Hello, I had some scaling problems on AT2 on toshiba 430CDT. This is what I get with vexp M2 T (second image) and this is what I get without vexp (first image). On AT2.ini there is these options :

screen_mode=0         ; program screen mode:
; [0] classic view (90x40 @ 720x480) (recommended)
; [1] extended view (120x50 @ 800x600) [SVGA][*]
; [2] wide extended view (180x60 @ 1024x768) [SVGA][*]
; [3] compatibility text-mode (...)
; [4] fullscreen (90x38 @ 800x600) [SVGA]
; [5] extended fullscreen (120x47 @ 1024x768) [SVGA]

comp_text_mode=0 ; compatibility text-mode:
; [0] 80x30
; [1] 80x25
; [2] 90x30 (default) Ä¿
; [3] 90x47 Ã VESA text-mode emulation
; [4] 120x47 ÄÙ

fps_down_factor=0 ; CPU saving factor for realtime gfx presentation
; and VESA text-mode emulation:
; [0] none
; [1-10] slowdown factor (1=least, 10=most)

I tried several screen mode but only the first one and 3 works, other give me a black screen. In the 3rd mode (comp text mode) only 0 and 1 works but it’s really dirty… I tried custom SVGA mode with several configurations, but it’s like the screen mode=0 config, nothing change, I also tried to change crt register values, and text column and rows but nothing change…
