85a53f89c8 Start implementation of display emulation. 
Something like a character RAM for a start. When 65C02 writes into
this space, a callback will be executed that would allow redrawing
the emulated screen. Multiple backends can be supported this way.

c23136800a Unbreak BBR and BBS - they access zero page, don't act like immediate. 2017-02-13 18:39:51 +01:00
Radosław Kujawa
8de5574aab Handle accessing bus in zero page relative mode just as in zero page. 
It should make things less awkward and still work fine, as the only
instructions using this mode are BBS and BBR. These only use first
operand as the address in zero page to read data from.
