What is the difference between .hr and .png?

Description: The HR file type is associated with the TRS-80, an early line of personal computers developed by Tandy Corporation in the late 1970s and early 1980s. Specifically, HR files contain high-resolution graphics data used by certain software applications or games on the TRS-80. These files were utilized to store and display detailed images or graphical elements beyond the standard graphical capabilities of the TRS-80's base hardware. Due to the limitations of the time, HR files were an innovative way to enhance visual experiences on the TRS-80 platform.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
