Updates:
1. Got most of the stuff to work on the 101.
-Priiloader works, and with Wiimote support too (there's a version that works with Motionplus remotes). Had to install it through WiiMod as it didn't work through HBC (complained about IOS36 not being patched even though IT WAS)
-USB Loader GX and CFG Loader work fine too. WiiFlow now starts, but trying a game will send me back to System Menu (like USBL GX did before) so gotta work on it too. d2x cIOS was the culprit as it wasn't installed at all.
-I downgraded to a DarkWii Blue themed 4.2E from the previous 4.3E
-I managed to replace the stock cables with a Gamestop 3-in-1 Component cable (has plugs for Wii, PS2 and PS3, and Xbox 360)
-Figured out why I couldn't get the SD Card to work as it should - I had the switch set in the LOCK position!

Didn't notice that until I googled the switch itself, LOL.
2. I still have the RVL-001 Wii, complete with its plugs and box.
-seller didn't care about it anymore, said he fixed the PS3 (I could care less in the end as I still have 5 working phats, among which one is a 4 USB model I took GREAT care of) so I don't really know what to do with it. I found an seller from Bucharest who has a lot of 16 broken Wiis, and among them I spotted 2x RVL-001s. Should I bite the bullet and buy one? He said most of them have mechanical issues (which sounds to me dud DVD-ROMs ahoy!) and I do know the dead one I have has a fully working drive, and the price he asks per Wii is relatively cheap ($10/Wii + ~$5 shipping). Is there an advantage of a 001 over the 101? As in, is it more flexible to modding over the 101?
