PSFlyCast v1.1.0-rc1

PSFlyCast v1.1.0-rc1

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.

PSFlyCast is a passion project, not a piracy project.

It exists so you can play the games you own on the console you own.

• Piracy is not condoned.
• No games, BIOS files, console firmware or decryption keys are included, and they never will be.
• Use only legally obtained backups of games you own, made yourself from your own discs.
• Use only BIOS files dumped from hardware you own.
• Requests for, or links to, games, BIOS files, firmware or keys are not welcome in this project's issues or discussions.

This is a release candidate: v1.1.0 as it will be released unless the candidate shows a fault. v1.0.2 offers it under Check for updates like any release; choose Skip this version there to wait for v1.1.0 itself.

Changes since v1.0.2

Added

• RetroAchievements. Settings > Achievements turns it on and signs in to your account on retroachievements.org with the console's keyboard; the password is sent to the site and not kept. An achievement earned shows over the game as it happens, and the quick menu lists the game's achievements. Softcore only: save states, cheats, rewind and fast forward stay as they are, and hardcore mode is not offered.
• Rewind (Settings > System, off by default, experimental). While it is on, the last three minutes of play are kept in memory, a moment every five seconds, and the quick menu's Rewind goes back to any of them. The memory cards go back with the game.
• A memory card manager (Settings > System > Memory cards, with no game loaded). It lists every card and its saves with their icons, copies a save to another card, deletes it, writes it to a file in the vmu folder and adds one from a file there (.vmi with .vms, or .dci). A card is kept as it was, as a .bak file beside it, before its first change.
• Favourites, hidden games and time played. A game's details have a new page, Manage: a favourite gets a star and a place on the Favourites shelf; a hidden game leaves every list (Settings > Library > Show hidden games brings them back, dimmed); and the page says how long the game was played and when last.
• Change cover, on the same page: the box art, the title screen or a moment of play from the covers' collection, the cover PSFlyCast finds by itself, or a picture of your own. Your own picture is never deleted.
• Fast forward in the quick menu, and as a control its Controls page can put on a button.
• Scanlines and CRT, two more choices of Settings > Video > Upscaling: the picture with a TV tube's lines, or with its lines, colour stripes, glow and darker corners.
• A software renderer (Settings > Video, or for one game; experimental): the processor draws each pixel with a software model of the Dreamcast's graphics chip, at 480p, for a game the graphics processor draws wrong. It is slower.
• Memory card screen (the memory card's little screen in a corner of the picture) and Stretch to fill in Settings > Video.

Fixed

• With USB drives on, the picture stayed at 60 Hz on a 120 Hz display. Outside its sandbox the driver could not find the title's own settings file, so it never asked for 119.88 Hz. PSFlyCast now tells it where the file is.
• The quick menu came back on the page it was left on. Closed with the touch pad from one of its pages (Cheats, Game options, Controls), it opened on that page again, with what the page had shown before. It now opens on its list every time, and a game option changed on the page is saved when the menu is closed that way too.
• Netplay of a Dreamcast game ended in "Peer verification failed". So did netplay of a game from a CDI, GDI or CUE image. The checksum the two players compare was taken of a memory address instead of the file, so it never matched. It is now the file's. Both players need the fix: against a copy of Flycast without it, on a PC for one, the check still fails.
• A game could go back to the BIOS in the middle of play because a status bit of the Dreamcast's processor that the game had set was never cleared, as it is on the console.
• A CHD image with over-long text in its track list could write past the memory set aside for it. The text is now cut to fit.
• The pointer jumped when a game changed between the two ways a mouse reports its movement.
• A trigger that reports as a button was not recognised when a control was given a button in the quick menu's Controls page.
• Damaged or crafted files and packets are checked before they are used: a disc's directory, a compressed save state, a name server's answer, an arcade game's file list, and the other player's input in netplay.
• From Flycast itself, in the 16 commits this version adds: a hazard in the per-pixel transparency renderer between one frame's render passes and the next, a save state with wrong lengths in it is refused instead of read, and packets from the other player in netplay and from DCNet are checked before they are used.

Changed

• The emulator is Flycast's dev branch at 4dca1988d; v1.0.2 had f83fda706. Save states and memory cards made with v1.0.2 are read as before.
• PSFlyCast is now built on the stack of PS5_VulkanTemplate: a newer RADV, a newer payload SDK, and a link step that refuses a build which calls a function the console does not have.
• The library that reads network shares, libsmb2, is its newest revision, with corrections to how it chains requests and to its text and encryption code.
• The updater knows release candidates. From this version on, a release is offered releases only; a candidate is offered the next candidate and then the release.
• Every web request PSFlyCast makes says what it comes from: PSFlyCast/1.1.0 (PlayStation 5) Flycast/<its version>.
• flycast-boot.log has lines starting storage:, saying which folders the title can write to. They are for a later version, which may keep your files outside the title's folder. Nothing is moved yet.
• The README and these notes open with the warning above.

