ESLs were not supported in VR. This was a page to aggregate data for VR for any attempts to add it. This is left for reference.

AFKMods discussion on ESL/ESP difference Save game format 1.5.97 address for .esl: 141632ac8

TESFile->smallFileCompileIndex looks to be just padding in VR. We can treat TESFile as the SE version and we likely won't overwrite any actual data

TESFile->currentform.formid in (TESFile__ReadFormHeader_14018EAD0) has plugin index equal to master index in master list (ex: "AAA.esp" has Skyrim, Dragonborn as masters. 0 = Skyrim.esm, 1 = Dragonborn.esm, 2 = AAA.esp).

Potentially relevant functions:

Name	SSE	VR	Notes
bool TESFile::IsESL_14017E160 (TESFile * param_1)	14017E160
void TESFile::AdjustFormIDFileIndex(TESFile *a_this,uint *a_formid)	14017e180		Used to set formids for ESL files; need in VR
bool TESFile::SetCompileIndex_14017C63 (TESFile * a_file, int a_index)	14017C63	14018C480
PluginLoader?	14050eea0	14051dc00
LoadPluginBSA	140173BD0	140184360
TESDataHandler::ctor	140166D80	1401774C0	functions relevant for forms/formIDs/etc.
TESDataHandler::CompileFiles_14017EFF0	14016E660	14017EFF0	DataHandler->LoadingFiles set to true AND false here. offset 0x14A seems to be where masters are set above regular files. loadedModCount reset if a_unk is true, maybe this is where the plugins are parsed/loaded?
iFormsLoaded	141EC3B60	141F889C0	Named from FO4
TESDataHandler::ConstructObjectList_140180870	1401700E0	140180870	Named from FO4

Functions we should modify:

Name	SSE	VR	Modification treatment	isCompleted
TESDataHandler::sub_14017EFF0	14016E660	14017EFF0	ASM hook 5 spots where loadedmods is used, replace with TESFileCollection
TESDataHandler::AddFile		14017EFF0	Replace entire function with SSE or near SSE equivalent; uses TESFile::IsESL
sub_1401831F0		1401831F0	ASM replace 0x807-852. Jmp to function to add TESFile the way SSE does (ESP/ESL split)
TESFile::GetCompileIndex_14018C470		14018C470	Seems used for File checking/form ID setting. Fixes uses of this!
TESFile * TESNPC::GetFaceTint (TESNPC * a_this, undefined8 param_2, undefined8 param_3)	1403602b0	14036fb70	Uses TESFile::IsESL, sets bitmask to 0xFFF if ESL, 0xFFFFFF if not ESL
bool TESNPC::GenerateFaceGenData (TESNPC * a_this, undefined8 param_2)	140363210	140372b30	Uses TESFile::IsESL, but similar to GetFaceTint test appears unused?
void FUN_14038dcb0 (longlong param_1, char * param_2, TESForm__VFTable * param_3, TESForm * param_4)	14038dcb0	14039d660	Uses TESFile::IsESL, but SSE test looks unused?
bool TESDataHandler::FUN_1401703f0 (TESDataHandler * a_this, TESFile * a_file, bool a_isFirstPlugin, TESWorldSpace * a_worldspace)	14038dcb0	140180b80	Uses TESFile::AdjustFormIDFileIndex
bool TESFile::ReadFormHeader_14017ed70 (TESFile * param_1)	14017ed70	14018ead0	Uses TESFile::AdjustFormIDFileIndex
void FUN_1401957e0(uint *form_id,TESFile *param_2)	1401957e0	1401a5510	Uses TESFile::AdjustFormIDFileIndex
uint TESFile::FUN_14057cc20 (TESFile * param_1, uint param_2)	14057cc20		Uses TESFile::AdjustFormIDFileIndex
TESForm * papyrus__Game::GetFormFromFile_140972E10 (undefined8 a_vm, undefined4 a_stackID, undefined8 param_3, uint a_formid, char * a_modname)	140972e10	1409acca0	Uses TESFile::AdjustFormIDFileIndex
BGSSaveGameBuffer::sub_140585580	14057DDE0	140585580	Treat as SE, loop through regular files first, then small files afterwards and save their count/names
sub_1404B80A0	1404A8090	1404B80A0	Use only regular files in loop, ESLs ignored here in SE for some reason
sub_140585640	14057DF20	140585640	Loads and checks file names. Use handler->files instead of handler->loadedMods
TESFile * TESFile::FUN_14017f2d0 (TESFile * param_1, undefined4 param_2)	14017f2d0	14018f060	Copies a_this_00->SmallFileCompileIndex_47A = param_1->SmallFileCompileIndex_47A in SSE
BSTArrayHeapAllocator * TESFile::FUN_14017b000 (TESFile * param_1, longlong param_2)	14017b000	14018aeb0	Sets ESL record flag
undefined8 FUN_140c2c0c0 (void)	140c2c2bf	140c71186	Loads Plugins from plugins.txt. Needs to also add .esl
sub_14052D230	140536330	14052D230	Add ".ESL" check in addition to ESP/ESM
TESDataHandler__sub_14017E540	14016DBB0	14017E540	Add ".ESL" check in addition to ESP/ESM

Compare SSE vs VR

Assembly does a test but doesn't branch based on it?
