Okay, so, got this "arcade_update_v2.3_1114.img" file from the Legends Flashback page on AtGames' site, and since the instructions included both "arcade_update.img" and "atari_update.img" directives, put in on a FAT32 4GB SD card (with about 122 MB available beforehand), but after the initial question, just keeps looping its update, "Error"ing when I try to interrupt or reboot it, and once got it to bring up an MS-DOS-lookin' menu. So, what's different between this file and the one in the OP that it would be giving me this hassle?
EDIT: Weeellll, after applying the update provided by OP, I find there's just nothing on my system, now. How...do I repair this? Other than to exchange it, maybe, unless I wanna damn some poor soul to an empty gift.
EDIT2: Also, the P1 joystick seems to go unresponsive if I idle about in the menus for too long (though maybe I'm just not recognizing where it's positioned). Shot an e-mail to AtGames, but...*sigh* we'll see.
