I recently bought a Datel SDML for my NTSC DOL-101. I also bought some of those Ritek Ridata Mini-DVDs with the purple colored data side, I heard that these were supposed to be very reliable. I put GCoS 1.5 and the 1.x Beta, as well as Swiss. I have a Pioneer external burner (I have heard that Pioneer is a good brand of burner) and I use ImgBurn at 2x. I tried three games: Mario Sunshine, Smash Bros. Melee, and Starfox Assualt; SMS and SSBM were burned as .iso at 2x, and SFA was burned as an .iso at 1x. I've used my multimeter to adjust my laser at almost every spot ranging from 90 to 300 ohms. None of the games have worked, all come up with DREs and "an error has occured" at various spots depending on the booter, game, and POT adjustment. In the case of SFA; the game did not boot up at all. I think the closest I've gotten is mid way through the intro movie (with freezing and stutters, of course) on Mario Sunshine before crashing and getting to choose my character in Melee. I've read many guides on running GC backups, and I have no clue what I'm doing wrong and was wondering if the kind GameCube enthusiasts at GC-Forever could help. Thank you.
PS. The burned games run in Dolphin, so I figure it's not the burner, file, or discs. I'd much rather play them on the real deal rather than 9 FPS on Dolphin.
