Revision as of 19:42, 28 October 2016

The Everdrive N8 is a flash cartridge made by Krikzz. It uses an FPGA to emulate a wide variety of mappers, allowing the user to store a large collection of ROMs on a single SD card and run them on an NES or Famicom.

In addition to NES ROMs, the Everdrive N8 is able to play FDS disk images.

Famicom expansion audio is supported, and on the NES version is output on the EXP 6 expansion pin on the cartridge connector as used by the PowerPak. A simple modification to the NES allows the expansion audio to be mixed with its output.

Mapper compatibilty

The OS update v14 in October, 2016 supports the following mappers:

240 241 242 243 --- 245 246 --- --- --- --- --- --- --- --- ---

Known problems:

  • Mapper 5 (MMC5) does not support expansion audio.
  • Mapper 69 (FME-7) does not support expansion audio.
  • Mapper 85 (VRC7) does not support expansion audio.

Software development limitations

Aside from mapper incompatibility, there are minor differences between running NES programs on the Everdrive versus a traditional single-game cartridge.

  • The Everdrive does not accurately simulate power-on state. Because power-on always boots the Everdrive menu, RAM and various registers will be initialized to a consistent state before any NES ROM is chosen to run. (Reset state, however, is not affected by this problem.)
  • Open bus behavior may be different in several memory regions that are used by the Everdrive, but would not be connected on a regular cartridge. (forum post)
  • The Everdrive is incompatible with an NES that has the CopyNES modification installed, due to a bus conflict with its boot code.
