			<content type="html"><![CDATA[<p>Spot on with the math.</p><p>You should put a value of 8 in EAC for the offset correction value.</p><p>+2 is the offset of the disc itself (this is a very common value). We also have to account for the offset of the drive, so we add the two together to get the &quot;combined offset&quot;.</p><p>Let&#039;s pretend you had a drive with a negative offset, like -444. We wouldn&#039;t see garbage data in this drive, but if we figure out the combined offset with our disc offset (-444 + 2), we would know to use -442. Likewise, if you had a +667 drive, you could find large negative offsets, and figure out what to use in your SH-S223L by adding 6.</p><p>[It should be noted that combined negative offsets can give bad results in EAC, so in that case you will want to dump manually or use a tool like PerfectRip <a href="http://forum.redump.org/topic/4495/sega-saturn-megacd-dumping-guide/">(tutorial)</a>]</p>]]></content>

If you have a drive with a large positive offset (or a Plextor compatible with <a href="http://forum.redump.org/topic/2468/offset-detection-using-the-d8-read-command/">px_d8</a>) you can find out the disc&#039;s offset, then figure out the right combined offset by combining the disc and drive offset.</p><p>Having only two lines of garbage is okay. What&#039;s your drive&#039;s offset according to the <a href="http://www.accuraterip.com/driveoffsets.htm">Accuraterip</a> database?</p><p>According to the previous dumper, the offset for Lunar is -647. This means you can&#039;t manually detect it in a large number of drives. A large number of LG drives have +667, but if you&#039;re going to look into new drives, you might want to think about getting a Plextor (you can get them fairly cheap on eBay).</p>]]></content>
