|
Tue, 17 Jun 2014 19:01:01 -0700 |

Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though

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.

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

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.

|
Mon, 17 Feb 2014 19:58:37 -0800 |
Michael Pavone |
