First of all, my batocera 5.25 works under a CRT 15KHz (50Hz (pal) not 60Hz).
And I know these two posts
it was my post 1 month ago … I gave all my system ans i explain the way to work
ATI Radeon X600 256MB.
intel® Core™2 duo cpu E4700 @2.6GHz
xrandr -s 640×480 doesn’t work for CRT 15KHz for sure …. this is for 60Hz vga
The command in .xinitrc who work for most emulators under batocera is :
In .xinitrc, you must put
xrandr –newmode “648×480_15KHz_50Hz” 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace
xrandr –addmode DVI-0 “648×480_15KHz_50Hz”
xrandr –output DVI-0 –mode “648×480_15KHz_50Hz”
Here is a example of pal modeline 50Hz 15KHz. it can be changed by other modeline
I wrote two codes for that. One for verify an modeline and another one for calculated a modeline with the resolution, the V H blanking (front and back porch), the pixel clock, the V H sync, the framerate (interlac or not) and the parameters for moving picture.
The only question is why batocera works for lots of systems but not for FS-UAE amiga and why it’s work Libretro PUAE.
