Beginning with the fifth generation of consoles, which introduced more powerful hardware and 3D graphics, developers had the ability to output at full PAL resolution without borders or stretching, although games still typically ran slower and all ran at 50 Hz. Beginning with the Dreamcast and continuing through the sixth generation of consoles, developers began including PAL60 modes in their games. Games that run at PAL60 are produced with the same colour encoding system as 50 Hz PAL signals, but with the NTSC resolution and field rate of 60 Hz, providing an identical gaming experience to their NTSC counterparts, however some games, such as Tekken 4 and Tekken 5, will actually use the NTSC colour mode when in 60Hz mode; these games will appear in black and white on PAL-only televisions.
