commit 4fbcde321da028f4d98ceb51839a53d6cf60917e
Author: QuzarDC <qu...@co...>

    vmulcd: Correct data type of vmu fb.
    
    There was, for some reason, a mix of the signed `char` and
    unsigned `uint8_t` as the types for the vmu fb. This caused
    possible unsigned conversion warning/errors when manipulating
    the data.
    
    Switched to `uint8_t` universally as the usage is for data we
    need to have specified by the width of it.
