Hello ! Sorry for my bad English. I am a programmer from the Czech Republic. I have programmed games such as: - Pacman labyrinth - Space invaders battle - Ufon - Ninja-help-icopter - Robbery - Fire fighter Tobik - ZdendaZuma I. - ZdendaZuma II. (with 7 datadisks) - Multijoy roulette for 17-players (16 players play with a joystick via multijoy and the last one on the keyboard as a croupier) - Bombeeno - Atari hotline - Dark City Road - Greedy bat - Robot and Minion - Tetris T - ... I confirm that I wrote all these games myself, every one byte. I'm writing this mainly because of the ZdendaZuma-Datadisks, so that no one asks if I used Montezuma's original code. No, I didn't use the original code, because I can't read other people's code. If someone comes to the Czech Republic to Cesky Budejovice, they can view my complete source codes :) I tested teh game on the original Atari 800XL (Drive 1050) without any modifications - all worked fine. Also from old AVG Cart all worked fine. When I tested the game on the original Atari 600XL with new SUB AVG Cart, sometimes option SETTINGS / POKEY EMULATION needed to be OFF. Game requires disconnected BASIC - so press OPTION when you start tham. This datadisk contains 40 new original rooms, and again - this datadisk IS AN INDEPENDENT GAME. I programmed all of this because I think that the original Montezuma is the most beautiful game anyone has ever made - and with this my game I wanted to express my admiration and respect for the author of how much I loved the original. Attention - this game saves score and loads rooms from disk, so if you play it in an emulator, set this ATR to R/W in drive ! I would also like to point out that there are about 110 rooms in the original Montezuma - but many rooms are used even 8 times - while I only have 40 rooms in each data disk, but EVERY ONE IS DIFFERENT - so I have more rooms than the original ! I am also sending a complete map of the game for the sake of interest :) IMPORTANT INFO - this datadisk is complete made my son Tobik in my room-editor. And notice - all my datadisks need to be run from disk "D1" !
