v0.2 Beta: Breakpoints don't seem to work at all

[ricknun]

Start the program and click on the BR key. The display shows "FULL!" instead of being able to set a breakpoint. If there is a workaround please post it as a reply to this issue. As is I think it makes the emulator of little use for developing ET-3400 programs. I am using a Windows 10 PC and program v0.2 Beta.

I looked into this issue by reading the ET-3400 Monitor code listing, because I really like this emulator and really want breakpoints to work. I found "FC46 CE 00 E2 ... BKSET LDX #BKTBL-2" at the start of the "set a breakpoint" routine. In the version 0.2 Beta emulator, using "EXAM FC48", shows F2 at that address instead of E2. The ET-3400 Monitor code has an error in it. I changed that one byte in the .exe file using the XVI utility and now breakpoints seem to work. The hacked v0.2 Beta executable et3400_RN.exe(.txt for GitHub) is attached. Finding this was fun and brought back feelings of hacking assembly code so many decades ago.

Edit later: This workaround allows a breakpoints to be set that appear to work, but then saving a .brk breakpoints file saves an empty file instead of saving the breakpoint information. So breakpoints in the emulator still need attention.
