FREE HIGH RES GAMES - ROCK CRUSH AND DANS REVENGE:
The following High Res games are presented here by the author (myself) as freeware. They
will be supported fully on this page. Rock Crush and its follow up game, Dans Revenge were
both written over 12 years ago now and have only recently been rescued and made available
to ZX81 owners. Both games were written in 100% Z80 machine code and featured a Spectrum
quality display resolution on a standard 16K ZX81, without any additional hardware being
required. Both are 'puzzle / action' type games and require good reflexes!
In their time they received several rave reviews in national computer magazines and even coverage on Texas's Radio WOAI 1200 - "Computer Line" program, hosted by John Stewart. The station also ran a competition where they were given out to listeners as prizes.
The games were made available mail-order only and a lot of copies were posted abroad to the States and Canada (as well as here in the UK).
John Stewart is an author and computer reporter for Business News Network in the USA and BYTE THIS on Australia's Triple-M Network.
I made contact again with him recently (after a gap of over 8 years) and amazingly, he said, "I still have ROCK CRUSH and a T/S 1000, although I have not used them for some time!"
"I will pass along your URL on the radio in the USA, also in Australia, and in my new newsletter!"
"I'm glad you tracked me down! Now I have to get out the T/S and load the games!"
He is still interested in this fascinating little machine and needless to say, John is now on the ZX81 mailing list!
Incidentally, John also authors a brilliant weekly newsletter covering all the latest news and developments in the computing industry.

It's an extremely interesting read!
Both these games have been re-mastered by myself, the author, to run under the emulator, almost identically as they will on a real 16K ZX81. Incidentally, this new version (V2.1) runs the games exactly as the original version did!
Update: New Version Just Released - V2.1!
As a lot of people have been asking me recently, as to how the High Res routines actually work, in response, I have decided to document and release a detailed text file on how this is achieved. You can get this now by clicking here!

V3.0 of Rock Crush and Dan's Revenge will shortly be made available (runs at the same
speed on all cpu's and improves performance on XTender). I also plan a V4.0 for use with
XTender2 only. I have had to 'tweak' my games over the different versions to optimise
performance with XTender. XTender2 is capable of running the original code exactly as it
would on a real machine - so with V4.0 it will be back to the original codebase but with
updated documentation etc.
