Like I've said, I'm searching for the firmware of a R4 clone: R4iSDHC Silver (http://www.r4isdhc.com/). Manufactured in 2012, it is no longer supported by its creators. It didn't even appears in the whole page. Some time ago, I lose all the available files in my SD cards and my HDD. The firmware was inside those drives. Like you've guessed, I lose them. ;( Now, that I'm searching a link to download it, I can only find this: http://web.archive.org/web/20121105230637/http://bbs.r4isdhc.com/forum.php?mod=viewthread&tid=10 If someone here is so humble to send me a link to download it, I would be VERY pleased. PD: I found a link to the firmware, but an early version of it. It means it supports few (really) few games. Cheers and have a nice day!
