Sitting on my todo-list for far too long
see pokefinder for similar implementation
PKHeX has a forward & reverse implementation available for 100% documentation purposes :)
The seed indicated in hover previews now matches that of the true Origin seed for the encounter (pre menu & accept dialog), similar to Method H/J/K encounters.

In addition to the Method 1 (and other sibling PIDIV types) correlation, an encounter can only be triggered if the calls prior land on the Method {1} seed. The RNG community has dubbed these patterns as "Method J" (D/P/Pt), "Method K" (HG/SS), and "Method H" (Gen3, coined by yours truly). The basic gist of these is that they are pre-requisites, like the Shadow locks of Colosseum/XD.
Rename/re-type a bunch of properties to get the codebase more in line with correct property names & more obvious underlying types.
Solution known for over a decade, finally reminded myself that it'd be nice to have this available. Probably will use this for displaying Method J/K/H frame info when that branch is more mature.
With the new version of Visual Studio bringing C# 12, we can revise our logic for better readability as well as use new methods/APIs introduced in the .NET 8.0 BCL.
Improve enc->ck3 creation, inline the shiny/gender reroll logic instead of trying again outside the loop.
Rewrite the pidiv logic to be more obvious
colo starters now show up in encdb list
Due to how the game generates the Pokémon data, the first two (or three) RNG calls are used to set the 32-bit `EncryptionConstant` and `PID`. With 2x 32-bit and 1x 64-bit values, we can algorithmically reverse the movement & manipulation of bits to recover the initial seed. Notably, certain bits of the initial state are not captured by our first two (or three) outputs, so we must brute-force guess at the initial state, and verify the RNG's output yields the expected values.
**With the ability for real-time Xoroshiro128+ seed reversal, we can now validate RNG correlations for SW/SH raid encounters natively within the program.** For now, the legality fail error message is extremely vague and any validated seed won't be "remembered" for the Legality Parse like other RNG methods. These seeds are 64bit, while every other "remembered" `PID/IV` seed-info is 32-bit.

Like move validation, evolutions are the earliest thing we wish to traverse when determining what encounters may have originated the current Pokémon. To determine the permitted species-form-levels a Pokémon could originate with, we must devolve a Pokémon by traveling down-generation to origin. Once we have an encounter, we can then evolve it to the current species, traversing upwards from origin to the current format.
Updates from net46->net7, dropping support for mono in favor of using the latest runtime (along with the performance/API improvements). Releases will be posted as 64bit only for now.
Refactors a good amount of internal API methods to be more performant and more customizable for future updates & fixes.
Adds functionality for Batch Editor commands to `>`, `<` and <=/>=
TID/SID properties renamed to TID16/SID16 for clarity; other properties exposed for Gen7 / display variants.
Main window has a new layout to account for DPI scaling (8 point grid)
Fixed: Tatsugiri and Paldean Tauros now output Showdown form names as Showdown expects
Changed: Gen9 species now interact based on the confirmed National Dex IDs (closes#3724)
Fixed: Pokedex set all no longer clears species with unavailable non-base forms (closes#3720)
Changed: Hyper Training suggestions now apply for level 50 in SV. (closes#3714)
Fixed: B2/W2 hatched egg met locations exclusive to specific versions are now explicitly checked (closes#3691)
Added: Properties for ribbon/mark count (closes#3659)
Fixed: Traded SV eggs are now checked correctly (closes#3692)
Can unroll the loop, but would look more ugly :)
JIT will probably do it for us.
Fix <= to < for IVs
Inline temp var (start is unused after assigning to low)
Big thanks to Parzival from the RNG discord community for chiseling the LCRNG search space down to the best performing implementation possible.
50x? Down from O(2^8) -> O(2^3) is 32x, but we no longer need to access two heap arrays (262KB no longer needed!). Everything can be calculated tightly with the stack.
f641f3eab2/RNG/LCG_Reversal.py (L31)
Rainbow tables is the only faster implementation. However, nobody is gonna hog many GB of RAM for O(1) reversals. This is ~O(2^3), down from O(2^8). Much better than the days of O(2^16)!
ShowdownSet: Lessen allocation
MoveTutor: Remove boxing by calling the generic method instead of object method
Xoro8b: Add more xmldoc, use positive constant instead of inverse negative for parity
StadiumUtil: Use built-in endianness reversal methods
Adds structures to read/write saved spawner data such as seeds, counts.
Adds generator and validator to emulate the FixInitSpec builder used by the game logic
Similar to SW/SH raids, validating these in-process is not feasible due to the number crunching required.
This does not handle the encounter slot call or the follow-up level range call. Just the inner FixInitSpec ctor & fill.
level is calc'd:
randFloat(sum) -> slot float
rand.Next() -> gen_seed (for all the details)
rand.NextInt(delta) +min -> level

Existing `get`/`set` logic is flawed in that it doesn't work on Big Endian operating systems, and it allocates heap objects when it doesn't need to.
`System.Buffers.Binary.BinaryPrimitives` in the `System.Memory` NuGet package provides both Little Endian and Big Endian methods to read and write data; all the `get`/`set` operations have been reworked to use this new API. This removes the need for PKHeX's manual `BigEndian` class, as all functions are already covered by the BinaryPrimitives API.
The `StringConverter` has now been rewritten to accept a Span to read from & write to, no longer requiring a temporary StringBuilder.
Other Fixes included:
- The Super Training UI for Gen6 has been reworked according to the latest block structure additions.
- Cloning a Stadium2 Save File now works correctly (opening from the Folder browser list).
- Checksum & Sanity properties removed from parent PKM class, and is now implemented via interface.
Big thanks to @SciresM @sora10pls @Lusamine @architdate @ReignOfComputer for testing and contributing code / test cases. Can't add co-authors from the PR menu :(
Builds will fail because azure pipelines not yet updated with net6.
