Resident Evil 0 was always meant to be larger than RE2 . The "Partner Zapping" system meant assets had to be duplicated for two characters on screen simultaneously. The GameCube version eventually shipped on a 1.5GB mini-DVD. The N64’s largest cartridges maxed out at 64MB (512 megabits). Even with the wizardry of Factor 5 (who handled the RE2 N64 port), squeezing RE0 onto a cartridge required sacrificing bones, music, and background fidelity.
