ROM Hack Request: Zelda TotK extended or infinite vehicle timer

[falcorr]

Vehicles / parts stay activated a limited amount of time before flashing green then expiring and disappearing. I think there's room for more convenience without breaking map design.

Edit: A mod now exists. Not sure if allowed to link to the domain.

Is it already done?
I'd love to have non-expiring missiles to attach them to my shield! Of course they'll spend battery (or even if they don't)
Would you share a "tip" to find it? If not the full URL...
