"Hello, World!" with cc65 in X16 General Chat Posted October 18, 2020 · Edited October 18, 2020 by geek504 24 minutes ago, Ender said: Kernal routines start with "FF" and on the X16 $AB1E would be in RAM After some Googling, I found that STROUT is found in BASIC ROM on the C64 ($A000-BFFF). It's part of the BASIC PRINT command that outputs a string. Commander X16 BASIC ROM is found at $C000-FFFF in Bank #4. I need to find out the address of X16's STROUT and how to JSR to that address... maybe that FARJSR subroutine? Further analysis of X16 BASIC ROM source code, I found the start of STROUT routine in ~\x16-rom-master\basic\code7.s but it doesn't give me an address.
