PSFlyCast v1.0.0

Flycast, the Dreamcast, NAOMI and Atomiswave emulator, as a native app for a
jailbroken PS5, with a controller-only interface and the emulator's Vulkan
renderer drawing through RADV.

Important

Piracy is not condoned. This release contains no games, no BIOS files, no
console firmware and no decryption keys, and none will ever be provided or
linked to. Use only legally obtained backups of games you own, made yourself
from your own discs, and BIOS files dumped from hardware you own. Please
don't ask for, or post links to, games, BIOS files, firmware or keys in issues
or discussions: they will be removed.

Highlights

This is the first release.

• Its own title on the home screen. No other emulator front end is needed:
  copy one folder to the console and start it.
• A library made for a controller. Shelves, a grid or a list; covers and
  descriptions downloaded by file name; jump by letter with L2 / R2; game
  details on Triangle; five skins, seven backgrounds and a start-up animation.
• Games from three places. The internal folder, USB drives, and SMB network
  shares, read into memory before they start or streamed.
• Options for one game. Every setting can be set for a single game, before
  it starts or from the quick menu while it runs. The quick menu also has save
  states with a picture of each, disc changes, cheats, control remapping, a CPU
  clock setting and Restart game.
• Games on several discs are one entry, and the next disc is offered first
  when a game asks for it.
• 4K output, at 119.88 Hz where the display takes it.

Tested for this release

I ran the build in this ZIP on my PS5 before releasing it: it starts, shows its
start-up animation and its library, and plays Dreamcast games.

Over the builds that led to it I also ran, on the same console: games from the
internal folder and from an SMB share, with a real BIOS; cover downloads; the
quick menu and the per-game options; a game on several discs, grouped in the
library and swapped from the quick menu.

I took no frame-rate or audio measurements, so this release makes no speed
claim.

Not run on a console, or not confirmed one by one: USB drives

Known issues

• Per-pixel transparency at 6x internal resolution drew no frames in one test.
  Use per-strip transparency, or a lower resolution, if a game stays black.
• The first time a game shows a new effect there is a short hitch while its
  shader is compiled. The title remembers what each game used and prepares it
  at the next start, so this is felt most the first time a game is played.
• No game patches (60 FPS, widescreen) are included: the community chart they
  come from states no licence. The README says how to make your own list. The
  About screen still credits the chart.
• Cover downloads may stop working while USB drives are on.
• A network share is named by its IP address; a server name is not looked up.

Install or update

1. Copy the complete PPSA99247 folder from the ZIP to
   /data/homebrew/PPSA99247/ on the console. When updating, copy it over
   the folder that is there: your games, saves, settings and covers are inside
   it, so do not delete it first.
2. Wait for ShadowMountPlus (or the launcher you use for titles in
   /data/homebrew/) to report the title ready, then start PSFlyCast.
3. Put your own legally obtained backups in games/, and BIOS files dumped
   from your own console in bios/ (optional for Dreamcast games). None are
   included, and none ever will be.
4. Read LEGAL.txt and README.md in the folder.

Reporting problems

Send flycast-boot.log and flycast-boot.1.log from the title's folder, and
say which build it is (Settings > About, or the log's first lines). Copy the
logs before starting the title again. Never attach game files, BIOS files,
firmware or keys.
