 Hello,

 While trying to play the French version of ''Adibou 2 : Read/Count 6-7
 Yo'' ({{{adibou2readcount67}}}), I encountered an "unrecognized game
 variant" error.

 I dumped the MD5 hashes of my files and found the following:
 * {{{intro_ap.stk}}} : {{{0e91d0d693d5731353ad4738f4aa065c}}} (Size:
 {{{36540132}}})
 * '''{{{appli_03.vmd}}} : {{{d037d75824a033a5de4a45b9c02419ee}}} (Size:
 {{{58858}}})'''

 Looking at the current detection tables for the {{{gob}}} engine (in
 {{{tables_adibou2.h}}}), the listed entry is:
 {{{
 #!cpp
 AD_ENTRY2s("intro_ap.stk", "0e91d0d693d5731353ad4738f4aa065c", 36540132,
            "appli_03.vmd", "6bf95a48f366bdf8af3a198c7b723c77", 58858),
 }}}

 My {{{intro_ap.stk}}} matches the listed hash perfectly. However, my
 {{{appli_03.vmd}}} has '''exactly the same size''' ({{{58858}}} bytes) but
 a different hash ({{{d037d...}}}).

 '''The "Smoking Gun":'''
 As shown in the attached screenshot, the hash currently in the code
 ({{{6bf95a48f366bdf8af3a198c7b723c77}}}) appears to be a copy-paste
 placeholder. It is identical to:
 * {{{o1.pod}}} in the '''Hadesch''' engine (Size: {{{5 621 074}}})
 * {{{cdlogo.res}}} in the '''Teenagent''' engine (Size: {{{64 768}}})

 [[Image(image_cbea41.png)]]

 It is mathematically impossible for these three files of different sizes
 to share the same MD5. This confirms that the Adibou 2 entry needs to be
 updated with the correct hash ({{{d037d75824a033a5de4a45b9c02419ee}}}).

 Could you please update the detection table?

 Thanks for your amazing work!
