But the big thing that keeps biting us bites us again: the increased line rate means less time for mid-scanline effects, and less code that can run on a scanline. The OTL Atari 2600 has 76 cycles per scanline, derived from its 1.19MHz clock and a linerate slightly off from the spec 15.734kHz. The ATL’s higher line rate drops that budget down to about 40, and then even lower if you drop to a 1MHz clock. And now consider what the 2600’s dot clock is, 3 times the cycle clock. Those are some even chunkier pixels, and remember, the achievable resolution of the 2600 is much lower due to sprite and playfield pixels being wider than the dot clock. We might not need that extra playfield register.。关于这个话题，新收录的资料提供了深入分析
