This month we worked on ptrace, fixed some bugs, and are patiently waiting for new hardware.

This month we reworked signal handling, made optimizations, and fixed bugs!

This month we added AVX, AVX2, BMI1 and F16C support!

We have a few exciting news this month!

Happy new year! This month we addressed a few nasty bugs.

This month we got a lot of work done. Performance improvements, quality of life changes, and a bunch of testing.

This month felix86 was presented at the RISC-V Summit 2025 North America, and we added support for SSE 4.2 and made optimizations!

Welcome to another monthly blog post! This month we made optimizations and fixed a bunch of 32-bit games!

Welcome to the monthly felix86 blog post. Summer slowed us down a bit, but we are preparing some big changes for next month.

A major milestone for felix86 was reached this month!

Another month has passed, and felix86 development continues!

Welcome to another felix86 blog post. This month we got Unity and 32-bit games working and made many performance improvements!

A lot of progress was made during the month of April!

felix86 is a new x86-64 userspace emulator for RISC-V. It is aimed at achieving good performance in games, and as of now is in relatively early development. A few games are already fully working. As this is the first post, we are going to go through a brief introduction.
