[1.0.1] - 2026-10-18

A new body. Driving, controls, sounds, settings and handling are the same as 1.0.0: only the car's model file changes, and its size, weight, collision, wheels and two seats stay as they were.

Changed

[1.0.0] - 2026-10-18

First public release.

Added

• Roadster X, an add-on car (roadsterx) for GTA IV: The Complete Edition 1.2.0.59. No stock car is replaced.
• Two-seat cabin with butterfly doors: the driver and one passenger.
• Jump: tap to hop over traffic; hold to keep rising, so the hold sets the height, then let go to drop onto the soft landing.
• Hover and fly on ten cold-gas thrusters: double-tap to hover, then climb (jump button, accelerator, or look up to climb straight up), descend, travel and boost. Double-tap again to drop; the thrusters catch the car just above the ground. In the air, one press of the jump button fires the jets again.
• Air tricks (flips, rolls, spins), kickflips on the road, and quick 180 and 360 spins.
• Soft landings for jumps, ramp jumps and ledge drops.
• Turn smoothly on the spot from a standstill (push further to turn faster), and powered drifts when moving.
• Active rear wing (Auto, Downforce, Airbrake, Stowed) and speed-scaled downforce with fan suction.
• Water rescue: the thrusters lift the car back out of water (can be turned off).
• On-screen systems panel with gauges and the controls that matter right now.
• Original synthesized sounds: thrusters, wing servo, doors and motor.
• Every setting in plugins/RoadsterX.ini, reloadable while you play.

Known issues

• One passenger only (it's a two-seater), and companions can take a moment at the butterfly doors.
• Developed and tested on a Mac with CrossOver. Windows should behave the same; please report anything that doesn't.
