While rumble packs can work mostly as intended (through HID PID) mempack emulation
This means the user mustĬonfigure this depending on the game.
The emulator needs to know what kind of pack to emulate (i.e. That are not met by the adapter-driver stack, etc) and restoring the original feel can require a lot of subjective tweaking. The exact axis value are often lost (calibration, dead-zone, assumptions on the exact axis range from the part of the emulator. This approach works with almost all controllers and adapters usable through SDL. So the emulator only needs to reformat the data to make it look like what a real controller would answer. Relatively fresh data is always available immediately (the SDL library returns it without delay) When the game being emulated requests a controller status update, an answer is built using the most recent. (The data is in fact stored in a buffer somewhere) 
This newly received data makes its way through a few software layers including the HID driver, the DirectX (DirectInput) or. 
The host PC polls the adapter over USB and receives the most recently read data. The adapter polls the controller and stores the answer containing button and axis status data in RAM. The normal event chain is more or less the following: (written with mupen64plus in mind, but also applies to project64) Here is a diagram outlining the main differences between the usual architecture (input-sdl) and this plugin. Please contact me if you get the chance to test. But the nice thing about this plugin is that I cannot test accessories I do not own yet. VRU (confirmed, requires special ports1_4 version of the plugin). Support for peripherals other than controllers. Wish to use and the game will take care of everything else. Potential support for any expansion accessory without any intervention nor device-specificįunctionality required on the part of the emulator, of the plugin or of the adapter (except forĪnd just like with a real N64 system, you simply need to insert the accessory you. The later immediately returns the controller's When the game must read the controller, the request is forwardedĭirectly to the controller by the adapter. The controller works, responds and feels exactly as it would in real life. Reads exactly the same axis values it would in a non-emulated setup. As the game talks to the controller directly, it So, what does this do for you? Many things! Here are the key advantages: To let the emulated game communicate with the controllers directly. Offered by my N64 to USB adapters (versions 3 and up) Project 64 plugins use the direct controller access feature Everything shown works! These mupen64plus and
