 Re: Screwed up charsets

It is possible that the charset was placed at some position of the memory that gets screwed up during a reset. If the development was done using tedmon it usually has to survive several resets.

Just from memory, those places get messed up during reset:

- $7ffx ($7ffe?) memory bank number is written into this position when kernel initialized custom roms

- $3058-$305f - $28, ff is written into two bytes. I never figured out why. But this would correspons to a "K" in a charset that starts at $3000. Quite possible that also $304x gets messed up in a similar way ("I")
