Tephra Compatibility

Tephra status changes which tables and launch-control support must be supplied, so final compatibility is confirmed from the exact stable file.

Tephra V3

A customer who already has a supported V3 ROM pays the $149.99 RAL base price plus checkout fees. Installing or upgrading to V3 is optional and priced separately; it is not charged when V3 is already present.

V1 and non‑Tephra

The $199.99 RAL base price applies, plus 5% at checkout. The service includes applicable launch-control integration and editable activation, fuel, timing, RPM and speed settings. Customers may instead request a V3 upgrade, where compatible. The customer XML provides the editable settings needed for use and adjustment.

Detection mismatch

The site may show detected ROM ID, Tephra status, file size and validation status. Unknown status or a mismatch requires free source verification before checkout. Use the verified ROM ID and Tephra status to confirm the correct price.
