Hello Adam, I think you're supposed to take our crt.s and modifiy it to your needs with the missing jumps. https://sourceforge.net/p/sdcc/code/HEAD/tree/trunk/sdcc/device/lib/z80/crt0.s
Assemble it and then link it with the rest of your application. Maarten > Hi, > > I'm developing a program in C for the Z80 and compiling using SDCC.
