Some pieces of code are calling IsRunning because there's some
particular action that only makes sense when emulation is running, for
instance showing the state of the emulated CPU. IsRunning is appropriate
to use for this. Then there are pieces of code that are calling
IsRunning because there's some particular thing they must avoid doing
e.g. when the CPU thread is running or IOS is running. IsRunning isn't
quite appropriate for this. Such code should also be checking for the
states Starting and Stopping. Keep in mind that:
* When the state is Starting, the state can asynchronously change to
Running at any time.
* When we try to stop the core, the state gets set to Stopping before we
take any action to actually stop things.
This commit adds a new method Core::IsUninitialized, and changes all
callers of IsRunning and GetState that look to me like they should be
changed.
This lets us reduce the number of USE_RETRO_ACHIEVEMENTS ifdefs in the
code base, reducing visual clutter. In particular, needing an ifdef for
each call to IsHardcodeModeActive was annoying to me. This also reduces
the risk that someone writes code that accidentally fails to compile
with USE_RETRO_ACHIEVEMENTS disabled.
We could cut down on ifdefs even further by making HardcodeWarningWidget
always exist, but that would result in non-trivial code ending up in the
binary even with USE_RETRO_ACHIEVEMENTS disabled, so I'm leaving it out
of this PR. It's not a lot of code though, so I might end up revisiting
it at some point.
There were three distinct mechanisms for signaling symbol changes in DolphinQt: `Host::NotifyMapLoaded`, `MenuBar::NotifySymbolsUpdated`, and `CodeViewWidget::SymbolsChanged`. The behavior of these signals has been consolidated into the new `Host::PPCSymbolsUpdated` signal, which can be emitted from anywhere in DolphinQt to properly update symbols everywhere in DolphinQt.
Play Input Recording would potentially unlock achievements without any player input and needs to be disabled. If a recording is already playing, hardcore mode cannot be enabled.
Frame advancing is easily exploitable for slowing down a game and artificially improving reaction times and is not allowed in RetroAchievements hardcore mode.
While saving states is allowed (especially for the purpose of debugging), RetroAchievements does not allow loading saved states when hardcore mode is on.
There's no reason not to allow this now that these settings are
cleanly integrated into the new config system. (Actually, maybe
we could even have done this before the previous commit...)
This fixes a problem where changing the JIT debug settings on
Android while a game was running wouldn't cause the changed settings
to apply to code blocks that already had been compiled.
AchievementsWindow is the dialog box that will eventually contain the settings and progress data for RetroAchievements on Dolphin. This adds the barebones dialog, and connects it to MainWindow's MenuBar.
ESCore implements the core functionality that can also be used outside of emulation. ESDevice implements the IOS device and is only available during emulation.
This fixes a problem I was having where using frame advance with the
debugger open would frequently cause panic alerts about invalid addresses
due to the CPU thread changing MSR.DR while the host thread was trying
to access memory.
To aid in tracking down all the places where we weren't properly locking
the CPU, I've created a new type (in Core.h) that you have to pass as a
reference or pointer to functions that require running as the CPU thread.

This should be a fairly easy merge, assuming I didn’t mess anything up. TL:DR no one uses it and it’s not great.
Boot from DVD Backup is an ancient feature with origins in the Megacommit. Back then, GameCube and Wii games were quite large relative to drives of the time. For example, in 2008, the most common hard drive sizes were 320GB and 512GB. On the 320GB drive I personally had at the time, as little as 42 Wii ISOs could have filled it entirely! And that’s ignoring any other files one might want to put onto a drive. Backup DVDs allowed users to burn relatively cheap DVD media and store their GameCube and Wii dumps in a Dolphin accessible way that didn’t eat into their precious HDD space. It had compromises, even then, but in 2008… I mean honestly users probably wouldn’t even notice those compromises with how Dolphin barely even worked at all back then.
Obviously, today the storage space concerns are not as big of an issue. According to seagate the average hard drive it sells today is 8TB. For typical laptops purchased now, the -minimum- selection for storage is usually 1TB. You can even buy a name brand 4TB external hard drive for $100. GC and Wii ISOs are not as big as they once were, relatively anyway. Plus flash drives and SD cards are super cheap and way faster than disc drives ever were. For anyone that has limited drive space, removable flash media can fulfill this offloading role far better than backup DVD media ever could.
Also no one has DVD drives anymore. That’s kind of an important detail.
But to see if Booting from DVD Backup even still worked, I decided to give it a try. I have an ASUS BW-16D1HT, a badass Bluray XL reading and burning drive, connected to my Windows 11 Threadripper 5975WX machine. A super fast drive on a super fast machine is as good as it possibly can get for this feature. So I bought a spindle of DVD-Rs, burned a couple of discs and gave it a try. Surprisingly, it does still work. However, as expected, it introduces a lot of stuttering. Testing Prime 1 and Prime 3, in both games stuttering was introduced whenever the DVD Drive had to suddenly seek. Spikes of 50ms occurred constantly, but I observed 150ms and even over 1000ms stutters! The worst was a three second stutter, when loading Elysia in Prime 3. I could even hear the stutters - any time the drive suddenly made a harsh seeking noise, the game would have a hard stutter. It worked but, it has some serious compromises.
Boot from DVD Backup isn’t great, using removable flash media or external hard drives is a FAR better option for anyone with limited storage space today, and no one can even use this feature anymore because their computers don’t even have disc drives. It’s time for Boot from DVD Backup to go!
So I did my best on the cleanup but I’m bound to have left some bits. Especially in translation - I didn’t get any warnings or anything there that could help point me to where to clean that up. Please review!
