age author description
Sat, 03 Jan 2015 18:27:29 -0800 Michael Pavone Removed some obsolete defines
Sat, 03 Jan 2015 18:23:04 -0800 Michael Pavone Made the Z80 core more contained by refactoring some code in blastem.c into z80_to_x86.c
Sat, 03 Jan 2015 16:08:23 -0800 Michael Pavone 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
Fri, 02 Jan 2015 13:47:34 -0800 Michael Pavone In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed
Fri, 02 Jan 2015 13:14:09 -0800 Michael Pavone Added functions to gen_x86 for saving and restoring callee save registers to better abstract over ABI differences between x86 and x86-64
Fri, 02 Jan 2015 12:04:58 -0800 Michael Pavone Use SZ_PTR instead of SZ_Q in Z80 core for 32-bit compat

Thu, 01 Jan 2015 23:37:24 -0800 Michael Pavone Remove dedicated registers for Z80 bank reg and Z80 bank pointer as they are no longer used
Thu, 01 Jan 2015 22:52:18 -0800 Michael Pavone Adjust 68K sync cycle when mclk_target gets adjusted
Thu, 01 Jan 2015 22:18:32 -0800 Michael Pavone Add the 3 cycle delay back in to Z80 bank area access
Thu, 01 Jan 2015 20:26:22 -0800 Michael Pavone Minor Z80 core cleanup
Thu, 01 Jan 2015 20:21:20 -0800 Michael Pavone Use call_args and call_args_abi inside gen_mem_fun
Thu, 01 Jan 2015 20:07:47 -0800 Michael Pavone Use call_args and call_args_abi in Z80 core
Thu, 01 Jan 2015 19:15:05 -0800 Michael Pavone Added 2 new functions to gen_x86.c for handling passing args according to the C abi of the host system and adapted the code in m68k_core_x86.c to use that instead of doing everything by hand
Thu, 01 Jan 2015 17:36:23 -0800 Michael Pavone Avoid calling atexit(SDL_Quit) until after OpenGL initialization to avoid a segfault on exit when using fglrx
Thu, 01 Jan 2015 17:31:59 -0800 Michael Pavone Fix some issues with 68K instruction retranslation
Thu, 01 Jan 2015 14:36:55 -0800 Michael Pavone Remove some of the hard coded assumptions about the memory map from the CPU cores
Tue, 30 Dec 2014 19:11:34 -0800 Michael Pavone Merge
Tue, 16 Dec 2014 01:10:54 -0800 Michael Pavone Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc 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.

Wed, 03 Dec 2014 09:30:01 -0800 Michael Pavone Temporarily comment out code to translate Z80 instructions in place as in rare cases it can stomp the next instruction if a branch goes from a short from to a long one

Tue, 17 Jun 2014 19:01:01 -0700 Michael Pavone 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
Mon, 16 Jun 2014 19:13:28 -0700 Michael Pavone Fix a few values reported by the vr debugger command. Add DMA registers to vr debugger command. Fix horizontal interrupt bug. Slightly more accurate (but still broken) handling of switches between H32 and H40 modes.
Mon, 29 Dec 2014 23:08:39 -0800 Michael Pavone 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.
