@MarcDK Schalter hinterm Batteriedeckel auf ON?

Hello Marc.
Did you finally find a solution?
I have the same problem with 8bitdo in bluetooth configuration.
I also configure it normally in ES.
If i use a usb retroflag snes controller, it works. strange.

Most of the games start with no issues, the problem is that they are unplayable because of the controls.

Must say: a lot of them are unplayable because of the controls.

@marcdk Our main contact for this is our community manager @Fab2Ris. You can contact him on discord to expose how you want to contribute. @Fab2Ris

@marcdk If you are in Linux, use gparted. If you are on Windows, you need a specific program to resize partitions, whichever one serves, one of the most popular is partition magic. Another option is to download a Linux image, burn it to a USB flash drive, make a "live CD", boot the USB stick without installing Linux (there is an option to test the system without installing it on the PC), and use gparted .

@marcdk yes, it can.

@lee-mcnutt I do not know what it can be, I do not use this, I use ARRM and I have no problems, if you need support for the skraper, use the specific topic:

@marcdk you don’t need permission to create it, just do it 😉

@marcdk Dude, I know you can probably guess by yourself that:

we are not Retroarch pros some settings could have been written AFTER recalbox was started we can't keep an eye on every Retroarch commit + every libretro core commit + every emulator commit + every buildroot commit just regarding dispmanx, I'm the one who added it on 4.1 we terribly lack time and/or contributors to do this ground work and yes, we also aim for the "most compatible" configuration in terms of emulation but also arch (pi, odroids anx both x86 share the same RA configuration file)

We're really open to get feedback from users if they are willing to improve anything. But just read our commit log, just check by yourself : hardly any one does.

Now a little earlier in the conversation you asked

So please tell me how to significantly reduce the input lag on recalbox with a raspberry pi. I will measure it and extend the article right away.

@joinski gave you some leads, so go ahead and try it by yourself, measure it, write blog articles if it's your hobby. We both know it will never reach the latency of a modern computer or a dedicated box. But it can be slightly improved, maybe to a point where you can feel "more comfortable" when playing, without ever reaching what a PC can do. Regarding PC, i also remember that some libretro forum member made some measure and sad a windows PC was around 7 FPS of input lag, linux was 1 FPS above.

The input lag investigation says it all, is very complete regarding tests, the way they did it etc ...

Retropie gives a few tricks, despite i'm sceptical about the video max swap chain, i was told to put it to 2 or even 1 by libretro members.

@marcdk

Schöner Test! Sowas wollte ich auch schon immer mal machen (aber dann mit PS3 Controllern per Bluetooth mit entsprechendem USB-Dongle und dann einmal nen PC mit recalbox vs. Pi3 mit recalbox), bin nur zeitlich bisher noch nicht dazu gekommen.
Diese 240fps-Aufnahme sollte doch aber auch schon mit nem iPhone 6 oder 6S gehen oder nicht?

Wie man an deinem Test sehr schön sieht, wird der größte Teil des Input-Lags durch die Emulation erzeugt. Danach kommt erst der TV/Monitor (wobei es da ja auch leider einige TVs mit nem sehr hohen Input Lag >50ms gibt, trotz Einschalten des Game-Mode am TV bzw. Ausschalten aller Bildverbesserer) und danach die Art und Verbindung der Controller.
Am Ende summiert sich das alles zusammen und man fühlt den Unterschied beim Spielen schon ab einer Differenz von >50ms teilweise deutlich.

Also meiner persönlichen Empfindung nach spielt es sich mit einem Gesamt-Input Lag (Bildschirm + ggf. Emulation + Controller) von <30ms sehr angenehm, <50ms noch ok und ab >70ms wird es unangenehm.

Alles größer als 100ms wird dann schon echt ziemlich laggy und man muss sich umgewöhnen (bei Mario früher abspringen als normal).
Wenn man sich sehr lange an einen größeren Input Lag gewöhnt hat, ist es dann auch ziemlich komisch, wenn man z.B. wieder vor einem original Super Nintendo sitzt. Aber man gewöhnt sich an den sehr niedrigen Input lag dann wieder schneller, als es gebraucht hat, sich an den hohen Lag zu gewöhnen.

Bei Spielen wie z.B. Tetris verliert man bei zu hohem Input Lag (>100ms) aber definitiv den Spiel-Spaß und man schafft auch keinen so hohen Highscore wie mit niedrigerem Input lag.

Ich hab es wie gesagt bisher noch nicht so richtig verglichen (also z.B. nicht mit der Methode der Slo-Motion Aufnahme über ein iPhone bspw.), aber gefühlt würde ich sagen, gibt es keinen großen Unterschied zwischen nem Pi3 und nem PC (beides mit PS3-Controller per Bluetooth und gleichem Bluetooth-Dongle + der aktuellsten Recalbox-Version, PC Hardware = Intel NUC-Kit D54250WYK mit i5-4250U). Am PC ist es vielleicht minimal besser, aber ich werde das bei Gelegenheit mal genauer vergleichen. Am meisten fällt mir der Lag wirklich bei Spielen wie Tetris (Gameboy) oder Tetris & Dr. Mario (SNES) auf.

@voljega said in bug report: Dreamcast (Reicast) hotkey exists directly the game:

@eb2016 not all of them and because the ones which have that feature are libretro cores, but reicast isn't.

Indeed 95% of systems are emulated with retroarch which has the combo hotkey+keys sortcuts feature.
Other systems are emulated by standalone emulator which in most of the cases don't have this feature.
In the best case we can map a gamepad button to exit, but often we can't and the only way to do it using a keyboard...
Si that needs to patch, rewrite the source code of each emulator (if possible) to manage the hotkey feature.
That requires, programming skills, time, tests and time.

I have the same issue with a fresh installation of the latest Recalbox from today. The settings were not saved, the SD Card storage is "n/a" and my XBOX controller isn't working either.

Is available now. Thanks. But I got some errors I have reported in a new thread.

@marcdk I think no one among the team will ever work on such a feature. Otherwise just make an overlay for retroarch by yourself, and set your shortcut in that overlay + edit retroarch config file to use that overlay.

@marcdk Now I understand: The raspberry Pi is stuck with an old MAME version. For everyone who comes here because of google:

https://docs.google.com/spreadsheets/d/12tEAwM76WmxIzEpGBovco9JLraqjyK1lJ6azosCtF-8/edit#gid=1761315220

That is a compatibility list for MAME in Recalbox and these games I mentioned are not supported.

@substring said in Glitches and slow performance with Odroid XU4Q (with video):

Oh my God you are just terribly wrong ... Compare what can be compared. Run DC at 1080p on a pi3 if you want to oppose it to a XU4, so that both boards are compared in the same conditions ... Compare PSP for example, like Kingdom Hearts ...

I get your point and yes I see the improvement over the raspberry pi 3. But still there is not enough power to run it with 60 fps. Not even in a lower resolution. I tried that. And yes, this is not the "fault" of the odroid.
I understood that this is not going to chance in the near future because of the state of the dreamcast emulators for ARM processors.

I may try the x86 emulators. Thanks any way for your time.

@rockaddicted Ok thanks for telling me 🙂

Same to me, the settings of my Joypad don't get saved after all - same to all the other menue settings (running at a fresh install of 17.12.02 here)
