2020-08-17- Fixed some bugs in the emulator's assembler.mrb0nk500
- Simplified the effective address functions. - Made SuBEditor a bit faster. - JSR, and RTS now support using the RS prefix, which is used to specify the return address size, with an RS prefix of 0 being a return address size of 64 bits, rather than 8 bits.
2020-05-29Make JSL, JSR absolute, and remove RTL.mrb0nk500
The reason for doing this was because JSL, and RTL are redundent, as they both do the same thing as JSR, and RTS.
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.
2020-04-02Made the emulator less bloated, and faster.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.
