Shows effective CPU speed for Sega Genesis and for Sega CD, if attached.
Usable for checking overclocking in emulators and hardware.
Cpu speed affected by dram refresh cycles and other stuff [like 2 cpu access one area at once] and differs by areas where’s code executed. This areas can be changed by buttons. On real hardware it’s possible to execute code from the sega-cd registers area without ram refreshing effect to see real clock speed.
This test shows: Main-cpu M68000 cycles per second, Z80, Sub-cpu 68000 if sega-cd is connected, and for gfx asic pixels per second approximately. Shows 68010 for modded with 68010 cpu consoles.
Test counts for real cycles, but maybe not 100% accurate +- for several 10’s Hz. If you know the difference with the real frequency, you can try to send me a message.
