Hacking my r4 is freezing randomly

[sheepgod5000]

i was just wondering if you guys know what is up. i mean its not freezing at any specific time except when i close the ds sometimes (rarely) and it has happened a few times while playing new mario bros.

also this is the r4 i have (i think its the real deal) http://www.dselite.com/R4-DS-Revolution-p/203.htm

im also running the ysmenu on my ds

hmm... It looks like the real deal, but there are plenty of clones out there now so I can't be certain at all. Try reformatting your micro SD and use 1.18 firmware w/o ysmenu and play untrimmed roms. If that doesn't work, you either have a faulty card or a cheaply made clone.
