Ein Pi3 ist super zum Emulieren alter Systeme und reicht aktuell für Systeme bis hin zur PSX. Neuere Systeme kann man sich lieber billig bei Ebay kaufen. Dafür ist eine 35€ Platine einfach nicht ausgelegt.

Mit den richtigen Settings in Retroarch kann man die PSX Geschwindigkeit schon um einiges erhöhen. Input lags kann man auch ein wenig reduzieren. Das größte Lag wird sicherlich noch durch das Upscaling geschaffen. Daher versuche ich gerade alles über Scart an die Röhre zu bekommen. Spart zusätzlich auch Rechenleistung für Shader.

Hallo zusammen,

auch wenn ich mich ein wenig spät vorstelle...

Wie seit ihr zu recalbox gekommen?
Google gefragt, was besser ist als RetroPie

Wer seid ihr?
Männlich, Bj. 84

Was macht ihr beruflich?
'nen langweiligen Bürojob und freiberuflich fotografieren

Warum seid ihr Retrogaming Fans?
Warum schaut man heute noch die Simpsons? Einfach ein Teil der Kindheit und Jugend. Man ist irgendwie damit aufgewachsen und froh, das weiterhin erleben zu können (auch wenn früher gerne mal das Gamepad geflogen ist vor Wut)

Seid ihr Profis, oder Anfänger, wenn es um RPIs geht?
Mit RPIs kenne ich mich eigentlich wenig aus, aber wenn ich irgendwas machen will bekomme ich das auch hin. Ansonsten werden halt D**ke Bücher gelesen und gelernt. Egal ob Musik, einfache Programmierung, 3D modeling, Fotografie oder seine Instrumente selbst bauen. Ich lasse nicht locker bevor ich wirklich zufrieden bin (und das ist selten).

Ich überlege gerade, was man für 800-1200€ alles als Original bekommt

Hi. was the rom a .ecm file before? So you have to convert it with a special converter. Only renaming will not be successful. The other thing I would try is another bios file. For psx there are 3 different bios (us, eu and jp)

@Substring oh yeah! That's so nice. Thank you very much! I've made global timings for a 1600x240 resolution and switch back to the regular resulution for displaying emulationstation. So I have to made separate retroarch configs for every core, but it works real nice. is not pixel perfect but without seeing any artifacts. I'm very, very happy and as a photographer I normally never really satisfied with image quality.

For every console game it's already perfect. The only thing is that some arcade titles got different resolutions and i have only core specific options. As you said recalbox have only settings per system and not per system+game. So i only have to make retroarch custom settings for each rom which has no standard resolution.

@Substring ok. i think i approximately understand the logic behind it. now i got a perfect output. a centered picture and the graphic quality is absolutely beautiful pixel by pixel.

One problem is, that Marvel vs Capcom for example is nearly a widescreen game. With 320x240 i can't get the full screen because the game got a resolution of 384x224pixels.

I've found a solution for that here but where i have to put the runcommand-onstart
and runcommand-onend scripts when i switch to retroarch? simply in the script folder?

And last but not least my config.txt if anybody needs. the timings are perfect for a Sony Trinitron KV-21X5D (of course you have to make the correct settings in retroarch. so no scaling, turn off pixel perfect, custom aspect ratio, setting offset etc.)

@Substring That's the point. It have to work with every system and every config

When my system works correctly i only copy arcade roms on the recalbox instead of tekken 3 because the mame version doesn't work on the pi. So i have to use the PSX Version.

I think i have to learn french because "a l'ecole je ne l'ai pas beaucoup appris" and try to understand.

Thanks for the support with my hdmi_timings problem.

@Substring i'm looking forward to a new beta.
if i were not a noob, i would gladly help.

@Substring it's annoying to set up (a setup tool with a test image, wich change the setting step by step would be nice. i've seen something on the pi2jamma distribution) but ok.
the picture is not really perfect

the more i try to optimize my settings the more i find projects with recalbox on crt's. so it would be really nice if recalbox get an easy setup for crt's in future (with version 4.2 or 4.3 eventually)

@Substring i thinks that is the best solution. Do you know a source which explains all parameter of hdmi_timings?

@Substring now i made the update to 4.1 unstable before i change the settings for using with a CRT. Now it Works! i have to set the overscan correctly, but that's not a big deal. When i finished, i can post the final config.txt

@funkybunch have you read my answer ?

Yes i'm pretty shure i tried this way yesterday without success but i'll try it later again.

@ian57 said in Recalbox RGB/Scart Output kein Bild:

@substring : Smallcab will perhaps lend me a Pi2scart module to make the support for recalbox. When arrived I will make some tests and write a mini howto for this module.

I look forward to hearing from you soon
