2015-01-01Remove some of the hard coded assumptions about the memory map from the CPU ↵Michael Pavone
cores
2014-12-30MergeMichael Pavone
2014-12-29Fix handling of code writes for Z80 core. This seems to get things close to ↵Michael Pavone
being back to where they were before the big refactor that broke the Z80 core. Some problems remain. Notably the sound driver in Sonic 2 is still quite broken.
2014-12-26Fix a few bugs introduced in the Z80 core from the adjustments to fit with ↵Michael Pavone
the code gen refactor
2014-12-26Fix an off-by-one error in a branch destination in the generation of ↵Michael Pavone
handle_cycle_limit for the Z80
2014-12-26Update code->cur before calling z80_get_address_trans in ↵Michael Pavone
z80_retranslate_inst to avoid any newly translated instructions from being placed in the "buffer zone". Save the current value of the code_info struct for placing the final jmp instruction in the correct place
2014-12-26Add in missing generated Z80 helper functions. Fix a small bug in Z80_HALT. ↵Michael Pavone
Fix generation of save and load context for Z80
2014-12-22Z80 core is sort of working againMichael Pavone
2014-12-17Get rest of emulator compiling again with Z80 core enabledMichael Pavone
2014-12-17Get Z80 core back into compileable stateMichael Pavone
2014-12-16Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc ↵Michael Pavone
when using IX or IY. Fix access to I and R registers (R still needs to be made 7-bit though). Fix flags for ld a, i. The fix for access to I fixes PCM playback in Titan Overdrive and music playback in Crackdown.
2014-12-14WIP effort to update z80 core for code gen changesMichael Pavone
2014-12-03Temporarily comment out code to translate Z80 instructions in place as in ↵Michael Pavone
rare cases it can stomp the next instruction if a branch goes from a short from to a long one
