The Problem:
On some video cards, Ultima I doesn't display properly in its default EGA mode. The graphics go black-and-white and eventually get garbled. This problem is caused by a bug in the 'out.exe' file.

The Solution:
First, rename your 'out.exe' file 'oldout.exe' or something similar. Then copy 'newout.exe' to 'out.exe'. For example,

ren out.exe oldout.exe

copy newout.exe out.exe

When you run Ultima 1 now, the EGA graphics should be fine. I haven't tested the patch on video cards other than my own, so I don't know if it always works. If it causes problems for you, you should restore your old 'out.exe' file.
