I've had this problem for a while now, and I finally decided to see if it's fixable. I have an r4 clone, however, the only firmware that works on my card is the official 1.18 firmware for the original r4. It's called R4 Upgrade Revolution for DS. For reference, my card looks exactly like the one on the main page of http://www.r4iii.com/ and it support sdhc. And I have tried pretty much every other firmware, including the one from that site. Nothing works except the original. Now, to the problem. I wanted to use YSmenu on it for obvious reasons. I've tried many different ways of compiling the YSmenu, from auto generators to manual compilations. I can get the actual menu to run, either as default or booting as a YSmenu.nds file. Everything shows up correctly, including the cheats. However, when I try to run any game, it creates the sav/loads just fine, and then freezes with 2 white screens. This happens with all games I've tried, trimmed, clean, patched, etc. I've searched through a lot of forums and have noticed a few people with this problem, but no solutions yet. So I figured it's about time to make a thread and ask around here. Maybe someone has encountered this problem or knows of a solution. Thanks.
