If you give me a constant name and values for each EEPROM size I can add the menu side. Code wise it is just a bunch of if macros

Ok, I'm assuming that ot os enough to add variants to the boards.txt that change: * upload.maximum_data_size=xxx (currently only 2048) * upload.maximum_size=xxx (currently only 29696) Plus something inside main.cpp so...

Great! Should we get rid of all those `#if defined` ? we're only supporting the 328p variant, right?

You ran out of flash space, maybe some library was updated and it is bulkier? By the way, 2 kb of flash are reserved for eeprom, so you could claim...

The link I posted is to a specific comment, there's what you need to do (basically upload via ISP and ignore warning. Or modify the available flash in boards.txt if...
