KB10013: Nintendo Console Models Compared – NES through GameCube

Nintendo produced some of the most iconic and enduring gaming hardware in history. From the 8-bit NES through the GameCube era, each generation brought significant technological advances. This article covers the major home consoles and handhelds, including hardware revisions that collectors should know about.

Home Consoles

Famicom / NES (1983 / 1985)

The Nintendo Entertainment System (known as the Famicom in Japan) revived the home console market after the 1983 crash. It uses a Ricoh 2A03 CPU—a modified MOS 6502 running at 1.79 MHz (NTSC) or 1.66 MHz (PAL)—with a built-in programmable sound generator providing two pulse wave channels, a triangle wave, a noise channel, and a delta modulation channel for sample playback. The PPU (Picture Processing Unit, Ricoh 2C02) produces a 256×240 display with up to 25 colors on screen from a 54-color palette, with hardware support for 64 sprites (8 per scanline). The system has 2 KB of internal RAM and 2 KB of video RAM.

Famicom (HVC-001, 1983)

The Japanese original is a compact red-and-white unit with hardwired controllers (the second controller includes a microphone), a flip-top cartridge slot using a 60-pin connector, and RF output only. An expansion port on the front allowed accessories like the Famicom Disk System, which added rewritable disk-based storage.

NES Front Loader (NES-001, 1985)

The North American NES was completely redesigned to resemble a VCR, deliberately distancing it from the "video game" stigma of the crash era. It features a front-loading cartridge mechanism with a 72-pin Zero Insertion Force (ZIF) connector, detachable controllers, composite and RF video output, and a bottom expansion port. The front-loading design, while initially clever, is the NES's biggest reliability weakness—the ZIF connector's spring-loaded pins bend over time, leading to the infamous blinking screen and the "blow on the cartridge" ritual. The NES went through at least ten internal motherboard revisions (NES-CPU-01 through NES-CPU-11).

NES Top Loader (NES-101, 1993)

Released after the SNES launch, the redesigned "top-loader" NES is a compact, rounded unit with a top-loading 72-pin cartridge slot that eliminates the ZIF connector's reliability problems. It also removed the CIC lockout chip (ending the blinking power light issue) and the expansion port. However, most NES-101 units only output RF video (no composite), and some exhibit visible vertical lines (referred to as "jailbars") in the image. A rare AV-modified revision (NESN-CPU-AV-01) does include composite output.

Super Famicom / SNES (1990 / 1991)

The Super Nintendo Entertainment System moved to a 16-bit architecture. The CPU is a Ricoh 5A22, a 65C816-based processor running at 3.58 MHz (with bus speeds of 2.68 or 1.79 MHz depending on the operation). It has 128 KB of main RAM. The graphics subsystem uses two PPU chips capable of up to 256×224 resolution (256×239 in some modes), 256 colors on screen from a 32,768-color palette, Mode 7 rotation and scaling effects, and up to 128 sprites. The sound system is a Sony SPC700 processor with a dedicated 64 KB of audio RAM driving an 8-channel ADPCM DSP capable of sophisticated sampled audio. Some game cartridges included enhancement chips (such as the Super FX for 3D polygon rendering) that supplemented the base hardware.

SNES Revisions

The original SNES (SNS-001 in North America, SHVC-001 in Japan) went through several motherboard revisions. A significant late revision is the "1CHIP" model, which consolidated the two separate PPU chips and the CPU into a single package. The 1CHIP models are prized by collectors for their notably sharper RGB video output with less color bleed. The SNS-101 (1997) was a compact, budget-friendly redesign that removed the expansion port and the eject button; it also uses the 1CHIP design and produces excellent video quality, though it lacks S-Video output without modification.

Nintendo 64 (1996)

The N64 was Nintendo's first fully 3D-focused console. It uses a MIPS R4300i-based NEC VR4300 CPU at 93.75 MHz and a custom SGI Reality Co-Processor (RCP) for graphics and audio. The RCP contains the Reality Signal Processor (RSP) for geometry and audio processing and the Reality Display Processor (RDP) for pixel rendering, capable of Z-buffering, anti-aliasing, and texture mapping. The system has 4 MB of unified Rambus DRAM, expandable to 8 MB with the Expansion Pak (required by some later games like Donkey Kong 64 and Majora's Mask). It was the last major home console to use cartridges, which provided fast load times but limited storage capacity and increased manufacturing costs compared to CD-ROM.

