15:1415:14, 7 May 2025 diff hist +503 N Emulation status Created page with "This page details the emulation status for various NVIDIA GPUs. == NV3 == Emulation is '''partially working'''. Most of the pipeline exists, the GPU is detected and drivers initialise on all known supported operating systems, and 2D partially works. However, serious issues understanding the screen to screen blit behaiour are preventing this part from working. Additionally, the DMA engine, required for 3D, is not yet emulated correctly. == NV4 == Very early research and..."

The NV3 version is fairly basic: it stores some manufacture-time configuration info, allows disabling and enabling interrupts, reading and writing interrupt status and enabling and disabling most other subsystems."

00:0300:03, 28 April 2025 diff hist +4,719 N PTIMER Created page with "'''PTIMER''' is a hardware subsystem that implements a 56-bit programmable interval timer with nanosecond-ish accuracy (it counts in nanoseconds, but cannot be nanosecond accurate due to the clock speed) and controllable speed. It is a foundational component of all Nvidia GPUs and, at least for late 1990s and early 2000s GPU designs, has not changed a huge amount (although some new registers have been added) since the NV1. It is required to, among other things, f..."

This causes garbage characters to appear inside of the Windows 98 Startup menu while trying to boot from CD-ROM. This bug is known to exist in very early S..."
