2020-04-17Made both the assembly language monitor, and themrb0nk500
emulator smaller, and faster. I am also starting to make SuBEditor's source code more readable.
2020-04-09Completely changed the assembler.mrb0nk500
It now has a lexer/tokenizer, along with a parser. I have also made the emulator even smaller.
2020-04-02Made the emulator less bloated, and faster.mrb0nk500
2020-03-24Added support in SuBEditor for true backspace, andmrb0nk500
inserting characters without replacing the old ones.
2020-03-17Cleaned up the debug prints in the C port of SuBEditor.mrb0nk500
2020-03-17Revamped the opcode table, made the emulator moremrb0nk500
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.
2020-02-20Finished SuBAsm's screen editor.mrb0nk500
Which I am now calling, SuBEditor.
2020-01-23Start optimizing the emulator.mrb0nk500
I also added a new input testing program called input-3.s, which contains a mostly working editor.
2020-01-10Added GPLv2.mrb0nk500
We're now Free Software!!!
2019-12-24Added support for Indirect addressing modes, and allowmrb0nk500
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>
2019-12-19Fixed some bugs in both the assembly languagemrb0nk500
monitor, and the cursor movement routines for SuBAsm.
2019-12-18Start work on SuBAsm.mrb0nk500
Also added support for moving the cursor arround.
