Since ccf92a3e56, recording fifologs multiple times after launching dolphin caused all initial state to not be saved (the initial contents of bpmem, cpmem, etc were all zeroed out). For some games, this was not noticeable, as most registers were set each frame, but for others, this resulted in completely broken fifologs. (Note that recording fifologs also required 05181f6b88 and 9e0755a598 to be cherry-picked due to other, since fixed, regressions.)
This was because previously, `Renderer::CheckFifoRecording` was called every frame, but ccf92a3e56 changed it into a callback (`m_end_of_frame_event`) that was removed when recording ended. Thus, before, `OpcodeDecoder::g_record_fifo_data = IsRecording()` was called when `IsRecording()` returned false, but after that commit `g_record_fifo_data` never got changed back to false, so the check for `was_recording` only ever passed on the first fifolog recorded (even after stopping and starting a game).
There may still be another issue lurking, as I'm not sure if all broken fifologs were caused by recording multiple fifologs (for instance, on https://bugs.dolphin-emu.org/issues/13377, only one fifolog was initially uploaded, but it was affected by an issue with the same symptoms as this).
Instructions referencing registers r8-r15 take an additional byte to
encode. `reg_downcount` may be assigned to one of these registers, so it
is a small size win to store the downcount value in `RSCRATCH` first.
Before:
33 D2 xor edx,edx
44 8B 6D 64 mov r13d,dword ptr [rbp+64h]
45 85 ED test r13d,r13d
7E 30 jle 0000023546B43F6D
44 8B B5 D4 02 00 00 mov r14d,dword ptr [rbp+2D4h]
41 8B C5 mov eax,r13d
BF 07 00 00 00 mov edi,7
F7 F7 div eax,edi
After:
33 D2 xor edx,edx
8B 45 64 mov eax,dword ptr [rbp+64h]
85 C0 test eax,eax
7E 30 jle 000001AFBBAE359D
44 8B B5 D4 02 00 00 mov r14d,dword ptr [rbp+2D4h]
44 8B E8 mov r13d,eax
BF 07 00 00 00 mov edi,7
F7 F7 div eax,edi
This value is used in a multiplication. The result of this
multiplication is then subtracted from m_base. By negating m_dec, we are
free to use an addition instead.
On x64, this saves an instruction.
Split the "welcome" messages letting players know achievements are active into a separate method that gets called (currently) after a number of frames to ensure that the emulator has started properly and has somewhere to display the messages.
A new tab is added to the Achievements dialog to chart out the leaderboards in a table. Each row of the table contains the leaderboard information and up to four relevant entries, varying based on how many entries are in the leaderboard, whether or not the player has a submitted score, and where in the leaderboard the player's score is.
FetchBoardInfo is called (via the work queue asynchronously) on a leaderboard every time it is activated or submitted to. It makes two calls to the RetroAchievements API for fetching leaderboard info, one that requests the top four entries in the leaderboard and another that requests the player's entry, the two entries above the player and the two entries below. All of these are inserted into a single map (resolving any overlaps) so the result can be exposed to the UI.
The leaderboard map created here contains information useful to displaying leaderboard stats in the Achievement dialog, including each leaderboard's name and description and a partial list of entries for display. The entire map is exposed to the UI in a single call for simplicity.
Both of these functions access `m_game_data` and don't lock themselves, so they must be called in a way that guarantees that `m_game_data` is not modified during the call.
Scope issue in the event callback from `rc_runtime_do_frame()`. The pointer points to a variable on the stack from inside `rc_runtime_do_frame()`, so that's a race condition between the thread calling `rc_runtime_do_frame()` and the event queue thread.
Added handling to Achievement Progress Events, which are generated when an achievement with a Measured field updates in value. For example, an achievement for collecting 120 stars will throw this event when the player collects each star, and with this handling, the player will get a message on screen informing them of this progress. This message will only appear if the newly added RA_PROGRESS_ENABLED setting is true.
A deep-copy method CopyReader has been added to BlobReader (virtual) and all of its subclasses (override). This should create a second BlobReader to open the same set of data but with an independent read pointer so that it doesn't interfere with any reads done on the original Reader.
As part of this, IOFile has added code to create a deep copy IOFile pointer onto the same file, with code based on the platform in question to find the file ID from the file pointer and open a new one. There has also been a small piece added to FileInfo to enable a deep copy, but its only subclass at this time already had a copy constructor so this was relatively minor.
The achievement badges will now have a blue or gold border to identify whether they have been unlocked in softcore or hardcore mode. Similarly, the game badge will have a blue border if all achievements have been unlocked in either mode or a gold border if all achievements have been unlocked in hardcore mode.
Provided the badges are turned on in the settings, each achievement will have a badge next to it on the progress tab. There are different badges for locked and unlocked (usually locked is grayscale while unlocked is in color but not necessarily) and the badge chosen depends on the player's current unlock and hardcore status.
Provided badges are turned on, if there's a player logged in their RetroAchievements icon will appear next to their player info in the header of the Achievements dialog. If they're playing a game, so will the icon for the game. Also performed some refactoring and reorganizing to the header as a whole so that it looks consistent whether a game is running or not.
FetchBadges fetches all available badges (player, game, achievements) and stores them in AchievementManager's memory. New fields and accessors have been added as necessary. Badges for individual achievements are stored in the UnlockStatus map. The method is public so that the settings dialog can call it if badges are turned on after a game is started. Badges are deleted at game close and logout.
When evaluating whether jo.fastmem should be set to true, we check the
value of jo.fastmem_arena. However, due to a change made in 28e8117b90,
jo.fastmem_arena wasn't set until after the first time we set
jo.fastmem, so jo.fastmem would end up always being false until the next
time RefreshConfig was called.
Fixes https://bugs.dolphin-emu.org/issues/13364.
Image requests from RetroAchievements have a slightly different format from other requests, on account of being GET calls that return strings of image data, so this is a separate function that makes such calls. To handle this, I create a BadgeStatus object that ties each badge to a boolean flag for whether it is loaded and thus usable.
