Early PC games that needed nearly cycle-accurate timing relied on the "turbo button" on the front panel of early XT and AT models that clocked the system back down to 4.8 MHz. I'm sure a commercialized version of such an NES OC mod would have a button to disable it for games that use cycle-timed effects.
Hard to tell. Because the Super NES had hblank-triggered DMA, fewer Super NES games relied as heavily on cycle-timed code. For another thing, the 65c816 ran asynchronously from the . But back in Super NES days, ROMs that could respond at 3.6 MHz were expensive, and a lot of games ran from slow memory (at 2.4 MHz or 2.7 MHz or something like that) to get replication costs down.Great Hierophant wrote:I wonder what an overclocking mod for the SNES, which had a notoriously slow 65816, would do?
The WDC 65c816 was as fast as the memory. The Sega Genesis's MC68000 ran much slower than the memory, with a lot of so-called "internal operation" cycles.At least the NES had a clock speed on par with the consoles of its day.
