This release introduces support for importing and managing external ROMs (for desktop mode only), providing greater flexibility for developers working with existing game assets. There are two new sprite properties available BANK_PROP and OBJPAL_PROP which enhanced coding flexibility for CGB sprites. Now emotes support 8x8px-per-tile based sprites. Fixed some known bugs, improved usability and compatibility. Added new tutorials chapters and content.
