FIXED!!! thanks to toniosj, see the gitlab link at the beginning of this post.. but essentially it's due to my 4K tv and he had me change some setting in config.txt, so visit the gitlab issue for specifics
Edit your "config.txt" file on /boot folder:
-If you're using PuTTy use "mount -o remount,rw /boot" commmand.
-If you're using WinSCP open console (Ctrl + T), enter command "mount -o remount,rw /boot" and click Execute.
From this file search for hdmi_group and hdmi_mode and set both as following :
Don't forget to remove '#' char on those lines if present.
Not load of the system in background here 😕 . Right now I checked it again several times with same result. As example in the next case, if I set a custom video in folder bootvideos with this configuration in recalbox.conf
The system is delayed 30 seconds more in startup. The spashscreen with pacman and the load of emulationstation appears after the video is played.
As another option more:
If there doesn't seem to be a good solution soon, take into consideration to add optionally the core dosbox-X. It is a more advanced and vitaminate version of dosbox. https://dosbox-x.com/
@abis1979 Possibly your computer is so new that there is still no integrated driver to Recalbox. Try a clean installation of the latest version of Recalbox, both the 32-bit version and the 64-bit version, if none works, you'll probably have to wait for an updated version of the system ...
Usually the incompatibility happens with the video card driver, but I can not say that's it.
I could easily upgrade by getting motherboard with Atom D525 / ION2 or Atom D2550 / GT610 installed. Makes sense?
It would be the same issue, as i said if you want to play PSX and don't want to use an arm cpu, you'll need a cpu @ 2.4Ghz as a minimum. If you don't plan to play something "higher" than psx, you should use a raspberry.
Unfortunately, not all devices are compatible with Recalbox. you did not say which version and what architecture you tested, by the configuration of your computer I deduce that you have tried to install the 32-bit version, considering this, TEST the 64-bit version also (or vice-versa) it is not a guarantee, but it is better to test.
If the other version does not work, it is a sign that there is a driver incompatibility, probably with the video card (this has happened to me too, there is nothing to do for now).
They are testing a version, it is in the open beta phase, it promises to bring several improvements and greater compatibility, it is a possible future solution.
Simple overclock of the cpu is not enough to handle the dreamcast.
With some custom overclock settings I managed to run Virtua Tennis 2 around 90-95% of its full speed with very few minor glitchs. So the game is playable and enjoyable.
A lot of games are close to work at full speed, if only the pi3 have had a bit more cpu speed.
Every pi are different, so if it crashes or displays a black screen, you must lower some values (see the range in my config.txt below).
WARNING: you REALLY need a good cooling setup (fan + heatsinks) if you don't want to grill your pi.
My settings works for me and my pi3 can stay on for hours, BUT I can not be held responsible if your pi goes down.
In config.txt of the sdcard (plug it in your computer), here are my settings:
