It is the summer of TMNT, and here is another Behind the Code video for the first entry on the NES. This video focuses on the application of gravity with respect to frame rate for jumping in the game and also breaks down the frame timing for making the three types of jumps – short, […]
I thought it would be fun to dig my nails into the code of Teenage Mutant Ninja Turtles for NES – a popular game that seems rather rushed. No surprises – the code is sloppy in more ways than one. Swimming, water current, that infamous Seaweed Screen of Doom, and some weird collision problems on […]
Recently Krikzz posted a new “core” for the Everdrive 64 X5 and X7 rom carts that replaces the Neon emulator for NES emulation on the Nintendo 64. This update uses the FPGA in the newer Everdrive 64 carts with the goal of getting a more cycle accurate experience than what the Neon emulator could provide. […]
Krikzz has just released a new firmware update for the EverDrive N8-Pro rom-cart. In this new update, Krikzz added support for yet another NES/Famicom mapper. For the uninitiated, mappers refer to the different hardware configurations used in some NES/Famicom carts to bypass the console’s limitations. Some of the most common uses of mappers include: extra […]
Krikzz just released a new NES core, specifically developed to run on the EverDrive-64 X series of rom carts. NES emulation on N64 is not new as Neon64, an open-source NES software emulator for the N64, has been available for years now. While early revisions of Neon64 suffered from game compatibility, audio, and lag issues, […]
The latest video in the Behind the Code series features a look into the logic that drives Quick Man in Mega Man 2 for the NES. His behavior is a good example of code that somehow manages to work despite numerous bugs being present! I made a few code changes to correct these bugs and […]
If you are into NES games these days, you’ve probably heard the of term “mapper.” While the details of the various chips used in NES cartridges are just a quick Google search away, a few of their abilities were mentioned in Volume 20 of Nintendo Power back in 1991! I thought it might be fun […]
Hello, RetroRGB! Chris from Displaced Gamers here. I’ve released a new video that focuses on the basics of NES scrolling and uses Super Mario Bros. as an example. While doing research for this project, I found many new NES developers struggled a little bit when it came to understanding Nametables and Mirroring. This video makes […]
The Nintendo NES was a strange beast when it came to how it generated a video signal. Most other retro video game systems generated colour information internally (and often externally) in a combination of well defined red, green and blue values and then later combine or converted them into various broadcast signals like composite video, […]
A modding group has released a Mesen HD Pack based on the Zelda 1 Redux patch that adds remastered audio and graphics to The Legend of Zelda: This remaster is a pretty extensive overhaul of the original game and looks terrific in this video. While I know a lot of enthusiasts prefer to enjoy games in their […]
