Still hacking around with MAME games, and I’m having a blast!

There’s a request on mamecheat for Pocket Gal Deluxe, and I figured I’d give it a go. I played around for a bit, then discovered a nice, juicy string table with some intriguing bits of text. After a few hours of working backwards through the disassembly, I discovered a number of interesting tidbits in the data!

The MAME hacking continues! Momoko 120% is a platform shooter with an interesting history. I’ve always enjoyed it and have begun a full disassembly of the code, partially to learn Z80 assembly and also, as always, to look for any bits of leftover or unused data. And find something I did!
