Paul’s Tech Talk – LSDJ 5.3.5_4x Part 2: Sandpaper vs Eardrums

Hello all and thank you for reading Paul’s Tech Talk on The ChipWIN Blog!

This article is the second part of an issue on the spicy topic of PSG Chip Overclocking. In the first part, we tackled the basic theory behind what overclocking could achieve on an NES when ticks sped up enough to reach into the audio range. Today, we’re going to try and be more specific, and try out some practical examples on Gameboy.

While audio range speeds can be achieved at high tempos on stock LSDJ, we’re going to try and venture beyond that, thanks to the very unique test build of LSDJ: 5.3.5_4x, which multiplies tempo by FOUR.

Let’s dive in!

Hello beautiful people and thank you for reading Paul’s Tech Talk on The ChipWIN Blog!

Today we’re going to talk about a very special version of LSDJ, and a tracking method that cannot often be used on Gameboy, but flourishes on other platforms such as NES: ~ OVERCLOCKING ~ ♪♫

During the avalanche of updates that gave light to this column in the first place, the community was hard at work trying to sniff out bugs and offer feature suggestions of their own. Some were very daring, seemed almost impossible, but were still considered by Johan for integration. One of them was actually the notion of underclocking. Why make the gameboy even slower than it is, you will undoubtedly ask? Well there is one limitation of the Gameboy hardware that theoretically could have been overcome with this method: its note range.
