Hello guys, i'm having a big problem with the "R4 SDHC Upgrade Revolution". I've placed the firmware files into the micro sd (Kingston micro SD 2gb), but nothing happens, i've tried with the firmware's from the original website (http://r4i-sdhc.com). I also tried the firmware of R4DS, but it still shows no sign of life(by no sign of life i mean it goes directly to the normal nintendo ds menu ignoring the r4 cart i have inside). Has anyone met a problem like this? Or i'm a missing a step to let it load? Your attempts to help will be really appreciated.
Check the contacts in the DS, if they look alright then try the paper shim trick - a thin piece of card or folded paper to push the contacts of the Cart and DS together.
