Thanks, I was able to start a service. I just can't seem to write data back to the calc. I'm using libticalcs to send/receive the data from the PC side. I opened a connection to service 32767, and am able to send data to the PC. When I send something from the PC to the calc, it sends successfully and I get an ACK packet, but attempting to do an TI_NN_Read() on the calc side just times out. Does anyone know if there's anything special you need to do to make this work?

Turns out interrupts weren't enabled, despite using TCT_Local_Control_Interrupts(). I had to clear bit 7 of cpsr to enable them, but it worked! Now I need to find a way to disable the clock cursor that appears (why is this even a thing? xD)

Hey guys! Does anyone know if it's possible to disable the cursor clock that appears when interrupts are enabled? I have to have them enabled for the USB code to work and I'm running in 8-bit color mode (the OS expects 16 it seems) and it causes a crash when the cursor gets moved off-screen. Thanks!

How do you set the LCD mode? If you use lcd_blit or overwrite SCREEN_BASE_ADDRESS, the OS should not be able to draw on the screen anymore.

Hey, I know it's been a while since this forum was active, but I was wondering about calc-to-calc navnet. I managed to get it working when the calculators are connected but it looks like the os overrides reads from the other calc even if there is a ndless program running. Any help?
