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!

I’ve been playing around with the MAME debugger recently. I loaded up Tinkle Pit, a cute, simple (at first…) maze game and started playing around with altering memory values. I found what appeared to be the value for the current game mode, and after poking it for a bit, I came across an odd screen…

News was posted today of the finding and dumping of an unreleased vertical shooter by Sega and Santos for the System 18 arcade hardware, called Hammer Away.

This is a fascinating older post made by the NYC Resistor group detailing the technical data behind the images left behind in the Apple Mac SE ROM<. As the ROM only used 89kB of the available 256kB, the original development digitized pictures of themselves and hid them away in the remaining space. The article goes into some interesting details about the image format and CPU opcodes.

Damian Ward has also posted some nice shots of the images on hardware: here, here, here and here.
