Just wondering, has anyone tried to make a high score save for the Midway card rack system 1 stuff? (Gorf, Wizard of Wor, Space Zap, Robby Roto)

thanks,
Mark

Robby Roto does save scores....

Gorf/Wow both have the memory write protect circuitry to make HS saves possible, but didn't put a battery on the board, and clear the HS table at boot.

I started looking into code mods for gorf a while back, but the code is wretched to read through, since it's obviously compiled code rather than hand-written assembly.

There's no actual 'startup' procedure like most games have... if you reset gorf, it just restarts on the current level, instead of going to attract mode.... it's quite sloppily coded.

In any case, adding HS saves would probably require replacing the ROM board entirely, but considering how crappy the sockets are on those boards, it's not a bad idea anyway... heh. Of course I made replacement ROM boards about 5-6 years ago to fix my robby roto, so at this point, it'd just be a matter of hacking the code -- but I doubt anyone wants to pay for a complete replacement ROM board,and will expect a $45 kit like all the other high score saves, so it hasn't been a particularly high priority.

I think you're right..Gorf fans like myself probably wouldn't want to shell out for a new board that just saves scores, but probably would if there was something else that could be offered. Multigame (I'm guessing not just a ROM board swap?), etc? Dunno... I guess that's the problem.

The game boards are different too, so you can't just do a ROM swap...

There's not really enough room in the card cage to do a plug-in CPU replacement like most other kits...
