blastem.git - Oxore's fork of "blastem" emulator for ROM hacking (C)

Age	Commit message (Collapse)	Author
2014-03-02	Rename x86_68k_options and m68k_to_x86.h to m68k_options and m68k_core.h ↵	Michael Pavone
	respectively
2014-03-02	Refactor gen_x86 to use an interface more like gen_arm and to remove the ↵	Michael Pavone
	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
2014-03-02	Add backtrace (bt) command to 68K debugger	Michael Pavone

2014-02-24	Use 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.
2014-02-24	Rename x86_backend.h and x86_backend.c to backend.h and backend.c respectively	Mike Pavone

2014-02-18	Generate get_sr, set_sr and set_ccr at runtime so they can respect the ↵	Michael Pavone
	flag_regs setting
2014-02-16	Generate handle_cycle_limit at runtime so it can use the generated ↵	Michael Pavone
	save/load_context functions. Since the hand written versions of save/load are no longer used they have been removed.
2014-02-16	Generate native_addr and native_addr_and_sync at runtime so they can use the ↵	Michael Pavone
	generated save/load_context functions
2014-02-16	Generate retrans_stub at runtime so it can use the generated ↵	Michael Pavone
	save/load_context functions
2014-02-15	Get rid of the native stack option the 68K core. Trying to make it work with ↵	Michael Pavone
	code that messes with the stack is not worth the trouble.
2014-02-15	Generate m68k_start_context at runtime so it can use the generated ↵	Michael Pavone
	load_context and save_context
2014-02-14	Generate save_context and load_context functions at runtime	Michael Pavone

2013-09-10	Added copyright notice to source files and added GPL license text in COPYING	Mike Pavone

2013-05-21	m68k_trap is now replaced with a generated one so it can call the generated ↵	Mike Pavone
	memory acccess functions. The old static memory access functions have been removed from runtime.S
2013-05-21	Generate handle_cycle_limit_int at runtime so it can refer to the runtime ↵	Mike Pavone
	generated memory map functions
2013-05-18	Mostly working runtime generation of memory map read/write functions	Mike Pavone

2013-05-10	Initial stab at horizontal interrupts and improving accuracy of vertical ↵	Mike Pavone
	interrupts. Also added the VINT pending flag to status port.
2013-05-05	Add a YM2612 stub implementation with just timers and status registers so ↵	Mike Pavone
	that games that depend on it can run.
2013-04-30	Add a second context pointer to m68k_context so that try_fifo_write can ↵	Mike Pavone
	still have easy access to the VDP. Handle writes to Z80 code addresses from the 68K.
2013-04-29	Implement retranslating code when written to. Possibly broken, need to fix ↵	Mike Pavone
	some other bugs before a proper test.
2013-04-25	Get Z80 core working for simple programs	Mike Pavone

2013-04-16	Small bit of cleanup	Mike Pavone

2013-01-26	Tweaks to make blastem compatible with m68k-tester	Mike Pavone

2013-01-20	Add support for breaking into the debugger while game is running	Mike Pavone

2013-01-17	Add instruction address logging to translator and support for reading an ↵	Mike Pavone
	address log to the disassembler
2013-01-15	Implement support for self-modifying code	Mike Pavone

2013-01-14	Prep work for handling games that modify code in RAM	Mike Pavone

2013-01-13	Fix a bunch of bugs in the CPU core, add a 68K debugger	Mike Pavone

2013-01-04	Don't use the native call stack for M68K calls by default	Mike Pavone

2012-12-27	Initial work on allowing dynamic branches and code in RAM plus a small fix ↵	Mike Pavone
	to effective address decoding
2012-12-26	RTE doesn't crash the emulator anymore	Mike Pavone

2012-12-26	Initial stab at interrupt support. Make native code offsets bigger so I ↵	Mike Pavone
	don't have to worry about overflowing the offset. Implement neg and not (untested).
2012-12-21	Implement a couple of supervisor instructions	Mike Pavone

2012-12-18	Get Flavio's color bar demo kind of sort of working	Mike Pavone

2012-12-04	M68K to x86 translation works for a limited subset of instructions and ↵	Mike Pavone
	addressing modes
2012-11-27	x86 code gen, initial work on translator	Mike Pavone
