cisc-0.2 - An emulator for the Sux instruction set.

2020-05-18	Did alot of stuff while I was up at the family trailer.	mrb0nk500
	- 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.
2020-05-09	Added support for single quote marks to the emulator's	mrb0nk500
	assembler. Single quote marks works in the assembler just like they do in C, except that it only supports a handful of escaped characters, like '\n', and '\r'.
2020-04-27	Added support for including source files to the	mrb0nk500
	emulator's assembler. And removed three pointers, and the linewrap table from zero page, in SuBEditor. I moved the linewrap table to address $1000. And because of finally adding include support to the assembler, I can now start work on SuBAsm!
2020-04-19	Removed most of the commented code, and optimized the	mrb0nk500
	emulator some more. I optimized the emulator by replacing the main loop from a conditional while loop, to an unconditional for loop.
2020-04-17	Made both the assembly language monitor, and the	mrb0nk500
	emulator smaller, and faster. I am also starting to make SuBEditor's source code more readable.
2020-04-09	Completely changed the assembler.	mrb0nk500
	It now has a lexer/tokenizer, along with a parser. I have also made the emulator even smaller.
2020-04-02	Made the emulator less bloated, and faster.	mrb0nk500

2020-03-24	Added support in SuBEditor for true backspace, and	mrb0nk500
	inserting characters without replacing the old ones.
2020-03-17	Cleaned up the debug prints in the C port of SuBEditor.	mrb0nk500

2020-03-17	Revamped the opcode table, made the emulator more	mrb0nk500
	efficient, and ported SuBEditor to C. I revamped the opcode table to add another prefix bit for the addressing mode, finally giving access to all addresses, without wasting any bytes. I made the stack based operations more efficient, by sort of applying Duff's device to it. And I ported SuBEditor to C, to make it easier for me to figure out how to implement SuBAsm.
2020-02-20	Finished SuBAsm's screen editor.	mrb0nk500
	Which I am now calling, SuBEditor.
2020-01-23	Start optimizing the emulator.	mrb0nk500
	I also added a new input testing program called input-3.s, which contains a mostly working editor.
2020-01-10	Added GPLv2.	mrb0nk500
	We're now Free Software!!!
2019-12-24	Added support for Indirect addressing modes, and allow	mrb0nk500
	for use of the B register as an operand, for ALU based instructions. This allows for both low code size, and high performance. This means we can save upto 9 bytes, by just using the B register for ALU operations, rather than using a memory address. The indirect addressing modes, give Sux the abillity to now use pointers. Hope you guys have a Merry Christmas! From mr b0nk 500 <b0nk@b0nk.xyz>
2019-12-19	Fixed some bugs in both the assembly language	mrb0nk500
	monitor, and the cursor movement routines for SuBAsm.
2019-12-18	Start work on SuBAsm.	mrb0nk500
	Also added support for moving the cursor arround.
