Mon, 23 Jun 2014 11:05:55 -0400 Mike Pavone Fix x86_rrindex_sizedir. Pass the correct scale to mov_rindexr in gen_mem_fun. BlastEm now sort of works on OS X. Runs reliably from lldb, but only intermittently from the shell

Fri, 14 Feb 2014 19:56:18 -0800 Michael Pavone Generate save_context and load_context functions at runtime

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
