byuu says (in the WIP forum):
Changelog:
- higan: cheat codes accept = and ? separators now
- the new preferred code format is: address=value or
address=if-match?value
- the old code format of address/value and address/if-match/value
will continue to work
- higan: cheats.bml is no longer included with the base distribution
- mightymo stopped updating it in 2015, and it's not source code;
it can still be pulled in from older releases
- fc: improved PAL mode timing; use PAL APU timing tables; fix PAL
noise period table [hex\_usr]
- md: support aborting a Z80 bus wait in order to capture save states
without freezing
- note that this will violate accuracy; but in practice a slight
desync is better than an emulator deadlock
- sfc: revert DSP ENDX randomization for now (want to research it more
before deploying in an official release)
- sfc: fix Super Famicom.sys/manifest.bml APU RAM size [hex\_usr]
- tomoko: cleaned up make install rules
- hiro/cocoa: use ABGR for pixel data [Sintendo]
Note: I forgot to change the command-line and drag-and-drop separator
from : to | in this WIP. However, it is corrected in the v103 official
binary and source published on download.byuu.org. Sorry about that, I
know it makes the Git repository history more difficult. I'm not
concerned whether the : → | change is part of v103 or v103r01 in the
repository, and will leave this to your discretion, Screwtape.
I also still need to set the VDP bit to indicate PAL mode in the Mega
Drive core. This is what happens when I have 47 things I have to do,
given how lousy my memory is. I miss things.
