age author description
Thu, 01 Jan 2015 20:07:47 -0800 Michael Pavone Use call_args and call_args_abi in Z80 core
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
Tue, 30 Dec 2014 19:11:34 -0800 Michael Pavone Merge
Tue, 16 Dec 2014 01:10:54 -0800 Michael Pavone Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc when using IX or IY. Fix access to I and R registers (R still needs to be made 7-bit though). Fix flags for ld a, i. The fix for access to I fixes PCM playback in Titan Overdrive and music playback in Crackdown.
Wed, 03 Dec 2014 09:30:01 -0800 Michael Pavone Temporarily comment out code to translate Z80 instructions in place as in rare cases it can stomp the next instruction if a branch goes from a short from to a long one

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.

Save the current value of the code_info struct for placing the final jmp instruction in the correct place

Mon, 06 Jan 2014 22:54:05 -0800 Michael Pavone The local clone on my laptop got messed up and some changes had not been 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.
