X

Yessir!!

Here's the GUI named "Nicomaki" running on the "Flaremina" kernel on "Yuezoemegumi" BIOS.

Flare and Mina. Yue, Zora, and Megumi. Nico and Maki!

XD

GUI is named after a Love Live ship lol

The Emmamiura OS, operating on the 16-bit Mindset-X computer, functions as a unified OS by integrating two distinct operating systems. The GUI and API, referred to as "Nicomaki," constitute the upper and middle layers, seamlessly running on the "Flaremina" kernel. Furthermore, the "Yuezoemegumi" firmware operates as an independent operating system, possessing its own kernel, userland, and server components.

ATmega328 is used for miscellaneous activities.

That was amazing

Other parts?

It includes an infrared sensor for use of almost all remote controls.

Viktor LS-2 can be jumpered to 0.79, 1, 2, 4, 8, 16 or 28 Mhz via NMI (which offers a lot other things too)

there’s a little window on the front enclose showing off Jenny from RGBDuino, used to synchronise the two boards.

The VRAMs of Gameduino, eVERA and Audreyhanamaru can be expanded up to 12.55MB, 7.25MB and 8.75MB.

Main RAM can be expanded to 2GB, only with expansion boards.

It has a modified, a bit more extended version of Texas Instruments TP0456 calculator chip inside for calculator app in the MX, offloading work from the CPUs.

VRAM: 3.75MB

It has seven graphical layers.

It is overlaid with Extended VERA and both synchronize with Gameduino allowing it to used to change video settings mid-frame. This allows the MX to change video configuration, including resolution, between scanlines and to display different horizontal resolutions, different colour depths, and entirely different frame buffers on the same screen. The EMOS graphical user interface allows two or more programs to operate at different resolutions in different buffers from all 3 video chips, while all are visible on the screen simultaneously. It can also be used to manually or automatically change registers within the video display at a specific time during screen draw. It can take 2- or more colour bitmap and changes the colour(s) as the screen is drawn without the need of extra VRAM.
×It can also change colour registers mid-frame, creating the "raster bars" effect. The hardware can go further than this and change the background colour often enough to make a blocky graphics display without using any bitmap graphics at all. The tech allows "re-use" of sprites; after a sprite has been drawn at its programmed location, the video can then immediately move it to a new location and it will be drawn again, even on the same scanline. It can trigger an interrupt when the video beam reaches a precise location on the display. This is useful for synchronizing the CPU and other GPUs to the video beam. The hardware can also be used to program and operate the blitter. This allows blitter operation and control to proceed independently of, and concurrently with, the CPU or other GPUs. It also has the ability to decompress 60 JPEG pictures per second while playing digitally recorded audio, essentially a form of Motion JPEG, as well as dynamically change the background at a very fast rate.

Genlock support. The genlock also includes a colouriser. In the case of a monochrome video camera, this signal is then fed into a colouriser, a device that takes certain shades of grey and turns it into colour as well as transparency. Another advantage is that it gives the operator the ability to continuously add layers of graphics, emulating the Scanimate. This makes possible the creation of very complex graphics.

It has the ability to provide effects such as window, mosaic and fades over the rendered graphics, as well as ability to apply the affine transformations on one or more background planes: translation, scaling, rotation, stretching, warping, pseudo-perspective, curved surface, reflection, shearing, skewing, pixelation and distortion, and go as far as even "emulating" kaleidoscopic effects. This transforms the background layer into a two-dimensional horizontal texture-mapped plane that trades height for depth. Thus, an impression of three-dimensional graphics is achieved. It supports a 16-channel DMA. It handles bitmap conversions, fast sprite and blitter compression/decompression via LZSS method and directly loading the video and graphics data to VRAM at rapid speed, bypassing the CPU and a support for hardware FIFO buffer.

It supports stretching sprites (horizontally, vertically or diagonally, or any combination of those), colour inverter, sprite transparency and sprite translucency, plus working with non-byte aligned data, and converting between bit depths.

Buffers include FIFO buffer, framebuffer, screenbuffer, multiple buffering (double, triple or quad) and page flipping. It includes line-buffer, alpha blending (4 per-texel alpha blending modes) and a reversible pixel clock for a frame grabber (a video capture device). It has sprite-chaining (basically combining several smaller sprites into a larger one and be treated as one)

The custom chip also supports vector hardware, a la Vectrex (albeit with endless choices of colours), with the image is projected by an electron beam, drawing lines like a laser show. With a special CRT or other monitor, vector images can be overlayed with raster ones, with very few VRAM needed to accomplish.

And thanks to sprite indirection, a sprite's data can be changed incredibly fast just by changing a pointer rather than copying a whole memory region.

Audreyahanamaru also has a primitive PIP (picture-in-picture) support

The BIOS Splash Screen And Sound can be customised (the image and sound when you boot ir up and let's you know it's all good)
