@lauderneto everything was done also amateurally in our side too:)
Because we don't want to put too many systems because of the limited vram of the RPI I don't think we will create new theme and so separate CPS1 CPS2 .... Today because I am visiting AirDream in Japan we worked a little together on atari5200 and we have done it(bg bg2 music) (link below) and we will work later on the not yet included system that will come in beta. By the way can you give me link where its precised about the new addons systems?
As for svg I managed to convert them through Inscape(free programs I put in the beginning of the Mukashi Theme post)
I have to say it is a bit hit and miss because I don't master at all the program but I managed not really knowing how ! But this is the program to go with with svg!
Its possible some of our logo are in png in the theme because svg was a bit complicated to find or to convert.
Because we didn't download the beta of course yet we can't test it....
It was very good, congratulations.
when I am at home I will lower and discard what I have done.
the beta system where it contains the new systems can be found at this link. https://forum.recalbox.com/topic/15010/testers-wanted-major-system-upgrade-pi3b-kodi-17-and-much-more
I'm using it as main and it's working normally.
in my case as I use the raspberry pi3b +, I am limited to using systems like WII, 3DO, PSP and others that do not run. so I do not think I will have problems with VRAM because I do not use those systems.
I'm still thinking of neither using computer games like atari st, atari 800, commodore 64, amistrad cpc.
The only thing I think of using is my friend, because it was part of my life. :)
I also think about putting the Super Nintendo MSU-1.
