Which PAL games were the first to feature 60Hz modes?

[dreamcaster]

I've noticed that the earliest game I've got that supports a 60Hz mode, is Sonic Adventure for Dreamcast.

Was there anything before this - or was the Dreamcast the first console to offer games with the 60Hz feature?

i'm pretty sure they even advertised with saying they are the first console to officially support 60Hz, yes

The first games with a 60Hz option were indeed for the Dreamcast (although most launch titles and sloppily-programmed later games are just 50Hz).
However, I believe the PAL NeoGeo system came originally in two flavours, 50Hz & 60Hz, so once again SNK gets there first.
