@substring No problem. I prefer not to have sound before ES anyways.
Thanks again for all the help.

@psykoknarf Hi,

You cannot use both TFT and HDMI screens.

@tikiandskull ou on m'en a parlé sur IRC, je ne sais plus ... Mais je sais que j'ai déjà vu le truc, oui

J'ai pensé à une autre solution plus stable : utiliser une carte Teensy ( ou autre ?) avec le joystick analogique connecté, soit à l'USB du RPI, soit en SPI .
Avez vous déjà testé?

Hello

read theses links to begin :

@Seramis Hi !
First of all, I summon @ian57 as he is the one who knows most abt screens. But it seems to me this one is connected on the SPI, soe you'll get a very poor performance on it as the FPS is really low on it.

concerning the switch between hdmi output or "any other video output", i'm not so sure ... Let's say that i've only found hacks to do that, but no easy process. I've found some interesting doc from raspberry for some "multi monitor definition", but i'm afraid it won't be enough

@lackyluuk, in 4.1 RB is prepared for waveshare 3.2 and 3.5 support (overlays and config in recalbox.conf) using fbcp program. It is really easy to make these

Geekwrom HD 3.5 Inch TFT Display Shield 800x480 is also supported see wiki page here https://github.com/recalbox/recalbox-os/wiki/Mini-How-To-(EN) in audio video section

@pati disable it time to test your device, at least :)

A oui c'est surement ça, je ne savais ce que c'était l'overscan..

je vais suivre le wiki, merci à vous pour les infos :) je mettrais une photo de la gameboy une fois terminé ;)

Oki je vais faire ca !! Merci!

Any luck getting this to work? Got an old Gameboy that needs hacking...
