I've been using 64tass now for a couple of decades as it's an extension of Omikron Turbo Assembler from the C64. It's everything I've ever wanted in an assembler for a modern environment. Highly recommend, and everyone in my group uses it for all our projects on the C64.

This is the best 6502 assembler. Accept no substitute.

Fast and cool!

Solid assembler, with nice syntax

We've started a new retro project using the 65816. We would not be able to do much without a solid assembler.
