Here is my second proposal for the authors of GIME FPGA\/CPLD devices: [https:\/\/tlindner.macmess.org\/?p=1103<\/a>]<\/p>\n

As a reminder the first one was: [https:\/\/tlindner.macmess.org\/?p=977<\/a>]<\/p>\n

This proposes adding a single hardware graphic cursor avaiable in both text and graphics modes. An emulated example is avaiable in this Mame feature branch in my fork: https:\/\/github.com\/tlindner\/mame\/tree\/ots<\/a><\/p>\n

Here is an example program in BASIC to demo the feature:<\/p>\n
