Exclamation-triangle-fill.svgThis OS is incompatible with the Turbo EverDrive V1


TEOS is an alternate operating system for the Turbo EverDrive V2.5 which offers various new features and bug fixes.

Features include:

  • Allows the TurboGrafx or PC Engine to use the Turbo EverDrive V2.X as a Super System Card. This avoids potentially damaging memory bus-fighting that occurs when booting the Super System Card software on the original Turbo EverDrive OS.
  • Adds the ability to "Backup RAM" contents to and from the Turbo EverDrive's SD card.
  • Adds the ability to copy the contents of a "Memory Base 128" addon to and from the Turbo EverDrive's SD card.
  • Adds the ability to use the Japanese "Tennokoe Bank" HuCARD utility.
  • Different looking main menu with a higher resolution font.
  • Various game-specific fixes listed on the project's GitHub.

Setup

  1. Format a 32GB or smaller micro SD card as FAT32.
  2. Download and extract the latest release's zip from the GitHub releases page.
  3. Copy all of the extracted contents to the root of the SD card. If you are updating TEOS, do not overwrite any files or you may lose saves.
    • At this point, TEOS will be listed in the Turbo EverDrive menu and can be run from there. However, if you'd like to completely replace the EverDrive OS with TEOS, rename TEOS.PCE to OS.PCE and move it into the TBED folder on your SD card.
    • If you are using a Turbo GT or Turbo Express or want to use a bigger font, use the TEOS-GT.PCE file instead, as it will use a larger font.
  4. Copy any desired games to the root of the SD card. Note that folders are supported, so you can place games in separate folders such as Games, Translations, and Homebrew.
  5. Safely eject the SD card and insert it into the Turbo EverDrive.
  6. On the Turbo EverDrive cartridge itself, look for a physical switch. Slide it to the "PCE" position if your system is a PC Engine or slide it to the "TG-16" position if it's a TurboGrafx-16.
  7. Insert the Turbo EverDrive into your console and turn it on. It should boot to a white screen followed by the TEOS menu.

Controls

  • I: Select highlighted item.
  • II: Go back to previous menu.
  • Run: Start previously selected game.
  • Select: Open Tennokoe backup utility. Press again to show help and system information page. Press again to return to main menu.
  • Reset: There is a physical button on the cartridge itself that will take you back to the EverDrive menu.

Booting CD Games

Normally, if you have a game in the HuCard slot, you can't boot a physical CD. Luckily, you have the option to place a BIOS file on your SD card and run it like you would any game to boot into the Super System Card BIOS to run a CD. It's recommended to either use TEOS as your operating system OR to apply the below "version 3.01" patch to the Super System Card 3.0 BIOS in order to safely avoid memory bus collisions.

Troubleshooting

Occasionally, you may run into the situation where upon resetting or a quick power cycle, you will be in a folder but unable to press II to return to the parent folder. If this happens, press Select three times, then you should be able to navigate as normal.

Support

If you run into any issues, please report them in the "Homebrew Development" section of the PC Engine Software Bible forum, rather than Krikzz's official forums.
