The later DSP-1A and DSP-1B serve the same purpose as the DSP-1. It provides fast support for the floating-point and trigonometric calculations needed by 3D math algorithms. It is used as a math coprocessor in games such as Super Mario Kart and Pilotwings that require more advanced Mode 7 scaling and rotation. The DSP-1 is the most varied and widely used of the Super NES DSPs, in more than 15 separate games. All of them are based on the NEC µPD77C25 CPU and clocked at 8 MHz. The DSP-1 version, including the later 1A die shrink and 1B bug fix revisions, was most often used the DSP-2, DSP-3, and DSP-4 were used in only one game each. The chip has four revisions, each physically identical but with different microcode.

This series of fixed-point digital signal processor chips provides fast vector-based calculations, bitmap conversions, 2D and 3D coordinate transformations, and other functions. CX4 wireframe test screenĪ Cx4 self-test screen can be accessed by holding the 'B' button on the second controller upon system start-up in both Mega Man X2 and X3. The name Cx4 stands for Capcom Consumer Custom Chip. It is based on the Hitachi HG51B169 DSP and clocked at 20Mhz. It maps and transforms wireframes in Capcom's second and third games of the Mega Man X series. The Cx4 chip is a math coprocessor used by Capcom and produced by Hitachi (now Renesas) to perform general trigonometric calculations for wireframe effects, sprite positioning, and rotation.
Variants of the Super FX chip sorted chronologically. The differences are in packaging, pinout, maximum supported ROM size, and internal clock speed. All versions of the Super FX chip are functionally compatible in terms of their instruction set. The final known revision is the GSU-2-SP1. The design was revised to the GSU-2, which is still 16-bit, but this version can support a ROM size greater than 8 Mbit. Both the MARIO CHIP 1 and the GSU-1 can support a maximum ROM size of 8 Mbits.

The GSU-1 however runs at the full 21.47 MHz. Both versions are clocked with a 21.47 MHz signal, but an internal clock speed divider halves it to 10.74 MHz on the MARIO CHIP 1. From 1994, some boards have an epoxy version, and later a first revision is labeled GSU-1. This chip has at least four revisions, first as a surface mounted chip labeled "MARIO CHIP 1" (Mathematical, Argonaut, Rotation & I/O), commonly called the Super FX, in the earliest Star Fox (1993) cartridges. Super Mario World 2: Yoshi's Island uses the Super FX 2 for sprite scaling, rotation, and stretching. It is typically programmed to act as a graphics accelerator chip that draws polygons and advanced 2D effects to a frame buffer in the RAM sitting adjacent to it. The Super FX chip is a 16-bit supplemental RISC CPU developed by Argonaut Software. Everybody's mileage will vary of course.Main article: Super FX Super FX renders 3D polygons in Star Fox. I disable Threaded Video and make sure the Audio Resampler is set to "lowest."īilinear filtering works well, as do a few shaders. I set input polling to "late" instead of "early." I also generally leave the audio buffer alone. It may be a placebo but it seems that helps a great deal. I am curious to see what a tethered controller over OTG does.Īnother area I think helps, (but I have no way of testing) is setting the aspect ratio to "Core Provided" and Integer Scaling that.

I am not 100% sure on this, but keeping it to 1 or 2 feels tighter than than 0, (It's default is 1.)Įven still, I have found despite Libretro's robust latency reduction tech (way tighter responsiveness than the stand-alone Snes9x emulator on the Google Play Store) I think Android and Bluetooth are more inherently laggy than Windows and Bluetooth. What I didn't realize at the time, but after scouring Libretro's forums, was this can have a similar effect to frame delays or late input polling. Not sure if it helps, but there's an option in the latency settings that is supposed to help multiple button inputs by delaying the emulator. I was doing 2 runaheads but the animation chopping off threw me off. I activate "auto-frame delay" so it can drop that if the FPS suffers and audio gets choppy. I keep a moderate amount of frame delays. (Getting 1 frame tighter is better than struggling to achieve perfect sync with CPU and GPU which I believe happens with some Android devices.) I usually run Hard GPU Sync to "0" on other devices, but after some experimenting, 1 for Snes9x works for me. I use a Samsung A32 5G with a Bluetooth X Box One controller.
Yeah I tried a few things from that video.
