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.

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:

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:

Pinball for NES uses an interesting jump engine, it writes the opcode 4c for an absolute jump followed by the destination address and then calls into the generated code:

lda a:$DB74,X
sta z:$E4
lda a:$DB7e,X
sta z:$E5
lda #$4C
sta z:$E3
jsr $00E3
