Subject: cdriso: parse .cd<X> files as .cue.
X-Git-Tag: r24l~622^2
X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2cc221eb6675f228e6ada72e3dc7d438babcfdc6;p=pcsx_rearmed.git

cdriso: parse .cd<X> files as .cue.

Enables the parsing of .cd<X> files as cuesheets.
Useful to 'hide' individual `.cue` files from the frontend
when using a multi-disc game configured in a playlist (`.m3u`) file.
