Dev log #11

Hello.

This dev log brings news about a much larger addition to the Crosstalk ecosystem and outside of it than nearly everything before. My ISA, MISC, and the processor for it, DLU, which now supports my kernel, DANGLING, is now supported by my custom LLVM backend, which basically means that a large portion of UNIX-native C code can be compiled (assembled and linked, too) for MISC directly. I briefly mentioned this earlier, but now it's verified and can compile entire games, which can then run natively under DANGLING. POSIX libraries are shimmed to what used to be my utility library but it now also the standard library of DANGLING, LDG, or libdangling. I want to also support win32 eventually, but that's not currently a priority. However, the LLVM suite itself runs on Windows just fine and will ship with the game. Once Linux support comes to Crosstalk a few months after the Windows release, the LLVM suite will work the same way.

What is still missing is LLVM recognizing my custom binary format. It currently still reads my binaries as ELF32, though DANGLING itself reads my format directly and doesn't involve ELF.

The conclusion that there are some improvements to be made remains, so this post is just to show a bit more photos.Community4 Sep 2026Hardware Sniffers: The DLUWelcome to the next Hardware Sniffers post entry. Today, the topic is the DLU, which stands for the DANGLING Logic Unit , and it is the first CPU of the MISC architecture . The DLU consists of the following parts: · dangalu.sv: the DANGLING Arithmetic Logic Unit · dangdsu.sv: the DANGLING Sound Unit · dangddu.sv: the DANGLING Display Unit (80x25 text mode + a framebuffer mode, which some parts…Community3 Sep 2026Dropping old achievements that are no longer achievable at releasePrevious achievements are being removed so that the initial Early Access release state of the game contains only those that can be awarded at that time. They will return once EDA features return.
