If you are not aware, be aware that new firmware for the fake R4 (1.19) has been released. This is NOT an update for the firmware for the real R4. The 1.18 real R4 firmware is the latest and unfortunately (based on Internet chatter) may be the last real update ever done for the R4. Good official R4 firmware: 1.18 http://r4ds.cn/download/r4.html Bad R4 clone firmware: 1.19 http://r4team.com/eng/downloads.htm
