GalagACE v1.1 for the TI-84 Plus CE and TI-83 Premium CE calculators Original TI-83+ game by Dream of Omnimaga (2002) TI-84 Plus CE remake by Dream of Omnimaga (2016) https://djomnimaga.music-2000.com DESCRIPTION Back in Spring 2002, I made a Space Invaders clone that eventually became part of the Omnimaga Pack 25 Games in 1 collection, for the TI-83 Plus and TI-84 Plus. 14 years later, I decided to remake it in hybrid TI-BASIC for the TI-84 Plus CE and TI-83 Premium CE, under the new name GalagACE. The name GalagACE is basically "Galaga", "Ace" and "CE" combined together. The game uses grosged's Sprite library and features various enhancements over the original, such as bosses, more variety, multi-bullet shooting and better graphics. INSTALLING *WARNING: If you use OS 5.5.1 or higher, then you must download ArTIfiCE at https://yvantt.github.io/arTIfiCE/ and ASMHOOK at https://github.com/jacobly0/asmhook in order to restore ASM functionality, required to run the Sprites library below.* 1) Before installing the game, you must download the Sprites library by grosged at https://tiplanet.org/modules/archives/download.php?id=539203 (or https://tiplanet.org/forum/archives_voir.php?id=539203 ). 2) Send SPRITES, CLSCREEN, BACKHOME, SETTINGS, PRINT and PALETTE to your TI-83 Premium CE or TI-84 Plus CE RAM. 3) Send GALAGACE to your calculator RAM or archive. 3) Launch prgmGALAGACE from the PRGM menu. *NOTE*: For optimal speed, make sure that your RAM is as high as possible and that you don't have too many programs on your calculator. CONTROLS -Press any key to get past the title or Game Over screens -CLEAR: Exit game (NEVER quit the game using the ON key!) -Left and Right: Move your spaceship -2nd: Shoot (you can shoot three bullets at a time) GAMEPLAY If you ever played Phoenix, Galaxian, Galaga and Calcuzap, then this game should be self-explanatory. Basically it's a 2D space shooter and you must defeat all alien ships. Each destroyed ship and target gives between 100 and 900 points. There are 18 enemy waves and you start with 5 lives. If you beat the game then you can restart with 1 life, but you keep your score. KNOWN ISSUES -Sometimes, enemy bullets appears at weird locations. It's because the game will try to find an enemy ship to launch bullets from only 5 times before the randomizer finally gives up. DISCLAIMERS -I will not be held responsible for any damage caused by this software. It shouldn't cause any crash, though, and it was tested thoroughly to make sure it won't. -This game will not run on the TI-84 Plus C Silver Edition nor on monochrome models. -You can re-use the source code in your game. Just make sure to give me some credits for the idea.
