Rewrites a good amount of legality APIs pertaining to:
* Legal moves that can be learned
* Evolution chains & cross-generation paths
* Memory validation with forgotten moves
In generation 8, there are 3 separate contexts an entity can exist in: SW/SH, BD/SP, and LA. Not every entity can cross between them, and not every entity from generation 7 can exist in generation 8 (Gogoat, etc). By creating class models representing the restrictions to cross each boundary, we are able to better track and validate data.
The old implementation of validating moves was greedy: it would iterate for all generations and evolutions, and build a full list of every move that can be learned, storing it on the heap. Now, we check one game group at a time to see if the entity can learn a move that hasn't yet been validated. End result is an algorithm that requires 0 allocation, and a smaller/quicker search space.
The old implementation of storing move parses was inefficient; for each move that was parsed, a new object is created and adjusted depending on the parse. Now, move parse results are `struct` and store the move parse contiguously in memory. End result is faster parsing and 0 memory allocation.
* `PersonalTable` objects have been improved with new API methods to check if a species+form can exist in the game.
* `IEncounterTemplate` objects have been improved to indicate the `EntityContext` they originate in (similar to `Generation`).
* Some APIs have been extended to accept `Span<T>` instead of Array/IEnumerable
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.
Closes#3318
Gen8: if held item, only give if can be legally held; if dmax crystal, only give if available.
Gen8b: if held item, only give if can be legally held
Others: unimplemented; pull requests accepted.
Still does the same silly ARNG as gen4:
seed = 0x6C078965 * seed + 1;
to advance on each day
Do note that it sets event flag 1711 to true, and sets the absolute value of the "Random" to Work[436]. FLAG_DAILY_RANDOM, WK_DAILY_RANDOM, assumedly for easy use with scripts.
The RAM is pretty dirty for unallocated poffins; slots that have never been filled will have junk with whatever the unallocated pointer was looking at.
An empty poffin slot is just marked as FF, ignores the stats for that slot. Not sure on the naming, but Matt had a single Level 60 poffin -> must be Mild? Thus, all the names are -1 from the textfile array...
Closes#3305
I think it was actually crashing due to the bad GameClear date record, not this extra record data, but we'll still update the head record
Fix note of ENC_SV_DATA start offset now that we know the real size of Record8b
Add actual maximums for all record entries
