v0.1.0

The first release of Odin.

Odin (ᚨ) is a low-level emulator of the SEGA Hikaru arcade board. It runs the programs of the real chips wherever they are known, and draws with OpenGL or Vulkan. It is a hard fork of Valkyrie, by Stefano Teso.

Games

All six Hikaru games, two of them in two versions:

• Air Trix (airtrix, airtrixo)
• Brave Firefighters (braveff)
• Planet Harriers (pharrier)
• NASCAR Arcade (sgnascar, sgnascaro)
• Star Wars Racer Arcade (swracer)
• Cyber Troopers Virtual-On Force (von4)

They play with a keyboard, mice, gamepads, wheels with force feedback (NASCAR) or light guns (Brave Firefighters). Each game is a MAME ROM and needs the BIOS hikaru.zip and mie.zip too.

The PC needs a processor with SSE4.2 (2009 or later) and an OpenGL 4.3 graphics card (Vulkan can be chosen instead, in the menu).

First start

1. Put the ROMs and BIOS in a folder (e.g.: /roms/ and /bios/).
2. Start Odin, click File then Settings... or press escape key and go to Paths tab. From there, select the right folders.
3. Set up your controls in Input tab and your favorite settings in the next tabs.
4. The first time you play a game, calibrate its controls in its test menu (key 0, or Guide held with R3 on a gamepad).
5. If you have downloaded the Odin-Artwork.zip extract the content in your Odin folder, as long as it is in /Artwork.

INSTALL and OPTIONS tell the rest you need to know. Wiki pages will come later.
