1.1.9
Summary
This release adds the long-awaited piano roll among other useful features and fixes various bugs.
As always, feel free to ask questions about anything in the Mupen64 Development Discord Server. Bug reports and commisioned features are greatly appreciated and help sustain the development.
Piano Roll
The piano roll is the latest major addition to Mupen64.
Its main functionality is viewing and modifying the inputs in a movie. In contrast to traditional frame-by-frame TASing, the piano roll opens up the possibility of modifying frames prior to the current one.
Ecosystem Updates
🟢 SM64 Lua Redux 3.0.0 - Adds SM64-specialized Piano Roll!
🟢 hacktarux-azimer-rsp-hle 0.3.0
🟢 mupen64plus-rsp-hle 1.0.0 - New port of the mupen64plus RSP plugin, offers better performance in some situations
Documentation
Mupen64 now has rudimentary user-facing documentation! 🥳

- View: Show more information during capture
- VCR: Change movie backup names (now use a period as the separator)

Breaking Changes
