;
; character set for use with the soft80 implementation
;
; the format of the data follows the following layout:
;
; - to avoid unnecessary petscii->screencode conversions, the order of the
; individual characters is different to the C64 ROM charset:
; - $00 - $1f screencodes $60 - $7f (petscii codes $a0 - $bf)
; - $20 - $3f screencodes $20 - $3f (petscii codes $20 - $3f)
; - $40 - $5f screencodes $00 - $1f (petscii codes $40 - $5f)
; - $60 - $7f screencodes $40 - $5f (petscii codes $60 - $7f)
; - only 128 characters are defined here, the soft80 implementation will invert
; the graphics data for inverted display on the fly.
; - finally the lower 4bits are "inverted", ie a space character is represented
; as $0f, $0f, $0f, $0f, $0f, $0f, $0f, $0f
;
; the graphics data is arranged differently to normal C64 charsets for speed,
; first comes the first row of all characters, then the second row in the next
; block, etc. like this:
;
; +000 ....xxxx ......xx ....xxxx ........
; +080 ....xxxx ......xx ....xxxx ....xxxx
; +100 ....xxxx ......xx ....xxxx ....xxxx
; +180 ....x..x ......xx ....xxxx ....xxxx
; +200 ....x..x ......xx ........ ....xxxx
; +280 ....xxxx ......xx ........ ....xxxx
; +300 ....xxxx ......xx ........ ....xxxx
; +380 ....xxxx ......xx ........ ....xxxx
