crueter	08f3639c80	[desktop, fs] main_window separation; fix Ryujinx save data link issues (#2929 ) Some genius decided to put the entire MainWindow class into main.h and main.cpp, which is not only horrific practice but also completely destroys clangd beyond repair. Please, just don't do this. (this will probably merge conflict to hell and back) Also, fixes a bunch of issues with Ryujinx save data link: - Paths with spaces would cause mklink to fail - Add support for portable directories - Symlink detection was incorrect sometimes(????) - Some other stuff I'm forgetting Furthermore, when selecting "From Eden" and attempting to save in Ryujinx, Ryujinx would destroy the link for... some reason? So to get around this we just copy the Eden data to Ryujinx then treat it like a "From Ryujinx" op Signed-off-by: crueter <crueter@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/2929 Reviewed-by: Lizzie <lizzie@eden-emu.dev> Reviewed-by: CamilleLaVey <camillelavey99@gmail.com>	6 months ago
crueter	39f226a853	[qt] Ryujinx save data link (#2815 ) This adds an action to the Game List context menu that lets users link save data from Eden to Ryujinx, or vice versa. Unfortunately, this isn't so simple to deal with due to the way Ryujinx's saves work. Ryujinx stores its saves in the... config directory... in `bis/user/save`. Unlike Yuzu, however, it doesn't store things by TitleID, instead it's just a bunch of directories from 000...01 to 000...0f and so on. The way it maps TitleID to SaveID is via `imkvdb.arc` in `bis/system/save/8000000000000000/0/` and also an identical copy in the `1` directory for... some reason. `imkvdb.arc` is handled by `FlatMapKeyValueStore` in LibHac, which, as the name implies, is a key-value storage system that `imkvdb.arc`, and seemingly `imkvdb.arc` alone, uses. The way this class is written is really weird, almost as if it's designed to accommodate more types of kvdbs... but for now we can safely assume that there aren't gonna be any other `kvdb` implementations added to HorizonNX. Regardless, the file format is ridiculously simple so I didn't actually need to do a deep dive into C# code... of which I can basically only read Avalonia. A simple `xxd` on the `imkvdb.arc` is all that's needed, and here's everything that matters: - The `IMKV` magic header (4 bytes) - 8 bytes that don't really have anything useful to us, except for a size byte (presumably a `u32`) strewn at offset `0x08` from the start of the file, which is useless to us - Then we start the `IMEN` list. I don't know what the `IM` stands for, but `IMEN` is just, well, an ENtry. Offsets shown are relative to the start of the `IMEN` header. * 4-byte `IMEN` magic header at 0x0 * 8 bytes of filler data. It contains two `0x40` bytes, but I'm not really sure what they do * TitleID (u64) at `0xC`, for example `00a0 df10 501f 0001` for Legends: Arceus (the byte order is swapped) * 0x38 bytes of filler starting at offset 0x14 * SaveID (u64) at `0x4C`, for example `0a00 0000 0000 0000` for my Legends: Arceus save * 0x38 bytes of filler starting at offset 0x54 Full example for Legends: Arceus: ``` 000001b0: 494d 454e 4000 0000 4000 0000 00a0 df10 IMEN@...@....... 000001c0: 501f 0001 0100 0000 0000 0000 0000 0000 P............... 000001d0: 0000 0000 0000 0000 0000 0000 0100 0000 ................ 000001e0: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 000001f0: 0000 0000 0000 0000 0000 0000 0a00 0000 ................ 00000200: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000210: 0000 0000 0100 0000 0000 0000 0000 0000 ................ 00000220: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000230: 0000 0000 0000 0000 0000 0000 494d 454e ............IMEN ``` Ultimately, the size of the `IMEN` sits at 0x8C or 140 bytes. With this knowledge reading all the TitleID -> SaveID pairs is basically free, and outside of validation and stuff is like 15 lines of relevant code. Some interesting caveats, though: - There are two entries for some TitleIDs for... some reason? Ignoring the second one seems to work though. - Within each save directory, there are directories `0` and `1`... and only `0` ever seems used??? It's where Ryujinx points you to for save, so I just chose to use that. Once everything is parsed, the rest of the implementation is extremely trivial: - When the user requests a Ryujinx link, match the current program_id to the corresponding SaveID in `imkvdb` - If it doesn't exist, just error out (save data is probably nonexistent) - If it does though, give the user the option to use Eden's current save data OR Ryujinx's current save data. Old save data is deleted depending on which one you chose.

crueter	a53823646c	[qt] fix translations (#2773 ) Linguist strongly dislikes lookup tables of this sort due to the fact that it looks for tr(), qsTr(), etc. when determining what strings need translations. However, it does provide QT_TR_NOOP which marks the string for translation without running the translation, which is designed to allow for static or constexpr lookup tables. So let's use that.

crueter	badd913bee	[desktop] fix save data location, orphaned profiles finder (#2678 ) Previously, if the user had their NAND in a nonstandard location, profiles.dat would be read from the standard Eden path and thus return effectively garbage data. What this would result in is: - The Qt profile manager would be completely nonfunctional - "Open Save Data Location" would put you into the completely wrong place - Games would read from incorrect locations for their saves To solve this, I made it so that profiles.dat is re-read after QtConfig initializes. It's not the perfect solution, but it works. Additionally, this adds an orphaned profiles finder: - walks through the save folders in nand/user/save/000.../ - for each subdirectory, checks to see if profiles.dat contains a corresponding UUID - If not, the profile is "orphaned". It may contain legit save data, so let the user decide how to handle it (famous last words) - Empty profiles are just removed. If they really matter, they're instantly recreated anyways. The orphaned profiles check runs right after the decryption keys check, but before the game list ever gets populated Signed-off-by: crueter <crueter@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/2678 Reviewed-by: CamilleLaVey <camillelavey99@gmail.com> Reviewed-by: MaranBr <maranbr@eden-emu.dev>	7 months ago
