Ms Pac-man freeplay/high score save

[philmurr]

Someone recently asked me if I'd done a freeplay / high score save kit for Ms Pac-man. Although I did high score save for Pac-man a few years ago I'd never looked into Ms Pac-man, which I guess I should have as they share a lot of code (and there's a full disassembly of Mr & Ms Pac-man code out there which helps).

So a few hours later here it is. It wasn't just a straight copy of my Pac-man HSS code as there are a few routines that are different, but it didn't take too long. Gives the following features:-

• Selectable freeplay, maintaining attract mode (also lets you use coined option)
• Easy and hard versions (can be selected on power-up, and remembers your previous selection)
• Saves high scores on power-down
• Different high score tables for easy and hard versions
• 3-letter initial entry when you get a high score
• 10 position high score table
• Reset high score table on power-up via joystick movement

Runs on my standard Z80 single ROM/HSS board (if you have a single chip SBC) or my updated Z80 board with ribbon cable extension which works with the separate SBC board.

Not much else to say, other than photos of it running are attached.
