I asked about the language because if you use redefined charsets in BASIC you have to "protect" that memory range so it doesn't get overwritten by variables etc. Therefore, it's best to place the charset at the start or at the end of the BASIC memory.
I have never used Graphics Master but setting a redefined charset is a somewhat trivial task and usually done like this:
POKE 65298,PEEK(65298)AND251: POKE 65299,DEC("HI")
HI=Highbyte of the memory location, hexadecimal value. Of course this can be POKEd as decimal values, too. But this way, it's more obvious ;)
I just checked out Graphics Master. It uses $3800- (which is at the end of the RAM on C16s) for the redefined charset.
Try loading the saved charset...
LOAD"CHARSET",8,1
then enter
POKE 65298,PEEK(65298)AND251: POKE 65299,DEC("38")
Now you should see "your" charset when you press the keys you redefined.
When you cause an ERROR now, the screen looks garbled. That's normal (due to a faulty routine).
Switching back to the ROM charset can be done by entering these POKEs:
POKE 65298,PEEK(65298)OR4: POKE 65299,208
Just try if the above works for you. We'll take care of the rest then...
