Update to v103 WIP release. 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.

Update to v102r10 release. byuu says: Changelog: - removed Emulator::Interface::Capabilities¹ - MS: improved the PSG emulation a bit - MS: added cheat code support - MS: added save state support² - MD: emulated the PSG³ ¹: there's really no point to it anymore. I intend to add cheat codes to the GBA core, as well as both cheat codes and save states to the Mega Drive core. I no longer intend to emulate any new systems, so these values will always be true. Further, the GUI doesn't respond to these values to disable those features anymore ever since the hiro rewrite, so they're double useless. ²: right now, the Z80 core is using a pointer for HL-\>(IX,IY) overrides. But I can't reliably serialize pointers, so I need to convert the Z80 core to use an integer here. The save states still appear to work fine, but there's the potential for an instruction to execute incorrectly if you're incredibly unlucky, so this needs to be fixed as soon as possible. Further, I still need a way to serialize array<T, Size> objects, and I should also add nall::Boolean serialization support. ³: I don't have a system in place to share identical sound chips. But this chip is so incredibly simple that it's not really much trouble to duplicate it. Further, I can strip out the stereo sound support code from the Game Gear portion, so it's even tinier. Note that the Mega Drive only just barely uses the PSG. Not at all in Altered Beast, and only for a tiny part of the BGM music on Sonic 1, plus his jump sound effect.
