Abstract This paper examines designing and implementing a Magisk module to enable safe CPU/GPU overclocking on Android devices. It covers background on overclocking and Android kernel interfaces, module architecture, methods for adjusting clock frequencies and voltages, user-space controls, safety features, testing methodology, performance and power trade-offs, security and compatibility considerations, and recommendations for responsible use. 1. Introduction Overclocking boosts processor clock frequencies beyond stock settings to improve performance. On Android, kernel-level controls expose CPU clock (freqs, governors), voltage control (if available), and thermal/power limits. Magisk modules provide a systemless way to modify runtime behavior without changing the system partition, making them suitable for injecting overclocking functionality. 2. Background

This tool is used to create replacement labels for Franklin BOOKMAN cartridges that have faded or otherwise deteriorated labelling. The generated labels are downloadable as SVG files and can be printed at 100% scale for a 1:1 reproduction size suitable for application on worn ROM cards.

See the source code for this tool here.
