Switchres: modeline generator engine

[Calamity]

===============================
Update 5-10-2014 - Version 1.52
===============================

- Added new option --edid. This option creates an EDID binary file (edid.bin)
  based on the calculated modeline and the monitor ranges used in its
  calculation. This file can be passed to the Linux kernel on boot in order to
  enable the same user defined timings for both KMS and Xorg.

So i'm just trying to understand some of this resolution/modeline/Hz/etc stuff
I have a question though..
Galaga natively runs at: 288 x 224 (V) 60.606061 Hz
But Switchres chooses: 2560 x 288p 51.774 Hz 16.050 KHz

But if i press F11 during gameplay it says it's running at 100%

How does this work if it's running at 51.774Hz instead of 60 Hz ? Is it running at it's correct speed or not?

Obviously the refresh is not correct (it can't be on a standard arcade monitor). But the speed is, because we detach the emulation from the refresh. This is achieved by triple buffering (multithreading must be enabled for this). GM enables triple buffering automatically when it judges the target refresh is going to be too off, being the default threshold 2.0 Hz. You can modify this value through the -syncrefresh_tolerance option in mame.ini.

I fixed some bad bugs (related to memory allocation).
You can find the updated version here.

Hello,
I am new to this forum and I hope to write in the right section.

I have some problem with Groovymame and Switchres.

I state that I disabled in MAME.INI interlaced resolutions because they do not love them.

With the desktop resolution to 640x480, and Groovymame Swithchres working properly.

If instead you imposed the desktop resolution to 640x240 and Groovymame Swithchres only work for a few games.

Rampage games by type, Paperboy, 19xx, Twincobra, maintains it in exchange for a resolution.

For other types Metalslug, Rolling Thunder, Pacman (Midway) work perfectly.
Some idea?

Use CRTEmudriver 6.5, ATI x300, Groovymame 0148u5.014b and WindowsXP.

Thank you.

Hi

Coming from here. Groovymame creates a good modeline for sega genesis but standalone switchres doesn't. I gues groovyarcade's switchres comes from this 4 year old git repository, so it may be the problem.
https://github.com/Ansa89/switchres

I've found a newer repository here.
https://github.com/antonioginer/switchres

So cloned it and tried to compile for testing, but I get dependency errors... (SDL_syswm.h). That's strange because I've compiled MAME with groovymame patch in this machine with no problem. Any help for compiling? I'm using debian, but can try from arch.

[Calamity]

Are compiling the branch named "standalone" right? Make sure you checkout this one instead of master.

[ronbin]

I was compiling master...

Cloned standalone branch but now I have another error

If you're having troubles, you can try the automatic builds here: https://github.com/antonioginer/switchres/actions/runs/88479738

[ronbin]

Thanks Calamity. I could compile it from groovyarcade, there must be something wrong with my debian setup...
It seems new switchres has different options, I will do some tests tonight.

Thanks again!

This new switchres version doesn't support the --emulator and --rom switches. You should use -l '<full command>'

[ronbin]

This worked perfectly.

Code: [Select]

switchres_main -s 352 240 60 -i mame.ini -l "mednafen /home/roms/Saturn_roms/romname.cue"
switchres_main -s 320 240 60 -i mame.ini -l "mednafen /home/roms/Saturn_roms/romname.cue"
Now I can run saturn games at 704x480 or 640x480 resolution with scanlines. It's a shame I can't know game's resolution before loading it... but that's not switchres' fault.

Thank you for your GREAT work Calamity.

It's a shame I can't know game's resolution before loading it...

That's why I've removed consoles. Whe you play on a CRT, you want some serious business, NTSC vs PAL refresh rates, not some "let's set 230x240 once for all, emulators will adapt".

But things may change ^^

[DaddyLongLegs]

Should switchres be doing anything to 640x480 images on my standard def Wells Gardner?

I know with lower-res stuff I'm used to seeing a huge horizontal number and the same vertical number but my 640x480 games look like this:



Should the horizontal number be different? Or is that only for lower resolutions?

Also is switchres changing the Hz from 54.124000 Hz to 57.000 hz the reason this particular game runs way too fast? If so, is there any way to fix it?

Hi. I'd like to test the latest standalone build for win32 x86_64 but the automatic builds are all expired and I had no luck compiling it. Anyone can post it, please?
Thank you.

Very Thank you, Calamity!
