age author description
Wed, 25 Nov 2015 08:40:45 -0800 Michael Pavone Partially working change to do proper stack alignment rather than doing a lame alignment check when calling a C compile dfunction. 68K core seems okay, but Z80 is busted.
Sat, 14 Nov 2015 13:56:41 -0800 Michael Pavone Prevent the current interrupt number from being changed while interrupt is being processed. This fixes a bug in Sonic 2 split screen that showed up when interrupt timing was adjusted

Sat, 25 Jul 2015 18:22:07 -0700 Michael Pavone Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).

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 13:14:09 -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

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 17:31:59 -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
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.
Sun, 28 Dec 2014 17:25:36 -0800 Michael Pavone Removed bcd_add and bcd_sub from runtime.S and generated the logic inline with the rest of abcd and sbcd translation. Fixed some edge cases and undefined flag behavior in the process
