PAL The following countries no longer use PAL for terrestrial broadcasts, and are in process of converting from PAL (cable) to DVB-T or ISDB-T. 60 Hz operation During the mid-1990s, the practice of modifying consoles such as the Super NES and Mega Drive to allow 60 Hz operation became somewhat common among PAL gamers, due to the rise in NTSC/60 Hz capable PAL TVs and the relatively simple nature of the modifications. Beginning with the Amiga CD32, which introduced more powerful hardware, 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 60 Hz mode; these games will appear in black and white on PAL-only televisions. The Brazilian PAL-M standard always operates at 60 Hz. Criticism of PAL region video games Games ported to PAL have historically been known for having game speed and frame rates inferior to their NTSC counterparts. Since the NTSC standard is 60 fields/30 frames per second but PAL is 50 fields/25 frames per second, games were typically slowed by approximately 16.7% in order to avoid timing problems or unfeasible code changes. Full motion video rendered and encoded at 30 frames per second by the Japanese/US (NTSC) developers was often down-sampled to 25 frames per second or considered to be 50 frames per second video for PAL release—usually by means of 3:2 pull-down, resulting in motion judder. In addition to this, PAL's increased resolution was not utilised during conversion, creating a pseudo letterbox effect with borders top and bottom, which looks similar to a 14:9 letterbox, and leaving the graphics with a slightly squashed look due to an incorrect aspect ratio caused by the borders. This was prevalent in previous generations (especially during the 8-bit and 16-bit era, when 2D graphics were the norm at that time). The gameplay of many games with an emphasis on speed, such as the original Sonic the
