Meaning of いいなり


What is the meaning of いいなり in the phrase

> セーブするにはポケモンレポートこまめにかくといいなり




It appears this character is using なり, an old copula roughly equivalent to だ
or です in the modern day, as just something they say at the end of their
sentences to give them an 'old' feel. なり did not follow し adjectives, the
precursor to い adjectives, as し could stand on its own. かくとよし would be
equivalent to かくといいです or かくといいよ (though I'm not sure if the と conditional was
used at the time)
