tried on my M3 SD with No Trim, Normal. Works flawlessly and saves correctly.
using firmware 16, and the 3.12 M3 GM...
Ditto with CF, works perfectly not had a problem with saves so far, only tried normal and catch though properly.
Same with my M3 CFtrim rom, 4x, soft reset on M3 SD = no probs
To find out of you own a game with a Tetris-compatible save-type, check http://www.dualscene.net/viewpage.php?page_id=28
Select "Save Type" and enter "64" in the search field. I use Sonic Rush, currently.
Good luck!
it will probably take Supercard quite a while to patch this if ever (Puzzle Bobble still crashes)?Â
I play this on supercard SD, but I always get error 20107 (The game you are attempting to play on the Nintendo WFC has not been authorized.) when I want to play online
