Don't lock up CPU if performing a read with writes configured when in PBC mode. Allow access to VDP debug commands from Z80 debugger in PBC mode. Handle Mode 4 in VDP debug print functions

Remove memory map assumptions from Z80 core and move a little bit of logic to the generic backend.c so it can be shared between CPU cores

Add a new memory map flag to support an auxilliary buffer for translating code from MMAP_PTR_IDX chunks for which the pointer is null

Change cycle tracking code for Z80 core to only use a single register. Store low 7 bits of R in a reg and increment it appropriately.

Initial stab at implementing address error exceptions. Need to fill in the value of IR, undefined bits of last stack frame word and properly deal with address errors that occur during exception processing.

Removed hardcoded assumptions in M68K core about which parts of the memory map are RAM

Made the Z80 core more contained by refactoring some code in blastem.c into z80_to_x86.c

All cycle counters are now based off the master clock. This seems to have messed up Z80 interrupt timing (music in Sonic 2 is too slow for instance), but things are generally working

Remove some of the hard coded assumptions about the memory map from the CPU cores

Fix handling of code writes for Z80 core. This seems to get things close to 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.

Split gen_mem_fun out of m68k_core_x86 and make it more generic so it can be used by the Z80 core
|

Refactored translate_m68k so that it contains no host-cpu specific code and moved it to m68k_core.c
|
| Sun, 02 Mar 2014 14:45:36 -0800 |

Refactor gen_x86 to use an interface more like gen_arm and to remove the need for the caller to decide whether an 8-bit or 32-bit displacement is needed in the rdisp functions. Update m68k_to_x86 to use the new version of the gen_x86 functions and do some minor refactoring there in the process

Moved some generic stuff from backend.h gen_arm.h and gen_arm.c into gen.h and gen.c. Added a couple fields to cpu_options so that gen_mem_fun can be made guest CPU generic
|
| Mon, 24 Feb 2014 01:30:16 -0800 |
Mike Pavone |
Use a typedef code_ptr in place of uint8_t * in 68K core to better support host instruction sets with different instruction word sizes. Make x86_68k_options contain a cpu_options so that gen_mem_fun can eventually be shared with the Z80 core.

Rename x86_backend.h and x86_backend.c to backend.h and backend.c respectively
