Snapshot is a savestate, i.e. the emulator records the exact state of the emulated console for future retrieval.
SRAM is emulation of on-cart saves (i.e battery backup for SNES and NES games).
If the game itself never had an in-game save function, then you'll have to use savestates. Otherwise, I think Tantric's emulators are set up intially to automatically save the SRAM when you save in game (I think, otherwise it just saves SRAM every 30 seconds or something).
If the game you are playing has no save function, then only use Save Snapshot and Load Snapshot with it. You might be able to set the option "Auto-load Snapshot" in the settings menu, which will boot up the most recent snapshot whenever you launch the game. Save SRAM will have no effect in such games.
Now, the emulators are admittedly not set up in favour of multiple savegame managing. Although it's no longer the case that each save overwrites the previous one, you don't have that much control. I think you can load older states, but I've deduced a more effective method:
What I recommend is copying the roms of whichever games you want to play (games with built-in multiple save files, like Zelda or FF don't matter), and renaming one of them, for example:
Harvest_Moon.smc
Harvest_Moon_(brother).smc
Then, whenever you want to play the game, you load the first rom, while your brother loads the second rom. This way, the emulator will create separate save files (Harvest_Moon.frz and Harvest_Moon_(brother).frz, I think) due to it treating the two roms as different games.
