I have added two new images to the “Putting it Together” page (here) that now implement the NVRam that could be used with the hardware. The games that support this are “Gorf” and “Wizard of Wor”.
These versions will allow you to save the high scores to the SDRam card whenever they change.
To do this you need to press the OSD button before you switch off. (I prefer to do this on the attract screen) and if the scores have changed since they were loaded you should get a “Saving ….” popup before the normal menu appears.
As a side line, when in the OSD menu the game will now pause. So if you need a quick drink (or something else) in the middle of a long session you can affectively use this to pause the game and resume when you return with a second press on the OSD button.
There are a few new DIP settings added to Gorf, so I decided I may need to explain them. For further information see the “Changing the Settings” page (here)
