New Reuben Quest Game Released
Published by PT_ on January 6, 2017 at 3:37:45 PM CST | Discuss this article (9)

In what may be the oldest TI-Calc game series, Sorunome has released the latest installment to Reuben Quest for the monochrome calcs: Reuben Quest: Lost Between Times. The roots of the Reuben Quest series came from DJ Omnimaga who made Reuben Quest: Ev Awakening1 back in 2004 in pure BASIC, with the help of ASM libraries, which was also the second grayscale game for the TI-83 Plus/TI-84 Plus series (after tr1p1ea's Desolate) and the first grayscale JRPG for that calculator family.

In January 2005, DJ Omnimaga released a new Reuben Quest game, Reuben Quest: The Lost Mirror. This game added a lot of of puzzle-solving elements and much more, compared to Ev Awakening. We now finally have the latest installment, Reuben Quest: Lost Between Times. The game is "an epic RPG fantasy which includes tons of puzzles, side-quests, hidden things and much more!". The game is made in pure ASM, and has great greyscale which leads to gorgeous graphics, animations, fights, maps and much more. You should definitely give it a try, and challenge yourself to discover what - and where! - all the "hidden things" are!

Oiram (Mario) for TI-84 Plus CE Released
Published by PT_ on January 5, 2017 at 5:46:25 PM CST | Discuss this article (5)

In the middle of September 2016, Cemetech ASM expert and moderator MateoConLechuga decided to port the popular Nintendo game Mario to the TI-84 Plus CE. He started this game in ASM, but soon moved to C, using the libraries he wrote himself. Upon switching to C, he also renamed the game from Mario to "Oiram" ("Mario" reversed) to avoid problems with copyright infringement. After much nagging and poking from an impatient userbase and a few months of updates and gorgeous screenshots, he has now released Oiram! The game includes everything you'd expect from the original game: full movement, side-scrolling, goombas, turtles, fire sprites, shells and much, much more which makes this game into one of the biggest games released so far for the TI-84 Plus CE.

But that's not all! Like the real Mario game, Oiram includes time, coins, powerups and a score system. Mateo has created 12 levels, full of enemies, powerups, koopas, slopes (!), pipes and... hidden things! If you're sufficiently dedicated that you happen to beat all of the levels, you can keep the game interesting by making your own levels. Mateo has created a simple but useful Oiram Level Editor, which provides a GUI where you can make your own levels, and export them all together to an appvar. Simply send this appvar to your calculator, and then you can play your own levels.

If even this was not enough, Mateo has made the game open source, so if you want to learn how to write a platformer game, take a look!

Now that the polls to vote for your favorite program of the year are closed, ticalc.org has published the results of the 2016 Program of the Year contest. There were 4 categories, the TI-83 Plus/TI-84 Plus category, the TI-84 Plus C Silver Edition category, the TI-84 Plus CE category and last but not least the TI-Nspire category. There were numerous entries, but only one can win, so let's see who the winners are.

In the TI-83 Plus/TI-84 Plus category JWinslow23's This Is The Only Level has won the PotY by default, as it was the only program or game made for the monochrome calcs.

KermMartian had a resounding lead in TI-84 Plus C Silver Edition category with his program "Graph3DC". Other entries were

The TI-84 Plus CE category was the most interesting poll in my opinion, because there were 12 entries competing with each other. Cemetech global moderator PT_ won this category with his program "ICE Compiler". Other programs/games that were in the running were:

The last category was the TI-Nspire category, and this poll was won by Jens Kolbinger with his program "Jens' Script Editor". The other programs or games to vote at were:

Congratulations to all winners, thanks everyone for voting, and if you didn't won, don't be sad, at least your program was frontpaged!
