Version 3.0 (Alpha)

Version 3.0 introduces a brand new build system which registers PortCE as a CMake package and also adds support for targeting emscripten.

• PortCE is registered as a CMake package
• PortCE can now target emscripten

New Features

• PortCE CMake package
• PortCE emscripten support
• Implemented some ti_real operations
• <ti/sprintf.h> functions like boot_sprintf

Other things have been added to the internal PortCE code if you want to modify things yourself:

• ti84cpeg.inc equates are available via the internal ti84pceg.hpp file
• Extra internal keybind presets are available.
• Custom memory interface via the internal PortCE_memory.hpp header

Migration Notes

PortCE no longer needs to be a submodule of your project (you can take a look at https://github.com/Sightem/libtexce for setting up PortCE as a submodule). You can look at PortCE/examples/hello_world to see how a PortCE project should be setup. You can copy the updated CMakeLists.txt template into your own project.

• ti_clock/ti_random et al have been replaced by ce_clock/ce_random
• typedefs such as ti_unsigned_int and ez80_unsigned_long_long now use <atomic.h> spellings (ti_uint and ez80_ullong)
• PortCE requires support for C17/C++20 along with _BitInt to build, so we recommend using Clang 18 or later.

Version 2.2

This version is mostly compatible with the guide from prime17569 https://www.cemetech.net/forum/viewtopic.php?t=20095

Version 2.0 brings a few things including:

• fontlibc
• zx0 and zx7 decompression routines (based off the eZ80 assembly implementations)
• better emulation of TiOS
• fixed behavior of RAM_ADDRESS(0) and etc
• some fixes to keyboard inputs
• Slightly different folder structure

Version 2.1:

• Mostly fixes to graphx/graphy
• Added PortCE_get_appvar_path. This allows one to do fopen(PortCE_get_appvar_path("MYAPPVAR"), "r") (although you may need to manually skip some header bytes to read the appvar).

Version 2.2:

• Implemented fontlib_GetFontByIndex and fontlib_GetFontByStyle by @Sightem
• Fixed issues in older C/C++ standards

Lots of files were switched from C to C++ to make things easier to maintain. GraphX and GraphY may have some new bugs introduced as a result, so please let me know of any issues and feel free to make contributions.
