CIRCUITOUS font information
|
|
2019-07 last updated
|
|
|
|
- $80 characters only (high bit is always 0)
|
|
- $20 and above are standard ASCII
|
|
- $00..$1F are various shapes and characters in no standard order
|
|
- Capital letters are full-width, which makes all-caps drawing look bad, so
|
|
don't do that
|
|
|
|
Font routines are near the top of LC RAM, accessible to either bank. However,
|
|
font data is stored in LC RAM bank 2, because that's where we have space. Note
|
|
that most strings are in LC RAM bank 1, which is admittedly inconvenient. You
|
|
are responsible for copying characters to a place where the drawing routine can
|
|
access them. (See src/ui.font.a) The drawing routines will switch to LC 2 to
|
|
access font data, then back to LC 1 before returning.
|
|
|
|
Font data is stored non-consecutively. Row 0 data starts at $D600, in order, so
|
|
row 0 of character $00 is at $D600, row 0 of character $01 is at $D601, &c.
|
|
Row 1 starts at $D680; row 2 starts at $D700. The entire font set finishes at
|
|
$D9FF.
