GBA + vga_scaler on NTSC Television issues

[mukiex]

The GBA section in my MiSTer.ini looks like this:

Code: Select all

[GBA]
vga_scaler=1
vscale_mode=0
ypbpr=1
composite_sync=1
;video_mode=320,16,30,34,240,2,3,22
video_mode=320,8,32,24,240,4,3,16,6048
;video_mode=320,10,20,54,240,6,8,10,6400
;video_mode=320,16,30,34,240,2,3,22,6400

I've tried all of the modes listed but commented out up there, in hopes of getting a full-screen GBA experience, but like, halfway into the GBA startup animation, the resolution instantly changes into some crazy resolution that my CRT Television cannot display.

Using the same modes on the main MiSTer menu works just fine (albeit with a very wide MiSTer menu image). I'm not sure what's happening on the GBA that basically overrides the VGA scaler. It also happens regardless of whether I have the above ypbr=1, composite_sync=1 and vscale_mode=0 settings present or not.

edit: Also happens whether on Homebrew or original BIOS. Also tried forced_scandoubler=0, to no avail.

You probably have video_mode_ntsc set in your ini so you need to add that to GBA section with the same settings too.

Code: Select all

video_mode_ntsc=320,8,32,24,240,4,3,16,6048
