CEmu

Warning This is where all the latest development happens! (build is from the master branch) Only use this if you want the bleeding edge (but still probably stable) or encounter any bugs as they might be squashed here.

Downloads

• Windows 10/11: Intel 64-bit / arm 64-bit
• macOS 12+: arm ; intel
• Linux (x64, glibc 2.29+): static ; dynamic

Builds are provided by our CI (GitHub Actions) directly.

Warning This stable release is rather old now, but CEmu is far from dead, we just don't make releases often - if you want to try the latest features, check out the nightly!

Here's the long-awaited release, filled with new somewhat-minor features, improvements, and bugfixes! Fun fact: did you know that we recently went over 211 commits? 🤓

Note that v1.3 should be last release before any new major one (planned to be v2.0 with source-level debugging, for C and TI-Basic code, no kidding!)

• TI-Bundle support has been fully reworked to be much simpler
• The autotester can now handle the new libs group format
