Version 2.5.2
The 6502.Net Macro Assembler is a simple cross-assembler targeting several CPUs from the 8-bit era of computing including the MOS 6502 and its variants, the Motorola M6800 and M6809, and the Zilog Z80. It has several advanced features, such as conditional assembly, macros and custom defined fuctions. With the aim of cross-platform compatibility, it is targeted for .Net Core 3.1.
