Oddities
There seem to be some odd results occurring, adding a note here to hopefully work out what's going on or work out a clearer solution.
Uses Traces Through {{Disambig}}?
The "uses" clause, which should return a list of pages that use a template seems to trace through {{Disambig}} pages and also include those pages. For example, this DPL should return pages with titles prefixed with "Ice" and using {{Problems/GC Widescreen Auto}}, a template only used on GameCube titles...
<dpl> uses=Template:Problems/GC Widescreen Auto titlematch=Ice% </dpl>
...Only the GameCube title page actually uses the queried template. Kolano (talk) 18:40, 28 November 2015 (CET)
Title Sorting Broken
Using ordermethod=title fails with a "API error: internal_api_error_DBQueryError" error breaking all page output.
<dpl> uses=Template:Problems/GC Widescreen Auto ordermethod=title titlematch=Ice% </dpl>
Use ordermethod=titlewithoutnamespace as a workaround.
Regex Filters
Filters using regex seem to be broken, generating a "API error: internal_api_error_DBQueryError" error breaking all page output.
<dpl> titleregexp=Moero.*$ </dpl>
Missing Results
This fails to pull in both redirects to Batman Vengeance (i.e. GBVE41 and GBVP41). Seems related to titles including a space in them, problematic for the checks in {{Navigation}} docmentation.
{{#dpl:
|linksto=Batman Vengeance
|redirects=only
}}
{{#dpl:
|linksto=Batman_Vengeance
|redirects=only
}}
Problem found, see here Template talk:Infobox VG#Is this still a thing? Lucario (talk) 20:16, 16 January 2018 (CET)
Category Limits
Category filters are limited to using 8 clauses, so nine in the example below will not be searched for.
{{#dpl:
|category=1|2|3|4|5|6|7|8|9
|redirects=only
}}
