Into Aladdin's Caves 2 graphic bug

While playing the EMC set Into Aladdin's Caves 2, I came across a lot of question marks in level 1. Does this mean that some graphic is not supported? Could this be fixed?

As far as I can see, these game elements are really meant to be question marks -- here's a partial hex dump of the original Amiga level file:

Code: Select all

00000000: 8383 8383 8383 8383 8383 8383 8383 8383  ................
00000010: 8383 8383 8383 8383 8383 8383 8383 8383  ................
00000020: 8383 8383 8383 8383 8383 8383 8383 8383  ................
00000030: 8383 8383 8383 8383 8383 8383 8383 8383  ................
00000040: 8380 80af afd3 ccdd ccd3 afe3 efaf efaf  ................
00000050: efaf afef afef 10af efaf ef02 afef 10ef  ................
00000060: efaf ef10 afef 10af ef10 02ef 10ef 10ef  ................
00000070: ef10 efaf afef af10 afaf ef10 02af 9e83  ................
00000080: 83af afaf afef 02ef afef 02ef 1002 afef  ................
00000090: 1002 ef10 02ef efef af10 efef efef 10ef  ................
...
The "ef" bytes (decimal 239) are a valid, well-known element, which is indeed the question mark. (The many "83" bytes (decimal 131) at the beginning are the steel wall elements surrounding the level, while the several "af" bytes (decimal 175) are the internal code for dynamite, which is graphically displayed as a magic wand in this level set.)

So this is no bug or conversion error (which it indeed could have been, as in this case a question mark is used, too!), but intended by the level creator.

OK - well, then there's no problem at all :)
