Wed, 19 Feb 2014 00:44:19 -0800 Michael Pavone Fix type mismatch on headless global that was causing a crash in the vgm player on ARM
Wed, 19 Feb 2014 00:22:27 -0800 Michael Pavone Apart from the Z80 core, BlastEm now supports 32-bit x86
Tue, 18 Feb 2014 23:19:07 -0800 Michael Pavone Properly null terminate string returned by readlink in util.c
Tue, 18 Feb 2014 21:37:31 -0800 Michael Pavone Initial work on the x86-32 target
Tue, 18 Feb 2014 20:32:10 -0800 Michael Pavone Generate get_sr, set_sr and set_ccr at runtime so they can respect the flag_regs setting
Mon, 17 Feb 2014 19:58:37 -0800 Michael Pavone Make references to flags in the M68K core respect the flag_regs options array so that flags can be moved out of registers for the 32-bit port. set/get ccr/sr still need to be updated to support this, but everything else should be done.
Sun, 16 Feb 2014 19:54:27 -0800 Michael Pavone Generate handle_cycle_limit at runtime so it can use the generated save/load_context functions. Since the hand written versions of save/load are no longer used they have been removed.

Sat, 15 Feb 2014 22:35:18 -0800 Michael Pavone Get rid of the native stack option the 68K core. Trying to make it work with code that messes with the stack is not worth the trouble.
Sat, 15 Feb 2014 21:25:36 -0800 Michael Pavone Generate m68k_start_context at runtime so it can use the generated load_context and save_context
Fri, 14 Feb 2014 19:56:18 -0800 Michael Pavone Generate save_context and load_context functions at runtime

Sun, 09 Feb 2014 17:16:55 -0800 Mike Pavone Added step and step-over debugger commands. step-over is like next except it 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.

Mon, 03 Feb 2014 09:18:10 -0800 Michael Pavone Initial attempt at emulating extended bank area access delays when 68K bus 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.
Tue, 28 Jan 2014 08:36:06 -0800 Michael Pavone Add 3 wait states to Z80 access to bank area since that seems to be roughly the average in normal usage
