Lindbergh change resolution Primeval Hunt

[Marcosagud]

Hi, i am new, i have Red Lindbergh arcade, Primeval Hunt standar with CRt monitor VGA. I have replaced for a 32 hd lcd monitor. I tested switch to increase resolution, but aways except vga gives 51 error. I can only access bios but i think need to change any parameter on Linux vga=311 tp 317 i think. Any idea or is imposible to setup. Thanks in advance.
Regards.

The game executable, in this case Primeval Hunt, is what sets the resolution itself when it starts. To change the resolution you need to find & patch the value in the game.

Some of the teknoparrot roms have modified resolutions, so comparing those would likely point you to where you need to look.