Nothing was removed, and your settings, saves and games are kept when this version is installed over v1.0.2.

Tested for this release

I ran build 42 of v1.1.0 on my PS5. This candidate is build 44: build 42 with the fixes listed above from the netplay one down to the checks of files and packets, the updater's candidates, the newer payload SDK and libsmb2, and without a Screenshot row that build 42 had in its quick menu (the console's Create button takes screenshots). Build 44 itself has not been run on a console.

Confirmed on my console, on build 42:

• PSFlyCast as built on the new stack starts, shows its library and runs games as v1.0.2 did, with the saves, states and settings v1.0.2 left;
• the memory card manager;
• favourites, hidden games and time played;
• Change cover;
• the Scanlines and CRT filters;
• the software renderer;
• a USB keyboard and mouse as the Dreamcast's;
• the left stick as the joystick in arcade games.

Not confirmed on a console:

• achievements: signing in, an achievement earned in a game, the quick menu's list;
• rewind;
• fast forward;
• the memory card's screen and Stretch to fill;
• 119.88 Hz output with USB drives on;
• everything this candidate adds to build 42, netplay between two fixed copies among it;
• this version installed from v1.0.2's Check for updates, and Restart PSFlyCast now after it;
• from earlier versions: the Dreamcast's language taken from the console's; variable refresh rate; a second, third and fourth player; the games' own online modes; per-pixel transparency above 4x internal resolution; USB drives.

On the build machine: every new screen rendered from the real code; the memory card code on card images made for the purpose; rewind's store of snapshots and the software renderer under the compiler's thread and memory checkers, with made-up frames and states; the picture filters' shader compiled with the title's own shader compiler; the updater's ranking of candidates and releases; and the link's check, which stopped a build of this version that called a function the console does not have.

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

Known issues

• With USB drives on, PSFlyCast runs outside its sandbox, where the console can refuse it HTTPS: the update check, cover downloads and achievements may fail. Turn USB drives off and start PSFlyCast again for those.
• Rewind takes a snapshot of the whole machine every five seconds of play, which can show as a short hitch. It is off in netplay, in a game's own online mode and between linked arcade boards. What a game saved to its memory card after the moment gone back to is undone with it.
• The software renderer draws at 480p whatever the internal resolution is, without widescreen, and not for NAOMI 2 games or in netplay, where the graphics processor draws as before.
• Fast forward is held to the display: about twice a 60 fps game's speed with 120 Hz output, and no faster than normal at 60 Hz, where it only turns the sound off.
• Achievements need the console online when PSFlyCast starts; a saved sign-in that could not be used is shown as not signed in, and signing in again mends it. Should the console not open its password keyboard, the plain one opens and a notice says that the password shows as it is typed.
• While an update is downloading, other web requests (covers, achievements) wait for it.
• Restart PSFlyCast now, after an update, may only close PSFlyCast; open it again from the home screen. The new version is in place either way.
• With touch-pad aiming, a click of the touch pad still opens the quick menu: touch it lightly.
• A USB keyboard or mouse has to be connected, and listed in Settings > Controls > Controllers, when a game starts. They do not drive the menus.
• While Netplay is not Off, every game waits for another player when it starts. A Dreamcast game, or one from a CDI, GDI or CUE image, can only be played against another copy that has this version's fix.

Carried over from earlier versions, not checked again:

• With per-triangle transparency sorting some games show surfaces flickering in and out, depending on where you stand. Per-pixel draws them right: set it in that game's options, with 3x or 4x internal resolution and FSR 1.
• The highest internal resolutions are heavy, most of all with per-pixel transparency. If a game slows down, stays black or loses its HUD, go lower.
• The first time a game shows a new effect, or FSR 1 or a picture filter is first used, there is a short hitch while a shader is compiled.
• Too large an object draw distance can slow a game or break it; start with 2x.
• 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.

Install or update

1. From v1.0.2: Settings > About > Check for updates offers this candidate, downloads it and puts it in place. Your games, saves, settings and covers are not touched.
2. By hand, or from v1.0.1 and earlier: copy the complete PPSA99247 folder from the ZIP to /data/homebrew/PPSA99247/ on the console, over the folder that is there. Your games, saves, settings and covers are inside it, so do not delete it first.
3. Wait for ShadowMountPlus (or the launcher you use for titles in /data/homebrew/) to report the title ready, then start PSFlyCast.
4. 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.
5. Read LEGAL.txt, README.md and MANUAL.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.
