Another thing is, that you can try FMCB on almost all PS2-Consoles... and if you 'want more', you can install amodchip.
But tobe honest,... There isn't so much more, you can gather with a modchip.
Vice versa, FMCB extends the 'functionality' of a PS2 in various ways, regardless if a Modchip is installed.
A few features are very similar to those of modchips, like the DEV.1-Booting.
A few other features of FMCB are quite unique, like configureable button-launch, or the hacked OSDSYS.
For old modchips which have no DEV.-Mode at all, FMCB is an even better extention, because those chips still rely on booting from cdvd-drive.
...and the hacked OSDSYS, is something only FMCB offers (or a few test-elfs ).
