I start the tests with the 4 in 1 "27C256_Phoenix_Hero_Kangaroo_Ms pac man" and only Hero don't worked, so I separeted the 4 games and replaced "Hero" with other "Hero" from the 4x1 dump of the thread above, so the 4 games work.

So the roms I sent you haves the same bankswitch scheme as that weird cart?
Then The other ones I sent you might work too.. All of them works in the same board I tested here, so I think if one of them works all other must work too.

I used the pcb below...
The friend alex_79 member here in the forum, traced the schematics.
I converted this circuit to use a 27C512 adding two more switches and now it is able to run eight 8K games. But the bankswitching is the same.. It was not changed..

Are you Brazilian @pcrock, if you can help me because I don't understand electrical projects and schemes?
I am too
