Will Phi work on the newest version of Epsilon?

[empty carbon]

I'm looking into buying a Numworks calculator but I wanted to know first if it would be possible to just install Phi and Omega without any issues or if I would have to get an older version to flash onto the new calculator. The Phi and Omega wesites say it works with Epsilon 16+, but they also don't mention anything past Epsilon 18.

Also as an addition to my question, Omega adds a boot loader to the Numworks. So if you do have to install Phi using Epsilon 18, can't you just install the latest version of Epsilon after installing Omega and switch between them with the boot loader? or does Installing Epsilon 19/20 remove Phi and Omega from the device?

Phi only work with Epsilon <= 18
So to use Phi you'd need to downgrade to Epsilon 18.
But this downgrade is only possible when your calculator has been upgraded from Epsilon between 16 and 18 (excluding Epsilon 16.4.3) to Epsilon >= 19.
So if you buy a N0110, it will come with Epsilon 20 already installed, preventing the downgrade.
(This is considering you get a N0110, which isn't guaranteed, because the new N0120 is starting to spread on the market. The N0120 has no custom firmware available for it currectly)

But if you do get the Omega bootloader on your (N0110) calculator, it is possible to dualboot: https://discord.com/channels/663420259851567114/1088891663834951770
