Mesen: Open the Debugger window and select Import/Export > Import Labels. Select the .msl or '.mlb' file to add labels to the debugger view and trace logs.
bsnes-plus: Rename the .sym file to match your ROM and place it in the same directory. Load the ROM to load the symbols, which will take longer with the _wram version.
asar: You can incsrc wram_symbols.asm in your ASM files to add labels for WRAM addresses to your assembly projects. Add --symbols=wla --symbols-path=Debug_Symbols.sym as a command line option to generate WLA symbols when assembling. These symbols can also be imported into Mesen-S/Mesen2/bsnes-plus.

A copy of the RAM map is included in the repo for the purpose of tracking changes and making updates easier. Original source for this file is linked below
Thanks to P.JBoy for the RAM map, bank logs, and generated labels we started with. Also Metroid Construction :)
