README
This is a Daphne core.
Source Roots
------------
Original Source: http://www.daphne-emu.com/download/daphne-1.0-src.tar.bz2
Main Author: Matt Ownby
Other Authors: Mark Broadhead, Warren Ondras, Paul Blagay, Scott Duensing, Andrew Hepburn, Robert DiNapoli
Later Source: https://github.com/mirror/daphne-emu/tree/master/doc
- Not too much action on that repo.
- Quick glance shows most changes are in the Singe area which is not tested and, therefore, likely broken.
Quick Source History to Initial Commit
--------------------------------------
This core was based on the "Original Source" as above, which was released under GPL.
- Android was the first target system, and was the only supported system in the Initial Commit.
- Original source was ported from using Android incompatible SDL1 to SDL2.
- Then the source was prepared to be a standalone Android APK. A successful APK version was created but not released, as a Libretro core was thought to be the best mechanism for release.
- Finally, the code base coming a long way, we come to this core that you're looking at.
- Other platform code was left in place and even ported in a few places.
- Singe code was never tested or compiled in.
Game Compatibility at Initial Commit
------------------------------------
- Generally mimics original Daphne compatibility - it was never compatible with every Laser Disc game.
- "Test" type and Pioneer gear based cores were ignored.
- Key for "S" column:

Development Notes
-----------------
- Using Vulkan and Double Buffering can cut input latency by 16ms.
- Recommendations: Vulkan driver, Threaded Video: off, Vsync: on, Max Swapchain Images: 2, Input Poll Type: Early
Directory Setup
---------------
Initial path taken from RA during load, user points to a ROM zip file like lair.zip.
### Example:
1. Comes from RA: /storage/emulated/0/Roms/Daphne/roms/lair.zip
2. Then it's stripped down:
- Name: lair
- Extension: zip
- home_dir (where everything hangs off): /storage/emulated/0/Roms/Daphne/roms/..
3. Directories given above:
|Type |Directory |
|-----------|------------------------------------------------------------|
|pics: |[home_dir]/pics |
|ram: |[home_dir]/ram |
|sound: |[home_dir]/sound |
|framefile: |[home_dir]/framefile |
|CDROM: |[framefile_dir]/[first line in the framefile (IE lair.txt)] |
The only lair.txt that is considered is in framefile.
