All CG cutscenes are noticeably compressed and less detailed, but are still largely intact, which ended up being quite a milestone for the Nintendo 64, a system that rarely used CG cutscenes.

The audio suffered as a result, as it sounds muffled compared to the other versions.ĬG - Almost all CG made it to the Nintendo 64 version with the exception of Ada's cutscene with Annette, which was replaced with Claire's in Leon's adventure to save space (the developers were probably hoping that no one would notice!). In order to cram all the data of Resident Evil 2 onto the Nintendo 64, tons of data compression techniques were employed to reduce the game's overall data size. The Nintendo 64's sound capabilities are obviously below that of the PlayStation due to the capacity of the Nintendo 64's cartridges. Without the Expansion Pak, the game looked closer to the original PlayStation version, although it still looked a bit better. Using an N64 Expansion Pak, the increased RAM capacity allowed for the graphics to be displayed at a higher resolution than the PlayStation original.
