- [NEW] While debugging you can go back/forward in time

- [NEW] Step by step execution with F6
- [NEW] Memory is tagged as code or data while executing, so later it can be properly disassembled
- [NEW] "reg X value" to set the value of X register
- [FIX] IX opcode table had errors
- [FIX] opcodes with two parameters where printed incorrectly on the disassembler
- [FIX] opcodes can't be lager than 4 bytes
