: (5) EGA/VGA specific: support for DR-FONTS
: (thanks to John Elliott, who submitted the changes)
This is broken :-(
- You've missed a line in the bit that skips over fonts of unknown size.
EGAR.ASM lines 316-321 should read:
mov ah,al
xor al,al
add ax,6
add si,ax ; <-- this line is missing
clc
ret
- In ReadSubs at line 397, there's a
jc ReadCodepageError
which I think may need to be
jc ReadCodepageDisplayError
- Something horrible happens to the first codepage loaded the second time
it is selected. For example:
MODE CON CP PREPARE=((437,850) EGA.CPX)
MODE CON CP SELECT=437
MODE CON CP SELECT=850
MODE CON CP SELECT=437
The second time CP437 is selected, the video font will be replaced with
random data. If I swap the order over:
MODE CON CP PREPARE=((850,437) EGA.CPX)
MODE CON CP SELECT=850
MODE CON CP SELECT=437
MODE CON CP SELECT=850
then it's CP850 that gets corrupted, and CP437 remains untouched.
