need for retro arch?

For the life of me I can’t work out how to get a 240P image.

Have you used vmmaker to install video modelines? If so, have you tested the created modes using arcade_osd to check that you have a 240p mode properly installed?

Installing the driver is only the first step...

I every case i've ever heard of a dual image is 480p/31kHz on a 15kHz monitor. So Retroarch must be grabbing 640x480@60p somewhere, and this should not happen if you set things up right. As Paradroid asks, what shows up in ArcadeOSD? Have you set EDID emulation on and installed all the modelines you need, and can see them in the list in ArcadeOSD? When you lock system modes, can you see anything you don't want in the list?

Have you stopped and disabled the AMD External Events Utility service? And ticked hide modes this monitor cannot display in display properties in windows?

Also, search for retroarch threads in this subforum. I know very little about this, but IIRC RA used to have issues switching from progressive to interlaced and vice versa, but i think they're working on that. Not sure if it's a fork or what. So if you're not using the right build you won't be able to go from a 480i desktop to a 240p game easily?

Thanks for he replies guys. One thing I noticed is when I install modes should it hang like this? I’m not sure if my issue is that W7 is recognising my 6450 card as a 7000series? Should it hang like this when installing modes?

Im using W7 Pro with a Dell Optiplex 3010

I recently built something similar for a console box with GM and RA for my PVM. I'm also using an Optiplex 3010, but a 5450 GPU.

It might sound silly but are you sure you've got the SwitchRESCRT option turned on in settings/video? It says it should switch automatically but it doesn't always and sometimes you have to turn it off and on again for it to work.

[Ex_mosquito]

Hmm I can’t see that CRT option anywhere, wierd.

Buttersoft: this is what Arcade OSD says. Also I’m not sure if it’s relivent but it says I’m on DISPLAY4. Here are the modelines I have. Btw I have a 6450 but it says 7000 for some reason. And I nstalled the Catalyst 12.6 drivers. It’s driving me nuts... :/ Also I only seem to have 15 different resolutions after installing the ‘super’ resolution file.

[buttersoft]

The display number is not relevant, or shouldn't be. EVery time your display device (GPU) restarts (installing modelines with VMM) it iterates. When you boot the machine it will drop back to 1 or 2 again, if the GPU has two outputs. You can set MAME to target a particular display, but leaving it defaulting to "auto" is normally fine. RA IDK about, but it shouldn't be that given if you can see a picture at all, it's hitting the right display. Still, give your RA config a quick look and see?

That modelist looks normal. And when you go into those modes to test them (all except the greyed out ones) they come up looking normal, not doubled? That doesn't completely stop programs from grabbing system modes though, if you don't disable those options i mentioned before. It really looks to me like retro arch is grabbing a 480p mode that way, and sadly after the repeated advice below that's where i top out as i know very little about RA and don't use it.

Have you stopped and disabled the AMD External Events Utility service? And ticked hide modes this monitor cannot display in display properties in windows?

Just in case, have you tried the crt_emudriver based on 16.1 as well?

Consoles.

Although that's an option. A GroovyMAME user with a full set of Software List ROMs + Software List CHDs in their rompath also has access to massive amounts of content

Mame does consoles. It does lots of them very well.

[Recapnation]

The only Japanese consoles MAME "does very well" I can think of are Sega's 8 and 16-bit series (though even Mega CD is far from perfect, if I recall).



It's old, but Retro Arch's config. options were discussed here onwards:

Almost all consoles are jap. MAME does 68000 and z80 emulation near 100% perfect, so apple 1 + 2, sms/genesis, neo geo, sg-1000. Not sure how nes and snes compatibility is now with the awesome advancement lately, but I have tested Vs roms and they run fine. I’d give it a shot if your interested.

Only American consoles I can think of are Atari and Coleco, and mame is the best emu for Atari minus the Jaguar (which sucks anyways).

For avoiding split image in Retroarch :

 - Use Super resolution with this list https://forums.libretro.com/t/15-khz-crt-documentation-wiki/15671
 - In the User Modes tab in VMmaker, choose static mode and not dynamic
 - Set your desktop in 240p resolution
 - In retroarch, choose menu driver "rgui" (look in the driver menu, settings)

That's work for me

Mame does consoles. It does lots of them very well.

It also does lots of them very badly, genesis being one of them. It does however do nes and neo geo very well.

There's just way more choice when it comes to consoles with retroarch.

Hi Ex_mosquito,

The simple answer here is that RetroArch does not use dynamic modelines yet! If your setup is working with grooveymame you have probably installed the resolution in dynamic mode. You'll need to install the needed resolutions in static mode. Make sure that you edit the superres txt file add the resolutions required, make sure you check the static mode box before installing.
