Happy New Year! As promised, here is the writeup on the classic Cave shooter, Donpachi. I’ve decided to do something a little bit different here. Instead of spending so much time writing out the technical details of my findings, I’m instead just providing an overview and MAME cheats to access them. I’ll do the same with the Dodonpachi which will follow later. Later this year I’ll finish up with a detailed technical article about both games. I’m doing it this way in part because the two games share a lot of code (as DDP was clearly built off of DP), and in part because I’ll never get this article out the door in time otherwise. I think there’s a bunch of interesting things here that fans of the game will want to play with, so I’d like to get it published sooner than later.

But I still enjoy disassembling and researching old software, and there’s still a backlog of content to finish writing and post, so the site is definitely not dead!

And speaking of backlogs, a few months back my friend AJ on twitter asked that I take a look at Neo Bomberman for the NeoGeo after spotting some suspicious text strings. I started the initial disassembly right away, but didn’t give it a serious examination until recently…
