More Information Pokemon+ [[Screenshots] [Reviews]]
Pokemon + add-in is functional and very Casio OS looking interface to view and calculate evolution of your Pokemon for Casio Prizm/FX-CG calculators. It's current functionality in 3 different languages (English, German and French) is: * display Pokedex with numbers and localised names, * view types, required eggs, candies or legendary attribute, * record your CP and HP values, * display maximum and evolvable ranges of CP and HP both from and to your Pokemon (i.e. reverse and not). I kept everything as close to Casio's OS style as I could making navigation intuitive but a few key shortcuts worth mentioning: UP/DOWN - increases/decreases Pokemon value by 1 PLUS/MINUS - increases/decreases Pokemon value by 10 MULTIPLY/DIVIDE - increases/decreases Pokemon value by 100 DEL/UNDO - toggles between minimum (Pokemon shade view) and medium of the range value of your Pokemon Please leave your comments on or on any other relevant post here.
More Information PONG - Prizm C - Beginner's Example, now with comments! [[Screenshots] [9/10]]
I present to you, the laurels of about... maybe an hour of work... PONG! This version of PONG is for the Casio Prizm, very true to the original, and meeting the goals of development I planned for it: - under 50KB total for the entire Add-in - achieves over 15 FPS with decent video effects - entirely developed in under an hour - uses only routines available in the Useful Prizm Routines and libfxcg I did this as a proof that native development on the Prizm is very easy to do now, even without an abstraction layer like SDL. It also is meant for beginning C for the Prizm programmers to tear apart as a very easy game example, from which they can learn to make their own Add-ins. That being said, I also took my spare time to add in some small video noise effects to make it look cooler, and both an AI and 2 Player mode. Controls are: F1/F2 - menu choices Shift/Alpha - Player 1 Up/down Up/Down - Player 2 up/down Exit - exit to title screen Tear it apart and enjoy it! It's far from perfect, but it's still fun to play. If you do try to learn by improving upon it, and re-releasing it, give me some credit, s'il vous plait. And now, with comments!

More Information Pizm (pi learner) [[Screenshots]]
This little plug-in can display the first 15000 digits (following the decimal point) of π (number pi). You can use it just for fun but this program can also help you by learning the digits. Currently 15000 digits are stored but if you need more (I can't imagine why...) just write me and I will add more digits. It's important that digits are stored and not computed, future releases might include this feature. Source available under GPLv3 at:
