- Fixed some bugs in the emulator's assembler.
- 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.
