M4: Detection conflict between M4/MADS engines for Orion Burger (FR)

Reported by: dwatteau Owned by: dwatteau
Priority: normal Component: Engine: M4
Version: Keywords: detection
Cc: Game: Orion Burger

Description

Current Git HEAD.

This is with the files from my own CD of the French release of Orion Burger (file listing/sums below).

In a --enable-plugins --default-dynamic --enable-engine=m4,mads build, I get the following output from ScummVM, when adding the game:

The game in 'orion-burger-fr' seems to be an unknown game variant.

Please report the following data to the ScummVM team at
https://bugs.scummvm.org/ along with the name of the game you tried to add and
its version, language, etc.:

Matched game IDs for the mads engine: nebular, phantom, dragonsphere, forest

  {"section1.hag", 0, "6db4bb8935c301dad067f38a7e97d7b9", 143233024},

   ^^^^
      note: false positive, DO NOT add it!

and I also observe the attached screenshot, where Orion Burger is suggested along with some MADS titles.

But my files for Orion Burger (French release) do match what's listed in the detection tables:

$ dd if=BURGER.HAS bs=5000 count=1 2>/dev/null | openssl dgst -md5 | awk '{print $NF}'
3887c30f0d2f93fed7549120748c07fd

$ grep -A 8 -B 5 3887c30f0d2f93fed7549120748c07fd ~/git/scummvm/engines/m4/detection_tables.h 
	},
	{
		{
			"burger",
			nullptr,
			AD_ENTRY1s("burger.has", "3887c30f0d2f93fed7549120748c07fd", 724755),
			Common::FR_FRA,
			Common::kPlatformDOS,
			ADGF_TESTING,
			GUIO3(GUIO_NOASPECT, GUIO_NOMUSIC, GUIO_NOSPEECH)
		},
		GType_Burger,
		kFeaturesCD
	},

The game does work if I force it to be recognized as Orion Burger (French). But since there's an exact match, the detection code for MADS shouldn't interfere with M4 (i.e. M4 has an exact match so it should always "win", in my opinion).

The conflict from MADS happens because Orion Burger (M4) has a SECTION1.HAG file, and MADS detection code checks for these files as well:

$ grep -i section ~/git/scummvm/engines/mads/detection_tables.h 
AD_ENTRY1s("section1.hag", "6f725eb38660de8af31ec7cdd628d615", 927222),

My bad, I did a search in the m4/mads categories but not in the Common one.
