different loader types

[silentpanda]

i am new to the cube scene -

ok, so i have been reading the posts, and i have a question about loaders.

there is the starcube beta loader and then there is phoenix and then there is PSO and PSOL and such.

what is the difference - can they all be used in combination - are they, as the name states, just for loading home brew - or do they work for uploading and backuping -

any pointing to a direction would be helpful
thanks -
