Is it strictly forbidden?

I have draw a picture about the hardward.

Anybody dose not connect the two items in real world.

The game machine would not work, and alarming error code with 66.

When I add the game in MAME, alarming error code with 66, I can not ask anyone to solve it?

I found two bugs with MAME, Can not I tell any body? The serious bug is the chip i8297, Array bounds with fifo ram!
define is 8, and use is 16.

I am a newbie about mame dev, I thought it's my fault with 8031 Port, So I ask for help.

I have not any interest at cabinet or anything transfer.

I am sorry for my English level. I try it in Chinese.

因为i8279的bug，导致作为新手的我以为是i8031的端口有问题，因为添加给MAME的游戏启动报错是i8031的错，错误代码66，该端口连接的硬件错误，导致游戏不能运行，所以求助。经过核实，最后确认是mess团队提供的i8279的问题，里面定义8个字节的fifo ram，运行的时候是16个字节，导致数组越界。

为了排查这个问题，我拿游戏板，核对线路，草图如上。

and we would love to see the code which fixes the bugs you reported, of course
those would be added (with credit to you) in next release
