Could SJLOAD be an option? I figured out that for my purposes (a flash programmer for the Ultimem for the Vic-20) it was easiest to use the standard KERNAL routines, but at the same time ensure that the program works while SJLOAD20 is loaded into the Vic-20 RAM. Linking my code to SJLOAD would certainly have been technically possible. I even started some work towards it, but in the end I decided that a modular solution is cleaner, and removes any doubt regarding copyright license compatibility. (I wanted to distribute my code under the terms of the GNU GPLv2.) The SJLOAD is a bit like a loadable device driver or operating system module. It is not that hard to use the fastloader, as you can see in http://www.iki.fi/~msmakela/8bit/ultimem/#install Basically, it is only an extra step of LOAD and SYS. In the case of the Vic-20, there also is an extra step of enabling RAM in the area where SJLOAD is loaded. Marko Message was sent through the cbm-hackers mailing listReceived on 2017-12-11 15:00:03
