eh? no, it's a lot of stack use to set a data seg (9000), es=scrnseg=B800 and then a default colour stored in the data ('shadow screen') seg (I need es=data seg to use "repnz stosw").

Here's the startup src code:

mov ax,0xB800 ; not a good clr
push ax ; B800
mov ah,0x90 ; for minefield seg
push ax ; to ds later
push ax ;
pop es ; ensure 'stos' to mfld [5]
mov cx,screen_size ;
mov ah,ClrBase ;segnum? nope too low ; border clr 90 no good
cwd ; clr dx as flag
repnz stosw ; cx=0
pop ds ; ds: to mfld from now on
pop es ; ensure 'stosb' to scrn

Ok 256 bytes (255 actually)
Can only mark/unmark with Space key, very poor mine placement RNG, I can only get 2 out of 3 good colours schemes on exit, so Escape shows black dashes on a brown background where the mines are.

uses LU for toggling marked location #->!->?->#,
Colo(u)r version in 256
Numbers are coloured by erm the number amount (so 1 is blue, 2 is green etc)

There's a known bug that if one incorrectly make marks (space toggle) mines in open space, then the clear rtn will show them as numbers. fixing this is 2 bytes, but 2 too many!

Colo(u)r version in 256
Numbers are coloured by erm the number amount (so 1 is blue, 2 is green etc)
There's a known bug that if one incorrectly make marks (space toggle) mines in open space, then the clear rtn will show them as numbers. fixing this is 2 bytes, but 2 too many!
"Fixed" but only by allowing toggle on any square.

std csr move L,R,U,D from int 16, cls from int 10.
Space key to mark as mine (red "!") again for (black) "?", toggle any char to Unknown (black '#')
Number of neighboring mines shown as coloured number.
Enter key to tread on square.
Win shows red '!' for mines,
Lose shows purple '*' for mine: cyan blue 'X' for marking as a mine incorrectly.
Escape key shows mine locations as black '-' on brown; can't have everything!

I'll shutup now.
