EGA modes fail on real EGA card

[keenmaster486]

Title says it all. 640x200x16 and 640x350x16 modes both result in a black screen with a scrollbar and mouse cursor that you cannot do anything with. 640x350 monochrome bizarrely results in a scanrate my monitor cannot display.

Machine:
IBM 5170 PC/AT
IBM EGA with memory expansion (256KB total)
IBM 5154 Enhanced Color Display
640K RAM + 1.5MB EMS
3Com 3C509
MS-DOS 5.0

Microweb 0.53 works fine in EGA 640x350 mode. No 640x200x16 mode to try on that version.

Games that use 320x200x16 EGA modes work fine.

CGA modes still work fine.

As an aside, it would also be nice to be able to run Microweb in 320x200x16 EGA.

I made some fixes for EGA hardware but they haven't rolled into a release yet. I'll follow this up when I put up a new release to see if it tackles the issues.

I can confirm, that I ran into the same issue with my EGA laptop and MW 2.0. Modes e, f, g display this (with different resolution):

CGA works, also o for Amstrad. However, Amstrad has incorrect colors for UI elements (buttons)

And this laptop also comes with a 640x400x16 mode. There is a gra400.com to switch the command line to this resolution.
