106 First stable version. Things seems to be working. Simulation is currently at 20%. gabrieloshiro 5867d 23h /t6507lp/trunk/
105 The RTI instruction is working fine. Coded and simulated. creep 5867d 23h /t6507lp/trunk/
104 The BRK instruction is working. The reset vector was tested also. creep 5868d 01h /t6507lp/trunk/
103 Some early modifications to support the special stack instructions. creep 5868d 19h /t6507lp/trunk/
102 Some early modifications to support the special stack instructions. creep 5868d 22h /t6507lp/trunk/
101 Absolute indirect addressing mode is coded and simulated. creep 5869d 01h /t6507lp/trunk/
100 IDY WRITE TYPE instructions are coded and simulated. creep 5869d 02h /t6507lp/trunk/
99 Only Package.v should be used. creep 5869d 03h /t6507lp/trunk/
98 Updated status and some comments. creep 5869d 03h /t6507lp/trunk/
97 Removed obsolete TODO. creep 5869d 03h /t6507lp/trunk/
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5871d 18h /t6507lp/trunk/
95 IDX addressing mode is also 100%, coded and simulated. creep 5871d 22h /t6507lp/trunk/
94 Relative addressing mode is almost 100% functional.
It just needs another test to check if the adrres_plus_index logic is not recalculating the pc in two consecutive cycles.		 creep 5872d 18h /t6507lp/trunk/
93 Opcode for BNE was wrong. creep 5872d 20h /t6507lp/trunk/
92 Absolute indexed mode working properly. All cases were simulated. creep 5873d 01h /t6507lp/trunk/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5873d 01h /t6507lp/trunk/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5873d 01h /t6507lp/trunk/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5873d 02h /t6507lp/trunk/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5873d 02h /t6507lp/trunk/
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5873d 18h /t6507lp/trunk/
