Hi,

Just want to share some information about the IPDB n 4431 pinball : THE MANILAMATIC TOP SOUND 

This pinball was present at the BGS 2019 (Bourgogne Game Show) and we have made a dump of the ROMs CPU.

Some pictures and a video are also available here :

The CPU board is different from the GTB SYSTEM 80B, as its a specific model built by ManilaMatic. This is a COMBO board, integrating both the CPU and the DRIVER boards.

The two ROMs are also different from the GTB ROCK, as this PINBALL use not one 2764 but TWO !

I dont know the exact mapping in the 6502 space, but it appear that the second ROM is mapped at $20003FFF. Code is near the ROCK but slightly different.

Probably, the first ROM is only mapped at $E000..$FFFF as is contain the reset/irq vectors.

Not sure that the space $1000..$17FF is decoded like on GTB 80B boards, because Manilamatic dont use it.

Board use the same addresses for RIOTs, NVRAM, RAM as GTB 80B.

Kind regards.

                  Thierry.
