RGBDS (Rednex Game Boy Development System) is an assembler/linker package for the Game Boy and Game Boy Color. It consists of:

• rgbasm (assembler)

• rgblink (linker)

• rgbfix (checksum/header fixer)

• rgbgfx (PNG-to-Game Boy graphics converter)

NASM, the Netwide Assembler, is an 80x86 and x86-64 assembler designed for portability and modularity. It supports a range of object file formats, including Linux and *BSD a.out, ELF, COFF, Mach-O, Microsoft 16-bit OBJ, Windows32 and Windows64. It will also output plain binary files. Its syntax is designed to be simple and easy to understand, similar to Intel's but less complex. It supports all currently known x86 architectural extensions, and has strong support for macros.

FASM is an assembler that supports x86 and IA-64 Intel architectures. It does multiple passes to optimize machine code. It has macro abilities and focuses on operating system portability.

ASM6f is a fork of ASM6, primarily targeted at NES/Famicom development.

• Support for some illegal/undocumented opcodes

• FCEUX-compatible .nl output files

• Output of Lua-compatible symbol files

• New IGNORENL and ENDINL directives

• Support for iNES original and 2.0 header insertion

• Output of .cdl files, for use with FCEUX/Mesen

• Output of Mesen-compatible symbol files (both old and new formats)

• Generic +/- labels do not break @local scope

• Support for a: prefix to force absolute addressing for zero-page addresses.

armips is an assembler with full support for the MIPS R3000, MIPS R4000, Allegrex and RSP instruction sets, partial support for the EmotionEngine instruction set, as well as complete support for the ARM7 and ARM9 instruction sets, both THUMB and ARM mode.

Yasm is a complete rewrite of the NASM assembler.

Yasm currently supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes, outputs binary, ELF32, ELF64, 32 and 64-bit Mach-O, RDOFF2, COFF, Win32, and Win64 object formats, and generates source debugging information in STABS, DWARF 2, and CodeView 8 formats.

Blinkenlights is a command-line debugger that focuses on visualizing how software changes memory. It can emulate statically-linked i8086 and x86_64-pc-linux-gnu programs.

Cpu_features is a cross-platform C library to retrieve CPU features (such as available instructions) at runtime, and supports these CPU architectures

• x86-64

• AArch64

• ARM

• MIPS

• POWER

• RISC-V

• LoongArch

• S390x

xa is a high-speed, two-pass portable cross-assembler. It understands mnemonics and generates code for NMOS 6502s (such as 6502A, 6504, 6507, 6510, 7501, 8500, 8501, 8502 ...), CMOS 6502s (65C02 and Rockwell R65C02) and the 65816.

ACME is a 6502, 6510, 65c02 and 65816 cross assembler that supports global/local/anonymous labels, offset assembly, conditional assembly and looping assembly. It can include other source files as well as binaries while assembling. Calculations can be done in integer or float mode.

GNU Lightning is a library that generates assembly language code at run-time. Thus, it is useful in creating Just-In-Time compilers. It abstracts over the target CPU by exposing a standardized RISC instruction set to the clients.

The Advanced Scientific Data Format (ASDF) is a next-generation interchange format for scientific data. This package contains the Python implementation of the ASDF Standard.

Skyfield computes positions for the stars, planets, and satellites in orbit around the Earth.

Python Tools for HST ACS (Advanced Camera for Surveys) Data.

Orbital is a high level orbital mechanics package for Python.

This package includes an extension for the Python library asdf to add support for reading and writing chunked Zarr arrays, a file storage format for chunked, compressed, N-dimensional arrays based on an open-source specification.

Hubble Space Telescope image combination using the drizzle algorithm to combine astronomical images, to model image distortion, to remove cosmic rays, and generally to improve the fidelity of data in the final image.

PySM generates full-sky simulations of Galactic emissions in intensity and polarization relevant to Cosmic Microwave Background experiments. It is a large refactor of PySM 2 focused on reducing memory usage, improving performance and run in parallel with MPI.

Astral is a Python module that calculates times for various positions of the sun: dawn, sunrise, solar noon, sunset, dusk, solar elevation, solar azimuth, rahukaalam, and the phases of the moon.

GenetIC is a code to generate initial conditions for cosmological simulations, especially for zoom simulations of galaxies. It provides support for "genetic modifications" as described by e.g. Roth et al 2015, Rey & Pontzen 2018. It also supports 'splicing' as described by Cadiou et al 2021.
