#13414: AGI engine no longer loads games missing from the detection tables
----------------------+-------------------------
Reporter:  Doomlazer  |      Owner:  (none)

 I'm unclear whether this intentional or a bug, but AGI games that aren't
 in the detection tables can't be launched in SVM version 2.2.x and above.

 For example, take a retail copy of SQ1 (DOS). It can be added and launched
 to any version of ScummVM without issue. If the game logic is modified in
 any way, as would happen for a fan translation, in WinAGI or AGI Studio
 the behavior changes.

 In ScummVM 2.0.0 everything works normally - it's identified as not being
 in the detection tables, but can still be added and launched.

 In ScummVM 2.1.x the game cannot be added, but if it's already there (i.e.
 added through 2.0.0) the game still launches successfully.

 In ScummVM 2.2.x and above the game cannot be added or launched.

 This is an uncommon edge case, but makes things more difficult for AGI
 translations since they must be tested in ScummVM 2.0.0 or lower until
 they are added to the detection tables.

 If this is intentional change, so be it, but since modified SCI games will
 still launch successfully in ScummVM 2.1.x and above I'm assuming it might
 be a bug with the AGI engine. Fixing it would remove some confusion for
 AGI translators who don't stumble on the fact that undetected AGI games
 can still be launched in 2.0.0.

 Since it's assumed AGI translations would eventually be added to the
 detection tables this is a low priority, but I thought I'd call it you
 your attention anyway. Thank you!
