Mentioned on the Discord but just to mention here, works great!! I was able to both confirm good working RAM as well as testing a known bad configuration which previously was passing basic RAM tests. The ROM was able to properly detect the bad RAM. Nicely done!

I like the layout. This would make a good prop screen.

Functionality has not changed much, but the code has been converted to CA65, I have switched from a build script to a makefile and I have manged to create a ca65 config file to use for building the binary.
All of this is to enable the Memory diagnostic ROM to be included in the official kernal.
I have made a pull request to the
x16-smc and one to the official
x16-rom
If these requests get accepted, it will mean that the system can boot into memory diagnostic by holding the power butten pressed when powerering the system on.
It will also be possible to jump directly to the memory diagnostics from BASIC by doing:
BANK0,16:SYS$C000
