NAOMI TSOPs

Does anyone know if the TSOP48's MASKs used in some NAOMI carts have an equivelant pinout or is it a custom job?

Thanks

Thats all its got on it.
Im guessing its not a standard pinout and that there is no direct replacement available should this prove to be dead but its always worth a try aint it
