The developer has stated that with continued optimization, the full original Tomb Raider game could potentially fit within a 32-megabyte GBA ROM cartridge. This makes it a significant project for both Tomb Raider fans and homebrew enthusiasts alike.

Once compiled, you can load the ROM using two primary methods:

The Game Boy Advance (GBA) is famous for its 2D sprite-based library, making the appearance of a fully 3D game on the system feel like modern sorcery. Thanks to an open-source project called OpenLara, gamers can now experience the original 1996 Tomb Raider on Nintendo’s iconic 32-bit handheld. This engine rewrite pushes the GBA to its absolute limits, delivering a smooth, fully 3D rendering of Lara Croft’s earliest adventures.
The GBA’s small screen can make distant ledges hard to see. Hardware Strain: The developer has stated that with continued optimization,
The GBA port has consistently garnered attention from major outlets. It was featured on Kotaku as "Someone Got PS1 Classic Tomb Raider Running On A Game Boy Advance," called an "impossible port" by Modern Vintage Gamer, and described as "perhaps some of the best-looking 3D ever shown on the system" by Nintendo Life. XProger himself explained that when he first released a tech demo a year prior, he was not sure the GBA was even capable of running such a game, but persistent optimizations led to the remarkable alpha seen today.
Classic maps like Peru (Caves, Vilcabamba) are fully explorable.

A standard GBA cartridge maxes out at 32MB. Because of this space restriction, the entire game cannot fit onto a single ROM with full audio. The project is often split into separate ROMs for different levels or requires heavily compressed assets. The Verdict: A Technical Marvel
The original Tomb Raider was built for the PlayStation, Sega Saturn, and MS-DOS PCs—systems featuring dedicated 3D geometry pipelines or significantly faster central processors. The GBA possesses no built-in 3D hardware acceleration. It relies on a 16.78 MHz ARM7TDMI processor to calculate visuals.
This project isn't just a novelty; it's a celebration of what talented developers can do when they push aging hardware to its absolute limits.
Here is everything you need to know about the OpenLara GBA ROM, how it works, and how to play it. What is OpenLara?
The OpenLara GBA port is a love letter to both Tomb Raider and the GBA homebrew community. It proves that with clever optimization (fixed-point math, software rasterization, and tile-based rendering tricks), even a 2001 handheld can run a real-time 3D action-adventure game originally designed for Pentium-class PCs.
