Please answer the following question: Information:  - Game Jackal is a PC application developed by Antiguan - based company SlySoft that allows users to play PC game titles without the need for the game 's media to be in the CD - ROM or DVD - ROM drive . The program functions similar to a virtual drive ; however , instead of making use of large disc images , Game Jackal uses a proprietary format which takes up considerable less storage space by working to only capture data the game requires to run . Game Jackal is advertised to work with around 90 % of games on the market , including games such as Sid Meier 's Railroads ! , Neverwinter Nights 2 and Need For Speed Carbon . While the authors admit not every title is bound to work with Game Jackal , support is gradually improving and regular updates which combat various bugs and blacklisting , as well as expanded functionality in the building of its profiles . Game Jackal works by establishing a game profile which is used to store all of the game 's relevant data . To begin , an original copy of the game is needed to allow Game Jackal to successfully ' capture ' the game for use later . If a first attempt at capturing a profile does not succeed , it may be performed again : anything else Game Jackal picks up will simply be added to the profile .  - Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware and unlikely to need frequent updates) or application software in plug-in cartridges.  - A CD-ROM is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs which are not writable or erasable.  - Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan.  - An acronym is a word or name formed as an abbreviation from the initial components in a phrase or a word, usually individual letters (as in "NATO" or "laser") and sometimes syllables (as in "Benelux").  - CD-R (Compact Disc-Recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times.    Given the information above, choose from the list below the object entity that exhibits the relation 'instance of' with the subject 'game jackal'.
