Well, emulators like Genecyst or MEKA let you view the hardware at work, for example the color palette or the video RAM. ZSNES lacks such features, but the savestates contain all the info. A savestate is like a SNES frozen in time.

vSNES comes with several tools:

1. The Preview Window shows you the picture that is included in the ZSNES or Super Sleuth savestate file.
2. The MemViewer allows you to view the content of VRAM, WRAM and the cartridge using the colors selected in the PalViewer.
3. The SceneViewer shows you the current screen of the SNES and the parts it consists of (i.e. regular backgrounds, sprites, Mode7 backgrounds, HDMA and offset-per-tile info).
4. The HexEditor shows the content of the larger RAM or ROM arrays as bytes and as text, and allows you to edit them.
5. The List Editor allows you to edit the values in the main list.
6. The SPCViewer shows the header, the ID666 tag and the extended ID666 tags of a SPC file. It also loads the data into vSNES, so you can view the variables in the main window's APU list and the arrays in the HexViewer.
7. The Movie Editor allows the loading, viewing, editing and saving of SMV and ZMV movies. (ZMV support still incomplete.)
8. With the CHT Editor you can change the binary cheat code files of ZSNES and SNES9x.
9. The CartViewer has a second page that shows the content of the internal ROM header, just as it is stored in the ROM. It also allows selecting the correct ROM type if the automatic detection fails; this might be required to get correct HDMA table info.

There's lots of potential in vSNES, even an emulator would be possible - but that would be a bit more difficult.
