Snowdrop OS assembler and debugger
Versions 22 and 23 have been important for Snowdrop OS because they introduced an assembler and debugger.

In version 22 I have created Snowdrop OS's x86 assembler, because of three reasons. First, I wanted to have a low-level programming platform to complement Snowdrop's high-level BASIC interpreter. Second, I wanted to have faster access to hardware when interfacing with the circuits I've created. Third, I had never created an assembler before, so I was curious.

In version 23, I have created a debugger to accompany the assembler. It is a machine-level debugger with features including: breakpoints, memory watch, view listing.

The debugger is small in size, at around 10kb. The main reason behind this is that it relies on assembler-generated listing files to display source code. This means that it does not need its own decoder to translate bytes to assembler mnemonics.
