Multiple revisions when prefer-revision-newer is enabled

[lostb1t]

I enabled --single and --prefer-revision-newer but I still get multiple versions of a certain game. Is it because it's unlicensed?

4 in 1 (Europe) (4B-001, Sachen-Commin) (Unl)
4 in 1 (Europe) (4B-002, Sachen) (Unl)
4 in 1 (Europe) (4B-004, Sachen-Commin) (Unl)
4 in 1 (Europe) (4B-005, Sachen-Commin) (Unl)
etc

Hi @sarendsen, No-Intro doesn't tend to provide parent/clone information for unlicensed games in their DATs. See the official igir docs for more information about parent/clone DATs.

The subsection of the Game Boy DAT in question from today/latest is:

we would expect to see <game name="..." cloneof="..."> if these games had parent/clone information. Example:

	<game name="A-mazing Tater (USA)">
		<description>A-mazing Tater (USA)</description>
		<release name="A-mazing Tater (USA)" region="USA"/>
		<rom name="A-mazing Tater (USA).gb" size="65536" crc="d229ac62" md5="53b746bff74c50cd3ebcf41161c66cf3" sha1="1e475cbd5fb7099df91155a103698e4e66da7a86"/>
	</game>
	<game name="Puzzle Boy II (Japan)" cloneof="A-mazing Tater (USA)">
		<description>Puzzle Boy II (Japan)</description>
		<release name="Puzzle Boy II (Japan)" region="JPN"/>
		<rom name="Puzzle Boy II (Japan).gb" size="65536" crc="e5463a1d" md5="1cdea2beb1f8f1f4a3fb0c939112267e" sha1="15e325be6272281d74448936fee5179448ae480e"/>
	</game>

That said, I have #431 logged as an enhancement I want to do that should help with this. No-Intro is good about parent/clone information in general, but other groups such as Redump seem to rarely include it.
