Alex,

let me address both of your problem reports here:

1. "List file has been modified":

I assume that you launch SXSim from the SX-Key IDE by clicking the IDE's SXSim button. In this case, the IDE re-assembles the source code to make sure that the list file is up-to-date, and then launches SXSim with the command line containing the list file name. SXSim then checks the list file's time/date stamp if this file is "younger" than the associated SIM file it has saved before. When this is the case, the "Restore Breakpoint" dialog is opened, as the breakpoints stored in the SIM file might no longer match in case you have removed or added instructions from/to the source code.

If I got you right, I assume you want to test a program with SXSim, switch back to the SX-Key IDE from time to time (or by accident), and then return to SXSim. You can do this by clicking into the IDE window (or hit Alt-Tab). As I have defined the SXSim Commands window to always stay on top, this will hide parts if the IDE's Edit window but you should be able to return to SXSim by either hitting Alt-Tab again, or by clicking into the SXSim Commands window. In this case, you should be able to continue the simulation from the most recent point on. When you quit SXSim to restore the IDE windows, and click the IDE's SXSim button later, SXSim is re-launched again, and it re-loads the list file, so you can't continue the simulation but have to re-start it again. To avoid this, I could add an option to "freeze" the current status of all SX registers in the SIM file so that they can be restored for the next session. I'll add this to my TODO list.

2. Undoing shadow registers

Congratulations - you have found a bug! Thanks to your report, I found that the shadow registers and the FIFO were not always correctly restored when the "Back" button was clicked. I have fixed this in the meantime, and will release a new version soon.

Please stay tuned...
