Hi.
Wow! That's more praise than I feel worthy of :O Thank you very much. Your words means a lot to me.
You are right in that these PDFs don't earn very much. I am always interested in what internet creators earn, and maybe some want to know what I have made on these. I have made a little over $400-after tax-since February, which I think is actually very good for something like this. I feel pride in that there are people willing to pay $10 for a PDF I made/copy/pasted/whatever. I find it crazy that someone find it worth so much.
The reason I make these PDFs is that I like it. I like reading up on a system and searching for information about it, editing and designing the layout of the pages. It does take a very long time though, and I'm not good at time managing stuff in my home life. I often get very obsessed when I'm doing a project and it eats up much of my time (I'm similar when it comes to video games, which is why I steer clear of online games :p I only play games with an ending).
I agree with the Alexandria library. Insane to think on what kind of wonders and information we lost.
I have promised (for the eight times probably haha) that this was my last book project. I hope I can keep the promise this time :p but it's very difficult when I get the itch (no pun) to start another project. A lot of the consoles you listed have been on my mind. I would love to continue from the FM-7 to other Japanese home computers, but they are a lot of work and because I don't know the language a lot of mistakes will occur. The PSP would also be fun, or the DS or Wii. But their libraries are huge. And the "forgotten systems" you lists have also been on my mind.
Thank you very much for your words and have a very great Christmas and new year!
From Daniel :)
