1. STA $FF3F banks in RAM. (The "opposite" is STA $FF3E, which banks in ROM - default).
2. Regardless of what's banked in, you can always address the full 64K memory  ($0000-$FFFF) When ROM is banked in, $8000-$FCFF will be read only.
3. Yes, screens and charsets can go anywhere (on $0800 boundaries, so $6000 is possible, $6100 is not).
4. Not 100% sure what you're asking, but you can have either screen or charset on $6000, or even both. |
