your posts on this subject are becoming borderline spam, it seems impossible to mention Namco hardware without you reposting about this.

I don't want this thread to end up being dragged down the 'why isn't Namco networking emulated' route. It is also not the place to post random decap requests (note, it's entirely possible the said device can't even be dumped, not every custom has ROM)

I was giving an update on the status of Galaxian 3, that's all.

I've already spent YEARS avoiding doing work on any kind of Namco hardware due to multiple people who would jump on the slightest mention of it and start spamming about it, so it's something of a sensitive subject.