N64 Revisions

The N64 had one external design but six known internal motherboard revisions (NUS-CPU-01 through NUS-CPU-09, not all sequential). Early revisions (NUS-CPU-01 through NUS-CPU-04) are preferred by modders because they support easier RGB modification. Later revisions changed the video encoder and modified the expansion port design. The controller featured the first analog thumbstick on a major console controller, along with an expansion port for the Rumble Pak, Controller Pak (memory card), and Transfer Pak.

Nintendo GameCube (2001)

The GameCube was Nintendo's first disc-based console, using proprietary 8 cm mini-DVDs holding approximately 1.5 GB each. The CPU is an IBM "Gekko" PowerPC 750-derived processor at 485 MHz. The GPU is an ATI/ArtX "Flipper" at 162 MHz handling geometry, lighting, and pixel processing with support for hardware texture compression, multi-texturing, and bump mapping. The system has 24 MB of main RAM (1T-SRAM) and 16 MB of auxiliary RAM (DRAM). It features four controller ports and two memory card slots. The GameCube also introduced the Game Boy Player accessory, enabling Game Boy, Game Boy Color, and Game Boy Advance cartridges to be played on a television. Later "DOL-101" revisions removed the digital A/V output port, which limits compatibility with high-quality component video cables that are now highly sought after.

Handhelds

Game Boy (DMG-01, 1989)

The original Game Boy used a Sharp SM83 CPU (often described as a modified Z80/8080 hybrid) at 4.19 MHz with 8 KB of work RAM and 8 KB of video RAM. The screen was a 160×144 pixel reflective LCD displaying four shades of green. Audio featured four channels: two pulse waves, one programmable waveform, and one noise channel with stereo output through headphones. Powered by four AA batteries for approximately 15–30 hours of play, its exceptional battery life and portable form factor helped it outsell every competitor despite inferior screen technology. The Game Boy Pocket (MGB-001, 1996) was a slimmer redesign with an improved screen (true grayscale instead of green), running on two AAA batteries. The Game Boy Light (MGB-101, 1998) was a Japan-only variant with an electroluminescent backlit screen.

Game Boy Color (CGB-001, 1998)

The Game Boy Color doubled the CPU speed to 8.39 MHz (switchable to the original speed for backward compatibility), quadrupled the work RAM to 32 KB, doubled the video RAM to 16 KB, and added a color screen displaying up to 56 simultaneous colors from a 32,768-color palette. It was backward-compatible with the entire original Game Boy library, adding basic colorization to older games via predefined palettes. The form factor was similar to the Game Boy Pocket.

Game Boy Advance (AGB-001, 2001)

A major generational leap, the GBA used a 32-bit ARM7TDMI processor at 16.78 MHz alongside the original Game Boy's Z80-derived CPU for backward compatibility. It had 32 KB of internal RAM, 256 KB of external RAM, and 96 KB of video RAM. The screen was a 240×160 pixel reflective TFT LCD capable of displaying 32,768 colors. It could produce graphics roughly comparable to the SNES, with Mode 7–style rotation and scaling built in. The GBA SP (AGS-001, 2003) introduced a clamshell design with a front-lit screen and rechargeable battery. A later SP revision (AGS-101, 2005) upgraded to a true backlit screen and is highly sought after by collectors for its excellent display quality. The Game Boy Micro (OXY-001, 2005) was a tiny redesign that dropped backward compatibility with Game Boy and Game Boy Color cartridges.

Collector and Restoration Notes

The NES front-loader's 72-pin connector is the most common repair, with aftermarket replacements and boiling/bending of original pins both being popular fixes. Cartridge contacts on all systems benefit from cleaning with isopropyl alcohol. SNES units can develop yellowing of the plastic (especially the North American "Super NES" model), which is cosmetic but can be reversed with retrobright treatments. N64 analog sticks wear out over time as the plastic stick grinds down internally; replacement stick modules are widely available. Game Boy screens can develop vertical or horizontal dead lines, which can sometimes be repaired with careful resoldering of the ribbon cable connections. GameCube laser assemblies can weaken and may need potentiometer adjustment or replacement. For all systems, cartridge-based games are generally very reliable, but battery-backed save game cartridges (common on NES, SNES, and Game Boy) will eventually need their internal CR2032 or CR1616 batteries replaced.
