Engines & Interpreters

Compiling the source

The repository will provide you a full set of all of the needed libraries. Take in mind that a lot of them are modified versions of the original ones so if you want to update them, take a look at this repository where you can find sourcecodes of every pre-builded library used in this repository. Also take in mind that libkhax includes also libSu sourcecode. Last but not least, please note that libjpeg.a file is a standard compilation of libjpeg-turbo.

Lua Player Plus 3DS supports different flags to enables some features:
-DUSE_MEMCHUNKHAX2 enables memchunkhax2 usage through svchax at startup for firmwares between 9.3 and 10.7.
-DCITRA3DS_COMPATIBLE removes romFs support causing Citra3DS emulator crash.
-DSKIP_ERROR_HANDLING disables error handling for faster code execution (this is used for Unsafe version).
-DFORCE_SD forces interpreter to load main script from SD instead of romFs filesystem.
-DFORCE_DSP forces interpreter to use dsp::DSP audio service even if csnd:SND is available.
