: Features impressive textured 3D environments. It uses GBA "Mode 4" for rendering, though developers have experimented with other modes for potential gains. Playability
Since downloading a pre-made ROM is legally dubious, here is the legitimate guide to building your own using the open-source code.
The OpenLara engine theoretically supports TR2 and TR3 assets, but the GBA port is currently limited to the first game due to memory constraints. The PC version of OpenLara can run all classic titles.

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 current alpha release features the first three levels of the game.
Because the GBA possesses no dedicated 3D graphics hardware, every single polygon must be drawn via software. The engine uses a custom scanline rasterizer optimized in ARM assembly language to push the handheld's 16-bit CPU to its absolute limits. Room-Based Culling
However, the moment you combine the OpenLara engine with the LEVEL.PHD file from Tomb Raider , you are creating a derivative work. If you own the original PC disc, many would argue this falls under "fair use" for personal archival and format shifting. But distributing that combined file as a "OpenLara GBA ROM" is software piracy. : Features impressive textured 3D environments
