Another patch that you will need you to replace a ram chip, its the 8218 ram chip at H1 (next to the four program roms) with an NV version such as DS1220, M48Z02, U63716DC etc.
The patches below are compatible with the Mame rom set DoWild.
To reset the high score table enable freeze, ground pin 6 of the edge connector (component side), when powering the board up.
As with all my High Score Patches, please post a reply or click thanks if you find this patch works for you.
