SED Compatibility: The tl;dr version.

The Super Everdrive  by itself will play just the non-special chip games (LIST). With a DSP-1 Chip installed (either by the seller or by yourself), it adds the capability of playing non-special chip games as well as the following DSP-1 games:

Pilotwings
Shutokō Battle '94: Keichii Tsuchiya Drift King
Shutokō Battle 2: Drift King Keichii Tsuchiya & Masaaki Bandoh
Suzuka 8 Hours
Super Air Diver 2
Super Bases Loaded 2 / Super 3D Baseball
Super F1 Circus Gaiden
Battle Racers
Korean League
Super Mario Kart
Ace o Nerae! 3D Tennis
Ballz 3D

For those who do not wish to sac a cart for the DSP-1 chip, an alternative would be to use the DSP cart you have (Super Mario Kart, for example), and use a T-CONNECTOR.

HERE IS A VIDEO EXAMPLE OF THE T-CONNECTOR WITH AN EVERDRIVE FOR DSP-1 GAMES

Other special chip games: (WILL NOT WORK ON THE SUPER EVERDRIVE!)

CX4 (Megaman X2, etc.)
DSP-2/3/4
GB-Z80 (Super Gameboy)
MX15001TFC
OBC-1 (Metal Combat)
S-DD1 (SFA2, Star Ocean)
S-RTC ( Daikaiju Monogatari II)
SA1 (Super Mario RPG)
SPC7110 (Tengai Makyou Zero, etc.)
Super FX (Star Fox, Stunt Race FX, etc.)
ST010/011/018 (Seta games)
MSU-1

It's a good start.
It might be a little confusing to newbies though. For example the wikipedia page you link to I assume is meant as an incompatibility list?
And only listing Super Mario RPG as SA1 games sounds like it's the only SA1 game.
