Here are the versions we have:
arkanoid The earlier revisions. They each differ in the country byte. These
arkanoiduo versions work fine both the bootleg a75-06 MCU rom and the
arkanoidjb genuine decapped Taito A75-06.IC16 M68705 MCU.

arkanoidu USA version. A later revision, code has been inserted NOT patched.
The 68705 code for this one was not available; I made it up from
the current A75-06.IC16 changing the level data pointer table.

arkanoidj Japanese version. Final revision, MCU code not dumped.
arkanoidja Japanese version. A later revision with level selector.

Someone[who?] made a placeholder MCU for this set based on the
bootleg A75-06.IC16 by changing the level data pointer table.

arkanoidjbl Bootleg of the early Japanese version. The only difference is
that the warning text has been replaced by "WAIT"
This version came with its own 68705p3 MCU ROM which is based on
the original Taito one.
the original Taito A75__06.IC16 one, which the pirates must have
extracted somehow.
arkatayt Another bootleg of the early Japanese one, more heavily modified
arkblock Another bootleg of the early Japanese one, more heavily modified
arkbloc2 Another bootleg

The following MCU images were tested on an original Arkanoid PCB using sets
'arkanoid', 'arkanoidu' and 'arkanoiduo' and work as expected.
(1) MCU image with CRC 0x389a8cfb <- this is a deprotected copy of the original Taito A75__06 MCU code
(2) MCU image with CRC 0x515d77b6 <- this is a blackbox-reverse engineered bootleg MCU written by pirates

An MCU found on a Tournament Arkanoid PCB was an unprotected type MC68705P3
and when read the CRC matched (1). So we assumed the MCUs for Arkanoid and
