OP here. Sorry if there was confusion. I came across your repo and was giddy with excitement to see it and wanted to immediately tell the world! :-) This book was a big deal for me in the late 1990s, still working as a game programmer. My copies were lost or loaned and I think I heard angels sing (or tracker/chip tunes?) when I discovered your repo. ;-)

I suffixed the headline "2019 V1.1 Release", trying for some clarity, since that was the most recent event I saw in the repo. Then it was re-headlined by someone else because that was also, apparently, confusing. Sorry! But THANK YOU for your work!
