3The VX Gaming handheld is a budget-friendly retro gaming device that emulates classic NES titles. Here's an overview of its internal components and capabilities:
🔧 Internal Components
Mainboard: Features a minimalistic design with a single-sided PCB.
Processor: Utilizes a "NES-on-a-Chip" (NOAC) encapsulated in an epoxy blob, integrating CPU, PPU, and audio functionalities.
Storage: Equipped with a 128 Mbit NOR flash chip (e.g., S29GL128P90), storing the preloaded games.
Power Supply: Powered by a Nokia BL-5C compatible battery, known for its widespread availability.
Hackaday
Display: The screen offers limited viewing angles and may cause visual discomfort during extended use.
Connectivity: Includes a micro USB port for charging and AV output for connecting to external displays.
The device boasts a collection of over 300 games, though many are repetitive or modified versions of original titles. Notable inclusions are:
Ms. Pac-Man
Dig Dug

🛠️ Modding Potential
While the hardware is simplistic, modifying the game library is challenging:
ROM Replacement: Technically feasible by interfacing with the NOR flash chip using specialized equipment like a FlashcatUSB programmer.
Limitations: The NOAC's compatibility is restricted to certain NES mappers, limiting the range of playable ROMs.
Community Insights: Enthusiasts have explored modding these devices, but the process is complex and not cost-effective for casual users.
