Thanks for your response, How can I "send a command to the uCom chip" ?
Thanks to Diaftia mod, in the user menu I have a direct access to coreplayer and it starts correctly. But it doesn't sound !!!!
I've been trying to find time to answer that very question. Looking at the service manual I know it's hooked up to one of the Navi's serial ports (UART2), but I still need to add additional code to HaRET to be able to trace the memory writes and reads the CPU does to send commands to the uCom via the serial port. Which thanks to work, I just don't have time for these days. ![]()
