Welcome to our our page dedicated to the hardware topics related to reverse engineering! This page serves two roles. It groups all of our posts related to physical Hardware, and it aggregates high quality sources from the web into create a unified reference.
This section collects the main topics related to the general hardware components that are used in game consoles and development kits.
A game console itself is a series of chips placed on to a board, however unlike a PC motherboard it contains specialist chips that can normally not be upgraded.
The placement of the chips on the board is called the hardware architecture and it is an art as much as a science, it needs to be carefully crafted to get the most performance out of the system.
It also needs to implement anti-piracy measures, which is why many systems required a physical mod-chip installed in order to by pass copy-protection or region-lock.
Knowing the hardware is vital for understanding why a game was written the way it was, game programming is not easy and developers wanted to get the most out of the hardware.
This resulted in them having to write strange code in order for the hardware to be pushed to the limits. It’s this attention to hardware detail which makes developing an emulator a very tricky task and results in some games being unplayable or missing certain features.
This section tracks the key CPUs that defined each console generation, from simple 8-bit designs to richer 16/32-bit hybrids. Knowing their instruction sets, bus layouts, and quirks is essential for emulation, tooling, and reverse engineering hardware behavior.
Released by MOS Technology in 1975, the 6502 was designed as an affordable alternative to the more expensive microprocessors of its time. It was used in the Nintendo Entertainment System, Atari 2600, Commodore 64 and many others. We have a specific post all about is here:
Motorola’s 68K family powered a generation of consoles and computers thanks to its clean CISC design and generous register set. It was famously used in the Sega Genesis/Mega Drive, Atari ST, and early Macintosh systems, we have a specific post all about is here:
The PowerPC was a collaboration between Apple, IBM, and Motorola, custom PowerPC chips used in the Nintendo GameCube (Gekko), Wii (Broadway), Xbox 360, and PlayStation 3.
We have all our Game Console Development Kit Hardware posts categorised from a single page, acting as a central hub for understanding the specialized hardware used to create video games:
gameranx has an excellent video documenting the architectural evolution of Sony’s console line from 1995 to 2013. It details key hardware transitions, including the PS1’s dedicated 3D processing, the PS2’s Emotion Engine and DVD integration, the PS3’s complex Cell Broadband Engine with Blu-ray support, and the PS4’s shift to a developer-friendly x86-64 APU with unified GDDR5 memory.
Dmitry.GR has an excellent write up about reverse engineering the Fisher-Price Pixter Color to run PalmOS 5. It covers the challenges of the device’s minimal Sharp LH75411 ARM7 SoC (lacking cache and MMU), creating a custom cartridge for code execution, and optimizing performance for the hardware’s slow memory bus and STN display.
