A Playdate developer shares advanced C optimization techniques discovered while building a GameBoy emulator, focusing on the hardware's fast CPU but small instruction cache architecture. Key insights include prioritizing register operations over memory access and preferring -Os over -O3 to fit critical code paths within the tiny instruction cache.
Background
The Playdate is a handheld game console with a 32-bit CPU and limited cache, making low-level optimization crucial for performance-intensive applications like emulators. This discussion originated from the official Playdate developer forum.
