+; 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
