Re: ZX81 emulator for iOS

Any explanation for the removal? Because the game represents simulated gambling and my Apple Developer account is registered to an individual instead of an organisation their rules do not permit it and they rejected updates until it was removed. I’m not prepared to register a company, then apply to...

Hi Stefano,
Off topic - can I include your 1K chess port into my iOS ZX81 emulator?
Thanks,

Re: ZX81 emulator for iOS

It’s been a while since I’ve posted on this topic thread. A new update (v1.6.0) has just been released on the App Store, which incorporates Chroma colour support. The main limitation still exists of not being permitted to load programs except those already included with the app. The Apple developer ...

Re: Russell J Marks - is anyone in contact?

I finally made contact with Russell: “Well I haven't done much programming for some years now, I kind of mostly trailed off with that around 2005/6. To be honest I was finding it a lot harder to do as I got older, and when it was just a hobby really it's hard not to drift onto other things. Probably...

Re: ZON X-81 vs ZON X

Hi Dim, After you kindly responded in the ZX81 Owners Facebook group I started looking at the notes on the schematic and with the help of Sirmorris testing using his real ZON X-81 the following conclusions were reached for the port addresses: A0 to A3 are always high A4 can be low or high for ZON X-...

Russell J Marks - is anyone in contact?

Hi Folks, I'd like to get in contact with Russell Marks, the author of the Z81 emulator (his code base was a starting point for other modern emulators): http://www.svgalib.org/rus/z81.html He doesn't seem to have been active since October 2004 according his change log. And his email address in the f...

ZON X-81 vs ZON X

Hi AY Gurus, I’m planning to add ZON support to my emulator. Looking at resources like: https://k1.spdns.de/Vintage/Sinclair/80/Peripherals/Bi-Pak%20ZON%20X-81%20Sound%20Module/ https://k1.spdns.de/Vintage/Sinclair/82/Peripherals/Bi-Pak%20ZON%20X%20Sound%20Module/ and then the source code for Eighty...

Re: Copyrights for New Generation Software games (e.g. 3D Monster Maze)

I was given the email address of Mr Caen the CEO of Interplay a couple of days after my post. Unfortunately, there was no response nor automated delivery failure message. Either after all these years they cannot confirm ownership or it is not in their interest to respond. I hope that the portfolio o...

Copyrights for New Generation Software games (e.g. 3D Monster Maze)

Posting here the result of my search for answers with the hope that someone else might have information to get past an impasse. Since 3D Monster Maze is such as a well known and loved title I’ve been looking into obtaining permission to bundle it with the iOS emulator app. If you read my previous po...
