Funhouse Pinball – Rom Upgrade Chip

Versions above L-5 use a larger eprom, and your game needs to be jumpered correctly depending on the version/chip size.  See WPC Jumper Settings

****You must use CPU vL-5 or lower if you have a prototype machine or other machine that has a Sys11 soundboard.****
****You must use Sound vPA-1 if you have a prototype machine or other machine that has a Sys11 soundboard.****

How do I know if I have a prototype / sample machine?  Here is a guide on some of the differences: https://www.flippers.be/funhouse_prototype_guide.html

NOTE: This game ROM requires a 2Meg EPROM. To use a 2Meg EPROM
in your game, make sure that your CPU board is jumpered
correctly as follows:

This ROM version works best with a modified L-2 sound ROM.
With this special L-2 sound ROM, the Enter Initials and
Jackpot lamp effects are enhanced.

The sound ROM checksums are as follows:

NOTE: It is NOT necessary to upgrade U18 in order to use the L-9
game ROM. This modified sound ROM, in conjunction with the L-9
game ROM, provides an enchanced light show for the ‘enter
initials’ display.
