- Started work on implementing the Super VIA emulation.
- Added support for disabling disassembly per
instruction, when in debug mode.
- Did some more work on rewriting the SuB Suite to
work with the new calling convention.
- Rewrote the symbol handling code in the emulator's
assembler, to make it both simpler, and to add
support for arbitrarily deep symbol scopes.
- Added support for arbitrarily deep local symbol
scopes.
For example, to declare a symbol of depth 2, you add
two '@' characters to the start of the symbol name.
In other words, the number of '@' characters before
the symbol name is what determines the scope of that
symbol.
And to use a symbol thats outside the current
scope, you would use the same syntax as using a
struct member, so you would do `global.local`.

I mainly did this to be able to display all 16 main
registers, but also to simplify the debugger.

address handling.
It's now all done using several functions for each
addressing mode, with the result being the effective
address.
I did this to make the codebase cleaner, and more
readable.

It now uses a struct to store the escape sequence.
Before it handles the escape sequence, it parses it,
which includes things like getting any arguments
that are supplied, and getting the mode type.
- Moved the code that handles control codes to a
separate function.
The reason for doing this was because I wanted to make
the escape sequence handling faster, but also make the
code more readable at the same time.
I got the idea to do this from st, a terminal emulator
created by the suckless.org project.

I decided to use keypad now, and create a function to
return the actual key sequences.
The keyboard I/O is also now being handled by the io
emulation function, and not by the main function.
This should get rid of any possible deadlocks.

It now saves the characters of the typed key into a
buffer, and returns each character in the buffer one
at a time, until it reaches a null terminator, at
which point it starts getting the next key.
The reason for doing this was to make getting multi
character keys faster, by not calling getch() for
each character.
The only downside to this is that I have to set a
timeout() for getch(), making it somewhat non
blocking, although the delay is 8 milliseconds.
The next thing I'll probably be doing, is working more
on the SuB suite.

- Fix some bugs with strings.
- Started to refactor the instruction functions.
- Added support for using RS prefixes on the memory
based increment, and decrement instructions.
- Started work on SuBAsm's lexer.
Have fun looking at this, BieHDC. :)

- Moved the large enums, and large tables into separate
header files.
- Added enums for implementing the base extension
- Fixed a bug in the assembler.
- Worked more on SuBAsm.

functions.
I did this to make it more readable, while still
making it fast, due to inlining it.
