Known Limitations

This page summarizes the known limitations, bugs, and incomplete features of Free Eggbert as of the current repository state. See also Development → Known Issues for the detailed technical TODO list.

Gameplay

• Many movement and physics behaviors in decblupi.cpp need verification against the original game
• Enemy AI in decmove.cpp is incomplete; some enemies may not behave correctly
• Block/crate interaction logic in decblock.cpp has known issues
• The level editor (decdesign.cpp) has missing features
• Save/load (decio.cpp) may have version compatibility gaps

Rendering

• Double CPixmap::Create() call — may cause initialization failures with real DirectDraw
• Parameter swap — bTrueColorBack / bTrueColorDecor are swapped in the CPixmap::Create() signature
• Unsafe delete this in CacheAll(FALSE) code path — undefined behavior
• Suspicious rectangle initialization in CacheAll(TRUE)

Network / Multiplayer

• CNetwork::Receive() may not correctly copy received data into the caller buffer
• DirectPlay session lifecycle phases are incomplete

Audio

• README mentions BASS/BASSMIDI but default is DirectSound/MCI (_BASS=FALSE)
• Audio backend documentation may be outdated

Platform

• macOS support needs verification
• Web (Emscripten) build has limited testing; main loop adaptation may be incomplete
• Android build is functional but not fully polished
• Native DirectX 3 path may fail due to decompilation artifacts that FreeDirect tolerates

Build System

• target_include_directories for SPEEDY_BLUPI_WINDOWS uses PUBLIC where PRIVATE would be correct
• Whether /permissive- is appropriate for MSVC with decompiled code needs verification
• SDL runtime copying on Windows needs DLL target verification

Missing Documentation

• No Doxygen documentation on headers or source files
• .blp binary file format is not fully specified
• Visual region themes for each decor000–031.blp are not documented
