SEGA Model 2 emulator 21:9 request

[iamccwwcc]

first of all sorry for my bad english, i have a ACER X34P try to play some old arcade games like Virtua fighter 2 in 21:9 3440x1440
the emulator itself support 16:9 16:10 4:3 aspect ratio but no ultra-wide, you will get the image stretched
like this

also i found out it support LUA Scripts

Model2_SetWideScreen(int)
Enable (1) or disable (0) 3D transforms to output widescreen data

Model2_SetStretchALow(int)
Enable (1) or disable (0) stretching to all visible area of the A tilemap when set in background mode

Model2_SetStretchBLow(int)
Enable (1) or disable (0) stretching to all visible area of the B tilemap when set in background mode

Model2_SetStretchAHigh(int)
Enable (1) or disable (0) stretching to all visible area of the A tilemap when set in foreground mode

Model2_SetStretchBHigh(int)
Enable (1) or disable (0) stretching to all visible area of the B tilemap when set in foreground mode

i dont know if this helps to fix the 21:9 issue, dont know what to do
so i'm asking if anyone has experience to help, thanks

Looks like Model2_SetWideScreen(1) will do，but only in 16:9 ratio
