I've been messing around with magazine type-in games again these last few weeks, at the minute I'm on Compute!. I came across Meteor Storm and couldn't get it working under XE OS. Tried all sorts but it wasn't happening. MC was the only way, but my MC-fu is weak. Several hours later and I've found a memory move routine that works backwards (necessary in this case). Several more hours later and I've got it working after figuring out how to do addition in MC (very painful). A couple more hours and I've integrated it into the game and it is working fine, to my eternal joy. Fix notes: This game refuses to work on XL/XE systems as originally printed. The reverse scroll of the meteors is achieved by fooling the OS into thinking it is in mode 0 when it is actually in mode 1, and then printing an insert line character at the top of the screen. While this works on the 400/800 OS, under the XL/XE it does something evil to the display RAM, corrupting it and making the game unplayable. To fix this, I have added a small MC routine to replace the print of the insert line character. The MC routine detects the address of the start of screen RAM, and copies lines 23-3 to the next line down in reverse order. A normal memory move wouldn't have worked as the source and destination overlap. And here they are; bootable ATR (Basic required), and the BAS and LST (as a TXT) files for your pleasure. Enjoy! PS, Atarimania are more than welcome to add this to their database as a fixed version. Meteor Storm (XL fixed).atr METEORXL.BAS METEORXL.TXT
I recently upgraded (yet again!) to Omnipage Professional 18 OCR software from Nuance. I started out in the 90's with Caere's Omnipage 2 or 3, so I'd hate to think of all the $ I've spent on the upgrades. But it's finally paying off! With every upgrade, the OCR of old magazine articles and programs got better and better. The articles themselves pose no particular problem, since a "typo" here and there is easy to tolerate. But OCR'ing programs has been difficult. The really old dot matrix listings are still error-prone, but "regular" typefaces are now easily recognized. I still would not describe it as "fun," but now when I need a program from magazines like Compute! that had many issues without disks, it's no problem. -Larry
