Hello everyone, it's been a very long time! I'm glad to see this list is alive and well. I hope you all are having a great holiday season! Here's the long sad part of the story: I recently gave up on ever retrieving the original source code to all versions of Dark Mage and This Planet Sucks from the hard drive they had lived on which crapped out on me a few years back. I finally just tossed the drive and got on with my life. So, I fired up distella and started to recreate the source to tps, because: the original 'final' version that Randy Crihfield had burned and sold had problems with too many scanlines that caused some older televisions to roll the screen... Then I did a quick and dirty binary patch for him which took out a whole row of enemies to drastically reduce the scanlines and quick fix the problem... Here's the happy part of the story: I've gotten enough of the disassembly labelled and commented to easily work on it and have fixed this scanline problem (I think)... It still draws more than 192 visible lines, so it might cut off some of the bottom on older televisions, but the overscan is repaired so as to never draw more than the official 262 lines total, so the rolling problem should be gone, while the original number of rows of enemies is back in place... So here is the allegedly 'perfect' version of the game. Feel free to redistribute it at will, and of course any testing and comments are always welcome. I'm thinking of doing a sequel or maybe some other game. I'm pretty fond of twitchy platformers like Donkey Kong and Montezuma's Revenge, so maybe the sequel will get down onto those platforms and control the little goofs...???
