Bug ES2 with Dgen 1.33

[ian57]

Hi Aloshi, thanks for your amazing software, it helps me to build my own arcade distro on Pi here https://sourceforge.net/projects/raspicade/

Actually I have an issue using ES2 (stable and unstable from github) with Dgen 1.33 (last release)

When quitting a game from Dgen, Raspicade freezes... with the error (dmesg command) :

This issue does not appear with Picodrive with ES2, or using Dgen 1.33 with ES1.

Thanks again for your amazing work

does the emulationstation applications output provide anything

[ian57]

In fact raspicade does not freeze I can work through ssh, only ES2 graphical gui is freezing. Will check the log...

why/how are your gamelist in your roms folder and not in ~/.emulationstation/gamelists/$SYSTEM/gamelist.xml

[GM-Script-Writer-62850]

are you sure the emulator is exiting?

[ian57]

Because I use them with ES1 too. Will check for the emu

Dgen is quitting when using it in console mode. but When quitting ES2 to console I need to type CTRL-C to get the console... seems to be stuck on something

[Aloshi]

Another thing to check: are you sure your version of the Raspberry Pi firmware is up-to-date? This sounds like a problem with DGen or maybe even SDL2, which is unfortunately not something ES can fix.

[ian57]

Ok thanks, I've done that yesterday and I had another problem (last kernel 3.12.33+ + firmware), with the joystick configurator. When pressing joystick button to configure, the configuration window appreared behind the very first windows asking for pressing to configure. The configuration works, but I needed to make it in "blind".

I recompiled SDL 2.01, and after last release of ES2 (from git pull) with the new firmware, It seems to fix the the "configuration problem". I did not already test this with DGEN. Will make a try and let you know. Another question : when getting back to ES2 from a game, the time is longer than ES1 and we have the "console view" with linux text, is it possible to have the black screen with the white point to mask this? Again thanks for your amazing software.

[GM-Script-Writer-62850]

in the part where you have ES startup run the clear command before starting ES and start es like this clear;emulationstation > /dev/null 2>&1 all output will be nullified making debugging it very hard, but ti will leaves solid black screen when you start/exit a emulator on retropie i believe es is started from /etc/.profile on the last list, might be ~/.bashrc

[ian57]

Thanks a lot for the tip. Will try that quickly. But most of the time, the console text comes from the emulators themselves... Will make that to emulators run commands too.

Hi,

The compilation of SDL 2.01, and after last release of ES2 (from git pull) with the new firmware fix the config program problem I had.

This manipulation fixes the DGEN problem too. Thanks a lot.

The tip given by GM-Script-Writer-62850 is working quite good. I added my quiet mode to this and it is now perfect, no more text on my console during the way back to ES quitting a game, no blincking ...

to get ultra quiet boot add this line in cmdline.txt... now linux boot log are send to tty2 and you're watching tty1 :)
