    Introduction

As the Ghidra open source community is growing, trying to document the new projects around Ghidra. Feel free to fork the gist and propose improvements.
CPU support


New 6502 language module for Ghidra
Atmel AVR helpers for Ghidra - ATmega328p
Processor definitions for DMG and CGB in Ghidra - Gameboy CPU (LR35902) (WiP)
ghidra based disassembly of the x68000's IPL.


## homebrew old version.txt
[From: http://hanxue-it.blogspot.com/2018/08/macos-homebrew-installing-older-version-of-software.html - just created a copy to keep it for long term]

Homebrew  always wants to install the latest version of the Formula (software). This is by design, because every time there is an update to a formula, it wants to be tested against all the other formulas that it depends on. Mixing new and old versions of software is a recipe for incompatibility disaster.

But sometimes there are situations where you need an older version of software. In my specific case, Yarn was compiled against an older version of icu4c, and I want that older version instead of recompiling Yarn.

## rop idea.txt
Full ROP explanation!

At the beginning, we predict a address were our payload will be in the end.
We can trick a bit by using a nop slide, but the payload we want execute is statically linked so we need to get rid of the nops.

For this, we build a special payload, it consists of the folllowing parts
1. a bunch of nops to nop slide. Now we just need to have a good enough guess to not hit our real code.
2. the "wiiuhaxx_loader.s". To removes the nops.
3. the size of the "real" payload
4. the real payload.

## spotifyHijack.scpt
-- Usage
--   1. Edit the settings (see below). This step is NECESSARY the first time you use it!
--   2. Run this script (this should open Audio Hijack Pro and Spotify)
--
-- NOTE: the script assumes that each track is played entirely. You CANNOT skip tracks in Spotify.
-- If you do so the script will get out of sync and the resulting files contain partial or multiple songs.
-- You can abort a recordig session by stopping this script and ending (manually) the recording
-- in Audio Hijack Pro.
--
-- You need to have "atomicparsley" installed on your system. You can install the application with
