Did anyone here still have a copy of version 1.0 of the original DX-Ball?

I've searching through the internet, but I can't find it. :(

If you're asking why I'm looking for it, because I want to discover the cheats and secrets that only works in the initial version.

I was able to track down the original DX-Ball website from the internet archive, but it seems they only have a copy of version 1.07. What kind of cheats / secrets were you thinking about ? The only ones I've heard of are CTRL+F3 to get the laser guns, CTRL+F4 to expand the paddle, and CTRL+F1 on the title screen to access the board editor.

In this article, it says that there are more cheats like instant extra life, Fireball, Thru Bricks, and many others.

None of those work on 1.07 nor 1.09.

So I assume that those additional cheats are from the older version, or... is it a fake code?

I'm pretty sure those cheats are fake. Cheat sites tend to be ridden with false information, like hoaxes that incline the player to accomplish something difficult for a given reward, only to have them waste their time in the end. It's also possible those codes might stem from a trainer, having ended up out of context. Either way, if you still feel uncertain, you could try get in touch with Michael about it.

I think you're right, and seems the author appear to be an anonymous, unresponsible person that post misleading codes...
