Version history for NESTang - an NES emulator for Tang Primer 20K

v0.8rc, 10/31/2023 - The Tang Primer 25k release

  • This releases supports the new Tang Primer 25k, along with Tang Nano 20k.
  • For primer 25k, set up the memory module, hdmi pmod, dualshock2 pmod and microsd pmod as shown in here.
  • The primer 25k build supports the on-board USB-A port for P1, and the dualshock2 ports for P1 and P2.
  • For developers - the code base has been refactored to support both boards. Use gw_sh nano20k.tcl to build for nano 20k, and gw_sh primer25k.tcl to build for primer 25k.

v0.7, 9/18/2023 - FAT32 MicroSD

  • This release only supports Tang Nano 20K.
  • FAT32 MicroSD support. We have switched to FAT32 format for rom loading from MicroSD cards. Simply format your card in FAT32 and place all roms in the root directory.

v0.6, 8/20/2023 - USB gamepads

  • This release only supports Tang Nano 20K.
  • USB gamepad support. In addition to playstation 2 controllers, now low-speed USB gamepads can be connected to the board. USB connectors and a bit circuitry is needed. See usb_gamepad.md

v0.5, 6/4/2023 - The Tang Nano 20k release

  • This release only supports the new Tang Nano 20K board.
  • Direct controller support. Playstation 2 controllers (wired or wireless) can be directly connected to the board through a Sipeed adapter.
  • SD card support. Now games can be loaded through a MicroSD card. Use tools/nes2img.py to generate the SD card image. A simple menu system allows easy navigation. Press S1 button on the board to return to menu.
  • This is the first NESTang version that can operate standalone (without a PC). It is much easier to use. At the same time, game loading and controlling through the PC loader is still supported.
  • Other changes:
    1. Fixed a bug where there's no sound on some TVs.
    2. PS2 controller supports auto-fire buttons (square and triangle buttons)

v0.4, 10/22/2022 - Linux loader

  • New Linux loader for loading ROMs and connect gamepads. Tested on MangoPi MQ-Quad. Should also work on other ARM SBC boards.
