This is a clip during one of my mixes where I had some fun throwing in a kick drum during a hard trance build up. The volume of the incoming kick should have been louder.

This was in 1F of the JW Marriott, Minato City (Takanawa Station South Tower).

In this video, Adrian’s Digital Basement investigates the feasibility of overclocking the NES CPU. The experiment stems from the author's work with a Dendi (a PAL clone console) and a standard NTSC NES console (0:00-0:30).

Key takeaways:

• Underclocking and Overclocking: The NES CPU speed is determined by a master oscillator divided by an internal constant. By swapping CPUs between NTSC(divide by 12) and Dendi/PAL (divide by 15 or 16) hardware, Adrian creates conditions where the CPU runs at different speeds relative to the PPU (1:30-2:15, 6:15-7:00).
• Visualizing Lag: The video highlights a faulty Famicomclone that leaks internal signals to the video output. This allows the user to visualize CPU processing via diagonal lines; these lines indicate the CPU's tight loop while waiting for the NMI (Non-Maskable Interrupt). When the CPU takes too long to render a frame, these lines move off-screen, resulting in visible gameplay lag(15:40-18:25).
• Overclocking Success: When an NTSC CPU (faster) is placed into a Dendi console (which has extra scan lines in its blanking interval), the system runs at a significant overclock (~2.2 MHz). Surprisingly, many games work flawlessly, and the extra processing power effectively eliminates gameplay lag (35:15-38:30, 42:00-43:30).

Adrian concludes that while this isn't groundbreaking, it proves that hardware-level overclocking is possible. The main limitation remains that the CPU and PPU are linked to the same master clock, and changing speeds impacts sound pitch and frame timing (47:00-48:30).
