Asar is a Super Nintendo assembler based on xkas v0.06. It's the assembler used primarily on SMW Central.
Asar's got a freespace finder, will ask for filenames if double clicked, can use parentheses and proper priority in math, can assemble SPC-700 and SuperFX codes, and has many, many other neat little features. The full list of features can be found in the manual.
New features in Asar 1.80/1.81:
Labels are allowed in assert commands
The print has a bin() function. Additionally, all of bin()/dec()/hex() take an optional argument to pad to a specified width
There is an option to emit an address-to-line mapping, which can be used by some emulators to provide source-level debugging.
New functions floor(), ceil(), bank(), datasize(), and a new <: operator.
Support for macros with a variable number of arguments
Support for global labels, which ignore the current namespace
Various internal improvements to make patching significantly faster
