Pika Macro ASsembler

A simple 2-pass assembler with a customizable instruction set.

Please note that this is something of a restoration project. PMAS is not really intended to be the future of Pokémon mini homebrew going forward. Please check out the official Epson utilities or Skiploom instead.

Executables

• pmas - Assembler
• pmdis - Disassembler

Further information

• cpu/minx - The original MindX-based instruction set, from back when we called the PM code MinX
• cpu/s1c88 - The official Epson S1C88 instruction set
• cpu/pm - A combination of the above two syntaxes
• cpu/r16 - Some other instruction set DarkFader left here
• cpu/*/readme.s - A quick reference of directives and required syntax

About

PMAS was originally designed by Rafael Vuijk (DarkFader) of darkfader.net but he's essentially disappeared so now it's maintained by the pokemon-mini.net community.

The final official release version was 0.15 (built) and 0.19 (source).
