128 characters or 100 characters?

[HyperHandCRazy]

I was looking at the Brawlex forum and saw that
BX Clone Engine v2.0.0.0 Stable can allow 128 characters but people tell me 100 is the limit and yes I know the selecharacter is not ready to have 128 slots ready but can I use the 28 characters extra as l loadables also is it actually 128?
