After the bnez and beqz instruction, regardless of register and offset used, 0xCCCC is inserted.

For example, for this editor code:

This code is shown in debug mode:

We are currently using the x8086 memory model, and just using the arena segment.
Need to change it to the RISC-V memory model.

This command should write the contents of x1 into the address that comes 128 bytes after the address x2 point to, but instead, it writes it exactly to the address x2 points to.

I also tried to use 64 instead of 128 but the same behavior was observed.

Only RV32I without crc-related commands

when i try to type a special character, for example "&" or ">", it is shown as it's html character tag. for example ">" is shown as ">"

The text editor skips over empty lines and does not show them. when I tried to write a comment at the end of the survivor code the text jumped above.
correction: this happens when the compiler throws a warning, problem or debug information of any kind

As it says in the official specifications:

C.JR (jump register) performs an unconditional control transfer to the address in register rs1. C.JR Rexpands to jalr x0, rs1, 0.

Despite this, using jr will behave like j, jumping by the value in the register from the current location.

When writing pseudo-instructions that expand to more than 1 instruction, the debugger gets confused and doesn't show it correctly, and maybe even doesn't run it correctly.
For example:
li x1, 0xcafebabe

This way we will avoid duplicate efforts and get also new ideas for the roadmap

If some 32 bit command is written partially at 0xFFFD and partially at 0x0000, when the survivor's PC reaches 0xFFFD and the survivor will try to execute the command the simulator will crash.

It is hard to associate the code with its location in the arena.
Coloring it in the same color will ease the understanding
