Gameboy Zero HDMI-TFT problem

Hello Guys ,
I have already finished my Raspberry Zero (Gameboy Project with Retropie). I just want to add a kind of switch ... so i can use HDMI TV and TFT screen. Ok some changes in
config.txtand it was done but my main problem now:
I had to rotate my TFT screen about 180° to build it in properly, my problem is now that in
config.txti have to use :
so my TFT Screen shows on boot correctly, now putting in my HDMi-cable it shows obviously the 180° rotated framebuffer.
i can't use
display_lcd_rotatebecause i dont use GPIO as i said and i also can not add
display_hdmi_rotate=0because it just overwrites
display_rotate=2... so now my TFT is shifted wrong but the TV correctly ...such a dumb fail but thats how it is.
I just read about copying the
config.txt, change one of them for HDMi and one for TFT and select over a small script the correct one for the current boot option, but i dont know how to set this up. Ty guys, hope u can help me!
