JP1 Remotes

With no luck in the Code search section

I am seeking to make an upgrade for said stereo.

This is what I know about the stereo:

Made in August 1997, in Malaysia
The micro inside is an NEC mask programmed chip, it runs all of the CD, audio controls, and tuner functions.
A wild guess is other RP798x IR stereos might use the same remote.
It is an AM/FM/CD/Cassette portable/bookshelf stereo.

I would like to know where to start in finding the protocol/device, at least what protocol is used.

I don't want to manually cycle through a handful of protocols, a number of device addresses each protocol, and 256 EFCs each protocol/address.
