The way it works is that of the 38 pins on a HuCard, the middle pins
(specifically 15-17 and 19-23, where 18 is ground) are flipped between
US and Jp cards. Either way, the converters like the Kisado (and
Purple Barney, diving board, Mirai, etc) merely "flip" these going from
the HuCard to the hardware. The problem Bt mentioned is that US
HuCards have a lockout where it polls the processor to check the region
of the hardware, causing US HuCards to not work on non-US hardware
(although Japanese HuCards work fine on US hardware with the
converters). To defeat the region block, you must lift pin 29 on the
Hu6280 processor and ground it to the board. This allows you to use
the US cards on any Japanese unit. The only game I've ever seen
affected negatively by this mod is Aldynes for the SuperGrafx. This
game hangs during the attract mode, but works fine if you start the
game before advancing in the attract mode.
The pin 29 mod is simple enough, although that tiny little pin is quite
sensitive.
If anyone is in need of this mod or the hardware region mod (meaning
installing the region switch to surpass the use of the Kisado or other
converter), please let me know and I can provide it.
On a side note, any one looking to sell? Let me know that too!
