At least, <a href="http://www.machrone.net/mt/archives/2020/04/charts_graphs_a.html" rel="nofollow">I see audio geeks saying things like that</a>. I haven't exactly done a lot of trials but the cleanest waves I saw were from a GG and from wires soldered onto an SN76489 in an SC-3000.Maximhttp://www.smspower.org/maxim/noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-83581846609260137232009-06-13T08:47:06.592+09:302009-06-13T08:47:06.592+09:30Hi Maxim,

I took the S...Hi Maxim, <br />Thanks for your comment! <br /><br />I took the SMS audio from the chip directly, so do you think that a modded GG would yield a bassier sound? <br /><br />Also, I was wondering if there is a guide on how to replace the caps and which caps to buy? <br /><br /><br />Thanks heaps for all of your information as always, Maxim, much appreciated! :DSebastian Tomczakhttps://www.blogger.com/profile/12712567577323498804noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-60123733300193149552009-06-13T02:44:21.443+09:302009-06-13T02:44:21.443+09:30Most GGs need pretty much all their caps replacing...Most GGs need pretty much all their caps replacing - the screen gets unreadable and they eventually get finicky about powering on. I'd highly recommend it.<br /><br />In my experience, the GG headphone output is a lot less filtered than the SMS and does a much better job of maintaining the square wave under load (i.e. maintaining the DC offset) which helps make the sound more bassy.Maximhttp://www.smspower.org/maxim/noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-64854344914110967642009-06-11T21:29:22.843+09:302009-06-11T21:29:22.843+09:30Yes - the Game Gear has faulty capacitors as part ...Yes - the Game Gear has faulty capacitors as part of the headphone amp / audio amp circuits that need replacing (I think there are five caps that generally need replacing for the GG sound mod).Sebastian Tomczakhttps://www.blogger.com/profile/12712567577323498804noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-63689374606959700512009-06-11T21:22:00.003+09:302009-06-11T21:22:00.003+09:30interesting comparison! the GG's output, besid...interesting comparison! the GG's output, besides being quieter, sounds like a low bitrate mp3. any idea why that is? maybe you'll have to "prosound" your GG ;)Norockhttp://www.8bitdaily.comnoreply@blogger.com
