    Update inx / ins / des / lsr / inc cycle accuracy

    This commit fixes instruction timing inaccuracies in the cpu68 core that
    were causing software-timed pitch loops, such as the 'humanoid fall'
    sound in Robotron and Defender, to play too quickly and at too high a pitch.

    - lsr / inc: Used in the tight inner loop of the sound generation calculation.
      By injecting a stall_write_state before the write cycle, these extended/indexed
      single-operand memory instructions now correctly take 6 cycles instead of 5,
      slowing down the PCM pitch loop to match real hardware.

    - inx: Heavily used in the outer loops to iterate through sound calculation pairs.
      By transitioning to stall2_state instead of fetch_state, inx now takes the
      accurate 4 cycles instead of finishing incorrectly in 2 cycles, further
      slowing down the pitch generation loops.

    - ins / des: Fixed alongside inx for structural cycle-accuracy completeness (2 to 4 cycles).

ROM Files Instructions

ROMs are not included! In order to use this arcade core, you will need to provide the correct ROM file yourself.

To simplify the process .mra files are provided in the releases folder, that specify the required ROMs with their checksums. The ROMs .zip filename refers to the corresponding file from the MAME project.

Please refer to https://github.com/MiSTer-devel/Main_MiSTer/wiki/Arcade-Roms for information on how to setup and use the environment.

Quick reference for folders and file placement:

/_Arcade/<game name>.mra  
/_Arcade/cores/<game rbf>.rbf  
/_Arcade/mame/<mame rom>.zip  
/_Arcade/hbmame/<hbmame rom>.zip
