Belt Speed Tuner

Set the default speed of each belt tier exactly how you like it — in plain items per second, with one slider per tier. No more guessing at engine units.

Features

• One slider per tier: yellow, red, blue and turbo (Space Age).
• Values are in items per second, the number you actually see in-game.
• Each tier's belt, underground belt and splitter are kept in sync, so nothing becomes a hidden bottleneck.
• Defaults match vanilla (15 / 30 / 45 / 60), so installing changes nothing until you tweak it.
• Fully localised in English and French.

Settings (Startup → Mod settings)

• Yellow belt speed — default 15 items/s.
• Red belt speed — default 30 items/s.
• Blue belt speed — default 45 items/s.
• Turbo belt speed (Space Age) — default 60 items/s.

Notes

• The turbo tier only exists with Space Age; the setting is harmless without it.
• This mod targets the vanilla belt tiers by name. If you use belts added by other mods, let me know and a global-multiplier mode can be added.
