Laserdisc Player Conversion/Replacement - The Pioneer LD-V1001/LD-V1000 laserdisc players are not natively compatible with any other model for a direct substitution.
As of August 2023 - Although no aftermarket laserdisc player conversion/replacement products have officially announced their compatibility with GP World, the Dexter board, which has not been tested with GP World, should be presumed to work.
