Casio Calculators / Should I update the firmware?
« on: July 10, 2018, 12:47:24 pm »

I've recently bought a CG20 as my first ever programmable calculator (I hear somebody whispering that you should have bought an HP or a TI). Preloaded firmware version is 02.02.0201.

I'm planning to learn to program it using the community SDK. I wonder, does updating it break any of the programming methods currently known? Also, is it possible to 'downgrade' the firmware? (e.g. load older firmware versions)
