Doom 1 GBA Video Game Cartridge Nintendo Game Boy Advance 2001

Gameboy Advance non oem, Doom 1 video game cartridge. Game cartridge comes with a plastic protective case just like the picture shows.

The Game Boy Advance (GBA) port of Doom, developed by David A. Palmer Productions and published by Activision in 2001, is a portable adaptation of the legendary 1993 first-person shooter. It is primarily based on the Atari Jaguar engine, featuring simplified level geometry and altered content compared to the original PC version. 

Key Features and Content

• Levels and Episodes: The game includes 24 single-player levels spanning the original three episodes (Knee-Deep in the Dead, The Shores of Hell, and Inferno). While it features an episode select screen, the game plays as one continuous adventure without episode transition screens.
• Weaponry: Players have access to 8 classic weapons, including the shotgun, chaingun, rocket launcher, plasma rifle, and the powerful BFG9000.
• Multiplayer Support: Using a Game Link Cable, up to four players can compete in Deathmatch or two players can team up for Cooperative play. The GBA version includes eight exclusive deathmatch-only maps not found in other classic releases.
• Save System: Progress can only be saved between levels, with four available save slots. 

Port-Specific Quirks and Changes 

• Censorship: To obtain a "Teen" rating, several visual changes were made: blood is green instead of red, and many hellish or gory images (like impaled bodies) were removed or modified.
• Technical Compromises: To maintain performance on the handheld, monster corpses disappear shortly after being killed, and enemies are "deaf" (they do not react to sound), which can make them easier to pick off.
• Lighting Options: A "Static Lighting" mode allows players to set full brightness for all areas, which was a vital feature for the original non-backlit GBA screen.
• Sound and Music: The music tracks are slightly "shifted," with the song for one level playing on the next. 

Performance and Graphics

The port is often described as a "technological achievement" for running on the GBA hardware, though it suffers from a lower resolution and occasional frame rate drops during heavy combat. It utilizes pixel doubling (rendering at 120x160 and scaling up) to maintain playable speeds.
