char pointer bend to another address

[boriel]

hello, good day.

why is the letter "Y" not ok?

ZX Spectrum UDGs are available only until letter "U".
If you need more graphics, you will have to use normal chars PTR, which is the 1st method I described.

I think this is already answered here in the forum somewhere (you have to set CHARS ROM var to the address of your data minus 256). This process is a bit more convoluted, if you don't have experience doing it.
