2014-12-26Get Z80 banked access sort of working againMichael Pavone
2014-12-26Set int_cycle to CYCLE_NEVER in sync_z80 so that the interrupt routine isn't ↵Michael Pavone
taken inappropriately now that the kludge in handle_cycle_limit_int has been removed
2014-12-22Z80 core is sort of working againMichael Pavone
2014-12-17Get rest of emulator compiling again with Z80 core enabledMichael Pavone
2014-12-14WIP effort to update z80 core for code gen changesMichael Pavone
2014-12-03Initial support for configurable IO, custom IO and sega transfer board emulationMichael Pavone
2014-06-21Fix Z80 interruptsMichael Pavone
2014-06-19Slight cleanup of vint handling on the Z80Michael Pavone
2014-06-18Fix most of the breakage caused by the vcounter/hcounter changesMichael Pavone
2014-06-17blastem builds and almost works on OS X nowMike Pavone
2014-03-02Initial stab at separating the generic parts of the 68K core from the ↵Michael Pavone
host-cpu specific parts.
2014-03-02Rename x86_68k_options and m68k_to_x86.h to m68k_options and m68k_core.h ↵Michael Pavone
respectively
2014-03-01Add a separate flag/define for disabling the Z80 at compile time to ease ↵Michael Pavone
refactoring
2014-02-24Use a typedef code_ptr in place of uint8_t * in 68K core to better support ↵Mike Pavone
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.
2014-02-18Initial work on the x86-32 targetMichael Pavone
2014-02-13Properly sync hardware when frame end is reached during DMAMike Pavone
2014-02-12Update version numberMike Pavone
2014-02-12Remove defines from blastem.c that had been moved to blastem.hMike Pavone
2014-02-11Move debugging code outside of main source fileMike Pavone
2014-02-09Added step and step-over debugger commands. step-over is like next except it ↵Mike Pavone
doesn't follow conditional branches to lower addresses. This makes it useful for advancing to the end of a loop. Also fixed a bug in next introduced by the refactor.
2014-02-09Refactor debugger next commandMike Pavone
2014-02-09Properly handle dbcc, rtr and rte in the debugger next commandMike Pavone
2014-02-09Properly handle jmp instructions in the debugger next commandMike Pavone
2014-02-08Initial GDB remote debugging support. Lacks some features, but breakpoints ↵Mike Pavone
and basic inspection of registers and memory work.
2014-02-06Add a zp command to the 68K debugger to allow printing Z80 registers while ↵Michael Pavone
in the 68K debugger
2014-02-03Initial attempt at emulating extended bank area access delays when 68K bus ↵Michael Pavone
is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.
2014-01-06The local clone on my laptop got messed up and some changes had not been ↵Michael Pavone
pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.

2013-10-28Extract function to determine executable directory from load_config so it ↵Mike Pavone
can be used elsewhere

2013-10-01Implement turbo/slow motion feature that overclocks or underclocks the ↵Mike Pavone
entire system at the push of a button
2013-09-18Theoretically more correct timing of Z80 bus requestMike Pavone
2013-09-15Implement FIFO as a ring buffer so the behavior of reads from invalid CRAM ↵Mike Pavone
and VSRAM bits can be implemented properly
2013-09-13Properly delay 68K on VDP reads. Dummy VDP test port implementation. Initial ↵Mike Pavone
stab at handling undefined bits of VSRAM and CRAM.
2013-09-11Fix argument handling so that the rom filename does not need to be specified ↵Mike Pavone
first
2013-09-10Added copyright notice to source files and added GPL license text in COPYINGMike Pavone
2013-09-10Added version flagMike Pavone

2013-09-02Adjust VBLANK flag and refresh timing to be in line with logic analyzer and ↵Mike Pavone
visual observations of direct color DMA demos. Remove debug print statements.
2013-09-01MergeMike Pavone
2013-09-01Fix bug that caused a DMA fill to start after another DMA operation ↵Mike Pavone
completed if the FIFO is not empty
