Graphics & Presentation
The speedrunning community maintains a specific category: "PC Original (Unmodified)." Runners use a specific version (usually the 1998 1.00 executable) without any fan patches, frame rate unlocks, or MIDI replacements. Glitches that exist in this version (like the infamous "gold saucer date skip") are patched out of later releases. final fantasy vii pc original unmodified
