Pros
Pro "Compatible" with most games
ZSNES has been in development since the 90's, and in that time has been fixed to run the vast majority of SNES games smoothly.
Due to it's "accuracy", it can run roms that most other emulators would break. Not because the emulation is broken, but because the roms are broken.
Pro Fast playback of ROMs
ZSNES is hand-optimized for x86, so it will run incredibly smoothly even on older computers.
Pro Built-in video capture
Gameplay can be recorded and saved as both raw or lossy files. Quality settings can be tweaked in zmovie.cfg file.
Pro Games can be saved at any point
Pro Multiplayer support
Games can be played with other people over TCP/IP network.
Pro Built-in support for cheat codes
ZSNES supports Game Genie, Pro Action Replay, and GoldFinger cheat codes.
Pro Built-in audio capture
Game audio can be saved to a .spc file.
Pro Can speed-up and rewind games
Pro Runs well even on weaker hardware
Pro Engaging and motivated community
Teeworlds' one-of-a-kind community is the thing keeping the game alive. Be it the community servers or maps or all the other innovative content.
Pro Easy to pick up but hard to master
You will never stop learning new tricks while playing Teeworlds, no matter how long you play. At the same time it's easy for new players to just pick it up and have a blast.
Pro Available from Steam and in Linux distributions
So it's easy to play cross-platform with friends.
Pro Tons of mods and maps
Pro Very fun and engaging gameplay
Even at relatively low skill levels the game is a lot of fun - think Worms in Realtime! The antics you can get up to while "hooking" yourself around maps is just silly :P.
Pro Very pretty
Pro Very intuitive
Easy to install and use.
Pro Usually populated servers
Cons
Con Laughably out of date
Not only was it abandoned over 10 years ago, the strides that other emulators have made in the same time is astounding.
Con Inaccurate compared to competition
ZSNES sacrifices emulation accuracy for speed (relative to e.g. Higan emulator). Sound emulation is a particularly large weakness.
Con Abandoned
While no official statement on discontinuing the software was made, last progress update was posted in 2007 and now seems highly unlikely that any further updates should be expected.
Con Weird net-code
Even though the game is playable without issues and characters move like they should, they don't register enemies' mouse movements really well. Because of that, it's hard to tell apart who is a spinbotter and who's a legit pro player.
