retrodisasm v0.3.0 released (formerly nesgodisasm)

A tracing disassembler for retro systems that generates assembly source you can reassemble back to the original ROM exactly.

The rename reflects its evolution beyond just NES - now supporting CHIP-8 as well, with more systems planned.

@PinoBatch cool! I wrote a little tool that can create perler bead patterns of an image with features like resizing and color matching: https://github.com/cornelk/beadmachine

My new modular assembler is named retroasm. For the first version it will support asm6 features/syntax and generating 6502 CPU code for NES.
The current directives in progress to support are ORG, ALIGN and FILLVALUE.

The work on the next tool has begun: a new assembler for NES. The goal is to be compatible to the syntax of different commonly used assemblers like asm6 and ca65.

v0.2.0 of a new NES ROM tracing disassembler is released, now includes support for code/data logs, bugfixes and a jump engine detection.
It was tested on all official US NROM games and creates an .asm file that can be assembled back to the exact same ROM image:

@gauauu oh, this is the first jump engine that I found that not just uses generated code but also different tables for low and high bytes of the function addresses. Unlucky first choice :)

With procedural generation you can save a lot of space for content but did you know that Pitfall! on the Atari 2600 uses one byte (!) to describe a room? Here's the link to an article describing how that works:
