Mupen64
|
Mupen64 is a Nintendo 64 emulator useful for its TASing capabilities.
There are many forks of Mupen64, the primary community-maintained one being mupen64-rr-lua, which is nearly universally used for TASing Super Mario 64
Mupen64plus
Mupen64plus (stylized as mupen64plus) is an emulator used for real-time gameplay.
It is generally preferred in this regard over Mupen64. Mupen64plus, as well as m64p-based frontends such as OpenEMU, are also allowed for Super Mario 64 speedrunning.
mupen64-rr-lua
mupen64-rr-lua is an emulator used for TASing and is most commonly used to record and play back TAS movies.
It is a fork of Mupen64-RR-lua which is actively maintained by the community. It introduces the lua scripting extension, QoL features, and security patches

Features
Lua
mupen64-rr-lua supports Lua scripting, which gives it much more power for testing and brute forcing[1]. It is used for TASing, as well as for testing and preparing.
Show Ram Start
copies the Ram Start address to the clipboard to configure an external RAM-watch like STROOP.
Emulate Float Crashes
mupen64-rr-lua supports crashing during certain float-to-short exceptions just like the Nintendo 64 console does. This is a useful alternative to console verification, but not as reliable, because there are still some unknown crashes.
Clock Speed Control
mupen64-rr-lua supports changing the emulated CPU's clock speed with a multiplier, allowing lagless emulation.
WiiVC Rounding
mupen64-rr-lua supports emulating the Wii VC Round-To-Zero oversight[2]. It has been used, among other things, by pannenkoek2012 to TAS the Bowser in the Fire Sea 0x A presses run[3].
