Arkanoid bootleg on Block hardware set 1 with potentiometer modifcation

This set come from a working pcb.Game differences are:none.
Hardware info: same as used by arkgcbl set
Rom definition:
ark16mod.6e part of main program.Rest of eproms are the same of existing set (arkgcbl)
Eprom is 27256

Note: code was been modified for use of potentiometric control instead of the spinner used by other original and bootleg sets.The pot. that must be used is a 5k Variable Resitor as specified in the schematics of Atari Breakout manual.
Controls tested by using of an Atari 2600 paddle controller with internal original 1M VR replaced by the 5k VR specified above.
Note 2: by testing dip switches i've found that SW1 OFF=table,ON=upright cab and SW2 OFF=1C-1C,ON=1C-2C like DSW of japanese set.So DSW definition reported in the driver for SW1 and SW2 of this set (arkgcbl) is wrong.
