BombJack Save High-Score
Bombjack is one of the real classics, I've spent a lot of time playing this game. But it was David Haynes who suggested adding it to the list ! Have a look at Dave's his website with the awesome domain name, www.bombjack.org.
This hack is similar to Mr.Do in that a socket needs to be added if the RAM at a4 is not socketed. A local supplier had the ST equivalent to the Dallas part so I gave it a try, so I can also reccommend the M48Z02 as a substitute for the Dallas part ( but it was more expensive !).
Only one game ROM needs to be modified to save the high-score table.
