exult binary package in Ubuntu Lunar riscv64

 Exult is an open source engine for playing Ultima VII on a variety of
 modern operating systems and environments. The Black Gate (including
 Forge of Virtue) and Serpent Isle (plus Silver Seed) are both playable
 to the end. Some differences to the original games exist; see sections
 5.3/5.4 of the FAQ.
 .
 While it is possible to use the engine for other games, no such game has
 been written yet. Therefore, Exult is useless unless you own a copy of one
 of the Ultima VIIs.
