The exact value of a capacitor may be hard to guess beforehand, but the ratio of two or more capacitor values on the same chip will be very precise. Many differences can affect the absolute value, so designs try not to count on exact values or, if they do, resort to things like laser trimming or other tricks.Ĭapacitors, however, are different. He points out how resistors are notoriously hard to build accurately on a production IC. explanation of how transistors, resistors, and capacitors appear on the die are helpfully illustrated with photomicrographs. If you know his work, you won’t be surprised to find out the comparison included stripping the die out of the IC packaging. People have noticed before that the Game Boy Color sounds very different than a classic Game Boy, and he wanted to find out why. His topic this time? Comparing two Game Boy audio chips. We always look forward to a new blog post by and this latest one didn’t cure us of that.
#GAMEBOY COLOR EMULATOR CHIP SOFTWARE#
Posted in Games, Software Development, Software Hacks Tagged emulator, gameboy, gameboy color If you’re interested in a deep dive into the audio chips inside a Gameboy Color, has already done the research for you. The only feature that’s noticeably absent is sound, which would require a significant amount of code to emulate properly. We love the idea of implementing each opcode one by one and gradually seeing the emulator make it farther and farther through the ROM.

goes through a detailed listing of each opcode of the processor, memory, the graphics unit (PPU), and how it interacts with a modern operating system. All the code for pokegb can be found on GitHub. There is also an obfuscated version that comes in at just 68 lines and in the shape of three Pokeballs.
#GAMEBOY COLOR EMULATOR CHIP FULL#
What’s perhaps even more amazing is that this full emulator is just 582 lines of C++ (using SDL for graphics and input). While this emulator could play other GameBoy games, the way it was implemented was to support only the opcodes and features that Pokemon Blue used. The game is, of course, the popular blue edition of Pokemon. Had previously implemented a GameBoy Color emulator but decided to make a new emulator that to play just one game called pokegb.
