uli New version of Bescii! (v1.2)
http://damianvila.com/bescii/bescii.ttf
I mapped all the PUA characters to the PETSCII reference. Both your mappings and Tamakichi-san's mappings should be there (I checked, but if you see something missing, let me know.)
I also mapped the Amstrad characters you have mapped to 0x20 to the following code points:
[0xef] = 0xefef, (rocket symbol)
[0xfc] = 0xeffc, (bomb symbol)
[0xfd] = 0xeffd, (wtf? > cloud with lightning symbol)
I'll include the same mapping in the Amstrad font, but I'll update that later, since I want to expand it to support more languages.
And I modified a couple pixel art characters, and added a few more (they're remapped to f000-f067):
Let me know what you think.
