I obsessively followed Stone Age Gamer back in 2011 and 2012 to get one of the first SD2SNESes (R.I.P. my first SD2SNES, 2012-2018). And I understand why they have to make this new major revision, but I really don't understand the anxiety over having to be the first to get one of these.
Like, you might get SA-1+MSU-1 support in the next year, but this is nothing compared to how big of an upgrade SD2SNES was over the PowerPak: better compatibility (full DSP series, Cx4, Satellaview, and the promise of future improvements), much faster loading, better menus, MSU-1, and use of SD cards instead of terrible CF cards (I bent a pin on one of my readers, and from that point on I was always afraid I'd do the same thing to the PowerPak itself). Oh, and maybe someday savestates might work better on the Pro, which is cool, I guess, if you cheat a lot?
