If the word isn't very long, say 8 character of 8x8... you could of course 'plot' the word using inverted black sprites, then you can have any background you want.
If you use MSXBAS2ROM compiler you can write a program just like that to do it:
10 SCREEN 1
20 PRINT "CHANGING THE LETTER A"
30 SET TILE PATTERN 65, (,,,,,,,255)
40 A$ = INPUT$(1)
50 SET TILE COLOR 65, 4, 8
60 A$ = INPUT$(1)
70 SCREEN 0
Line 30 modify the pixels of the 8th line of the character 65 (draw a line below it), and line 50 modify the fore/back colors of the characters around 65.
If you change the line 10 to "SCREEN 2 : SET TILE ON", the fore/back colors will affect only the character specified.
There is a problem now: After my BASIC-Prg was finished and saved on a virtual disc image in openMSX and I load it again, half of the code at the end was missed. I wrote it again save and load and it was the same... I used another disc image and a other virtual MSX in OpenMSX - same. I make an upgrade from 16 to openMSX17, but the same... What can this be? I use openMSX in Manjaro.
