Technical information
Sega Saturn Software Development Standards, SOA version 2.0 65
However, when a halfway play (disc 1 play only) ends at a highly
inappropriate location (when it might be mistaken with a fatal bug),
the game play should not be forced with the above message. In that
case, display a message to prompt clearing other applications game
data and display the amount of space required, and do not allow the
game to start. (Message: Appendix 1: <Backup Software Production
Standards>)
5. Recommended specs to link games
smoothly
So far, by creating specs that complied with standards, after ending
the disc 1 game and moving to disc 2, the following screens were
processed:
1) <Disc 1> <Disc switching message>
2) Console boot ROM <Multiplayer screen>
3) <Disc 2> <License Sega logo screen>
4) <Disc 2> <Title screen>
5) <Disc 2> <Game data select screen>
During the story line, for the user, these screens are distractions to the
flow of the game. Therefore, we recommend the following specs to
minimize these procedures:
• After <disk 1> is finished playing, create <transition state data>
to <disc 2> within the save data.
• When the application confirms <transition state data> within the
backup RAM, read this data with the highest priority (ignoring
other game data).
• When switching discs through <transition state data>, at a
minimum, take the following steps:
(<normal data> game file on <disc 1>.)
(Rewrite <normal data> temporarily to <transition state data>.)
1) <Disc switching message> on <disc 1>.
2) Main console boot ROM <multiplayer screen>
3) <License Sega logo screen>
(<transition state data> recognition>)
4) Immediate return to the application (game play)
(Rewrite <Transition state data> to <Normal data> starting from
<disc 2>.)
