Contributions summary:Baltasar contributed primarily to the Z88DK project by adding features and improving the functionality of the Spectrum library. Their work included implementing controls for display attributes like brightness, flash, and inverse. They also added and modified functions to set cursor positions, print strings, and modify text output, while also refactoring some aspects. These changes improve the library's capabilities for developing software for the ZX Spectrum and other Z80-based platforms.
