Unique graphics. Giant sprites. No flicker. How on earth does this game work? The MMC2 chip contained in Punch-Out’s cartridge allows the NES to switch between two pairs of tiles for each half of the pattern table. While the MMC1 already allows bank switching for graphics, the MMC2 allows the switch to happen in the […]
Punch-Out!! has been on my list of games to investigate for a long time, and I finally have something to show after a crazy amount of research. This video covers how opponent data is used to determine where to branch and what to do in code, how to manipulate boxer behavior, secrets that you will […]
In December of 2019 after many years of runs, the speedrunning record for Castlevania on the NES was close to 11 minutes 24 seconds. In Summer of 2020, speedrunners took a new discovery for the implementation of scrolling for the game and used it to skip several screens at a time in various places throughout […]
RetroRGB gets down to business when it comes to measuring lag. That new wireless controller or fancy display might seem cool on paper, but what about performance? Modern devices and emulation of retro games can add to lag, but lag begins with the game code itself. Let’s hop into the execution time for standing attack […]
The developers at ENDURR Technologies have announced an internal BlueRetro mod that will allow for low-lag Bluetooth controller connectivity to the original NES. Preorders were announced to go live later this month on the APE Industries site. Developer Aaron Peckler (@Beardanidas) shared that the kit will be compatible with any region front-loader NES (model NES-001) […]
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, […]
