v1.2.0 - Android Has Joined the Family! Quality-of-Life Improvements to the Joysticks + Expanded Switch Capabilities

The Binding of Isaac — Native Recomp v1.2.0

Android arrives, plus analog movement on every stick and touch controls on Switch.

📱 New: Android version

• Native APK for 64-bit ARM phones and tablets with Android 7.0 or newer (OpenGL ES 3.0).
• Touch controls: semi-transparent joysticks appear where you put your finger: left half to move, right half
  to shoot. Tap the bomb counter, the active item and the card/pill to use them, and use the pause button next
  to -LIFE- (or the back button/gesture).
• Bluetooth / USB controllers work as on PC and can be mixed with touch.
• Automatic resolution: renders at 720 lines and steps down to 600 / 540 / 480 if the device can't keep 60 fps
  (or set render_height yourself). Runs at the screen's refresh rate, 90 / 120 Hz included.
• Low-latency audio (AAudio) mixed at the device's own rate. The run is paused and saved when you leave the app.
• The game, settings, saves and logs live in the IsaacRecomp folder at the root of the internal storage.

🕹️ Analog movement (all platforms)

• With an analog stick (controller, Switch, touch joystick), Isaac's speed now follows how far you push it,
  like in Rebirth. The dead zone is followed by 40 % speed, rising to full speed at ¾ of the stick's travel.
• Top speed is never higher than the original. Keyboard and D-pad are unchanged.
• New isaac.ini option joystick_acceleration (on by default; 0 restores the original all-or-nothing movement).

🎮 Nintendo Switch

• The touch screen now works during play in handheld mode: the same joysticks, HUD taps and pause button
  next to -LIFE- as on Android (the button is hidden when docked). touch_controls = 0 turns them off.
• The left stick is now analog (see above).
• The Homebrew Menu now shows the author and version 1.2.0.

💻 PC

• Controllers in menus: menus and the pause screen can be used with the controller alone (A confirms, B goes
  back, D-pad / left stick choose). Start / Back pause.
• New isaac.ini option performance = 1: the performance overlay (F3) is on from startup.

🔊 Audio (all platforms)

• Sound is mixed directly at the output device's sample rate with cubic interpolation, instead of being resampled
  twice. Cleaner high frequencies.

Saves are compatible with v1.1.0 and can be copied between PC, Android and Switch. On PC and Switch, just replace
the program files; your isaac.ini keeps working, and new options take their default values.

v1.1.0 - Perfomance and Gameplay Fixes and Improvements

Bug-fix and performance update over v1.0.0. All versions of the recomp were affected.

Fixes

• Blood/creep puddles dealt "random" damage. The floor check was done at the wrong spot (1.5×–2.25× away from the player), so puddles far away could hurt you and the one under you sometimes didn't. Now it matches what you see.
• Slowdown in long sessions (and crashes on Switch after 20–30 min). Every sound left an invisible object behind; thousands piled up over time.
• Hitches after ~30 min of play. The game now produces ~60% less memory garbage, and cleaning it up can no longer make a game tick miss its deadline.
• Eternal Edition: the hard-mode mark no longer appears on the HUD when hard mode is off.
• The learned preload list no longer grows without limit, and preloading never fills more than ~60% of the texture atlas.
• Sound durations now use each sound's real sample rate.

Improvements

• Lower input latency: the controller/keyboard is read continuously while waiting for the display, so presses don't wait for the next frame (low_latency = 1, on by default).
• New experimental option interp_lead in isaac.ini (0–0.5) to draw the image slightly ahead. Visual only; the game logic is not affected.

Full Changelog: v1.0.1...v1.1.0

v1.0.1 - Fixed a Critical Bug and Improved Input Lag

Thank you very much for early feedback! The changes will be reflected in the source code shortly. Quick summary:

• Fixed a critical bug related to the game's sound system, which was accumulating objects and keeping them in memory, causing crashes during long sessions.
• Eternal edition: the pentagram symbol on the HUD now only appears in “HARD MODE.”
• Input lag has been slightly improved.

v1.0.0 - First Public Release

First official build of the project! I'm really happy with the final result. Give it a try and let me know what you think. Remember that you need the official game for this to work
