The N64 port of Resident Evil 2 achieved a remarkable 165:1 compression ratio to fit 15 minutes of FMV cutscenes into 24 MB, down from 4 GB uncompressed. Angel Studios developers repurposed the N64's Reality Signal Processor for video decompression, upscaling, and frame interpolation, while using chroma subsampling and DMA transfers to overcome hardware limitations. The port leveraged the N64's programmable RSP and Factor 5's MusyX audio tools, demonstrating creative problem-solving in constrained environments.
