Hi, brother, I want to ask why there is no test about vga cursors mode.Whether there is a problem with cursors logic？And Now how can I to verify the cursors mode.

Cursors were added a long time ago upon request. But they were never tested.

Please test them and if you find issues we’ll work on them.

Mr. Herveille, Thank you for your reply! Now I have some troubles about the cursors. First，Cursor Color Registers Address is different in Specifications（pp.7 and pp.17),and in design，i can't write DATA to cursor color register，maybe cause the “parameter [REG_ADR_HIBIT : 0] CCR0_ADR = 6'b01_0???” Second，in the design, the moude vga_pgen have a lot of undefined wire，such as “cursor_we”"dat_i""ssel1_q" "ssel1_wreq"， which connect the hw_cursor mode. Maybe i can connect the wire correct,but the result is wrong. Please help me, thanks a lot!!
