Um Jammer Lammy Recompiled 0.1.1 Playtest

This playtest update improves rhythm response and CD-XA audio fidelity.

• Reduces Um Jammer Lammy's host audio queue from the previous 180 ms default to a verified 60 ms target.
• Applies the title's configured audio target correctly during runtime startup.
• Replaces per-sector linear XA interpolation with the PlayStation reconstruction filter used by the Beetle reference, reducing harsh buzzing and preserving continuity between sectors.
• Retains the existing SDL3 controller support, WASD mapping, optional 16:9 mode, CRT presentation options, and clean-audio transition mod.

This is an owned-input setup kit. Supply a legally obtained Redump-style European disc (SCES-01753) and use Generate & rebuild. The archive contains OpenBIOS and source/tooling only; it does not contain game data, generated game code, saves, or captures. Windows binaries are unsigned.

Um Jammer Lammy Recompiled v0.1.0 Playtest

Windows x86-64 playtest build for Windows 10/11.

This is a source-only setup host. It does not contain Um Jammer Lammy game data, generated game code, a retail BIOS, saves, or captures.

Setup:

1. Extract the zip to a writable folder.
2. Run UmJammerLammy_Recompiled.exe.
3. Select your legally obtained Redump-style .cue + .bin dump of Um Jammer Lammy (Europe), serial SCES-01753.
4. Keep the bundled OpenBIOS selected.
5. Choose Generate & rebuild, then launch the rebuilt game.

Playtest features:

• SDL3 controller support, including Switch/Switch 2, PlayStation 4/5, and Xbox controllers.
• Digital-only controller mode and WASD keyboard mapping.
• Optional native 16:9 3D view; flat screens and movies remain 4:3.
• JVC and Sony Trinitron-inspired CRT presentation options.
• Clean Audio Transitions, enabled by default, which fades the frozen retry-screen reverb tail. Disable it under Audio mods for original PlayStation behavior.

Verification:

• Setup-host smoke test passed without launching SDL, BIOS, or game code.
• OpenBIOS Stage 1 route passed with zero static dispatch misses.
• SPU fidelity and Beetle reverb-oracle tests passed.
• Archive audit found no disc data, generated UJL game code, saves, memory cards, captures, or extracted boot executable.

The Windows binaries are currently unsigned. Windows may show a SmartScreen warning. macOS and Linux builds are not included because they require verification on native hosts.
