- Log message:
- *** EMERGENCY BUGFIX ***
- Signal rd_o was corrupted in last version. wr_o and wr_n are not effected.
- OP "JMP (indirect)" produced a 65C02 like jump. On 6502 a special case exist
when the (indirect) address cross the page boundary (e.g. JMP (02FF) reads from
$02FF and $0200, instead $02FF and $0300)
