Retroflag GPi Case / GPiMate+ / CM4 lite

[TiFab77]

Hi all,

I just received my GPi Mate + and my CM4

the CM4 is the lite 4GB + WiFi/BT

up to know I managed to install Retropie from the image provided here
I took the Pi4/Pi400 version

I managed to put it on my WiFi and to fix ES orientation but boot messages and retropie splash are rotated 90° anticlockwise
I managed to get dpad works and most of the button.
I have issue with start and select ones

Here is the config I use : (es_input.cg in ~/.emulationstation/

<?xml version="1.0"?>
<inputList>
    <inputConfig type="joystick" deviceName="Xbox 360 Controller" deviceGUID="030000005e0400008e02000014010000" deviceNbAxes="4" deviceNbHats="1" deviceNbButtons="13">
        <input name="b" type="button" id="1" value="1" code="304" />
        <input name="a" type="button" id="0" value="1" code="305" />
        <input name="down" type="hat" id="0" value="4" code="16" />
        <input name="hotkey" type="button" id="8" value="1" code="314" />
        <input name="left" type="hat" id="0" value="8" code="16" />
        <input name="pagedown" type="button" id="5" value="1" code="311" />
        <input name="pageup" type="button" id="4" value="1" code="310" />
        <input name="right" type="hat" id="0" value="2" code="16" />
        <input name="select" type="button" id="8" value="1" code="314" />
        <input name="start" type="button" id="9" value="1" code="315" />
        <input name="up" type="hat" id="0" value="1" code="16" />
        <input name="y" type="button" id="3" value="1" code="307" />
        <input name="x" type="button" id="2" value="1" code="308" />
    </inputConfig>
</inputList>

I also tried to launch some games their aspect is streched on the width

I followed this howto :
link text

But I changed some parts due to impossibility to display
I also added the files "dpi-pizero-gpicase.dtbo" & "dpi-pizero-gpicase.dts" from my recalbox Pi zero cartridge
