I recommend selling your copy and buying one that’s already complete. It’s a serious PITA to find manuals separately, even for common AES titles.
For sure, but I'd figure I'd throw it out there anyway. Got nothing to lose...
Honestly, I only own a handful of AES games. The bulk of my games are MVS and as more time passes I'm tempted to move exclusively to MVS and part ways with my AES games. Of course there's a part of me that is resistant to the idea. The AES was that dream system for me as a kid, but growing up poor it just wasn't gonna happen.
