Hello everybody, I am back again. I've just bought RK26 player with RKP platform for 79PLN which is about $28
MP4 Vedia C3 - Okazja!!! Polecam!!! (1702448231) - Aukcje internetowe Allegro
It has RK2608 + Wolfson chips, 2GB internal memory + MicroSD slot. It supports RKP games, FLV (320x240 FLV ver1), APE and FLAC formats

))
Though I have to wait for it until 24 of July when the seller comes back from his vacation.
It is used, it has built-in speaker (but it seems to be broken somehow - nonetheless if it's just unplugged cable or broker speaker, I will put there some better modern loud-and-clear mini speaker

)
I want to start programming in RKP platform again, I have very sentimental value for RK26 players - my very first player (TECLAST C260 clone) had already gone dead (screen doesn't work - it's probably just screen connectors), so I abandoned everything connected with RK26.
Later I bought RK27 player - the same as yours KNOB - it's great beside that audio issue (remember knob? do you still have yours?). For a long time I abandoned because the battery was really shitty (it didn't hold for even 10 minutes after 24hours of charging), but surprisingly, when I lately started to use it, the battery holds for about 6 hours of constant playback
So, I am just wondering, how much of us - old rk26/27 programmers are still interested in doing something with those players? There are for sure good players left out there.
