Subject: [PATCH] SH/Dreamcast - improve detection of attached peripherals
Date: Mon, 11 Feb 2008 00:25:02 +0000	[thread overview]
Message-ID: <1202689502.6237.23.camel@localhost.localdomain> (raw)

Improve device detection for maple through longer delay

Experience suggests that a much longer delay in setting up the Maple bus
on the Dreamcast leads to better hardware detection.
