It is widely known that opossums have the instinct to repel aliens. You can now practice your opossum massaging skills on the TI-84 Plus C Silver Edition, TI-84 Plus CE and HP Prime calculators! There are three CE versions, sort-of: One of which uses Celtic CE but runs slower, an older one using ICE Compiler which no longer works with newer C library versions, a Game Boy ROM converted to appvar for use in TI-Boy CE emulator and the ROM file itself for use in a PC Game Boy emulator or on original hardware. The Game Boy version is included for use in TI-Boy CE because it runs smoother despite being emulated.

Supersonic Ball HP is an HP Prime remake of my TI-83 Plus and TI-84 Plus Axe Parser platformer. It features parallax animated backgrounds and sprites like the original and was written in HP PPL. For speed reasons a G2 model is recommended but since version 0.30 beta the gameplay speed has increased dramatically and there are now 4 extra level types that weren't in the original 83+ version. Version 1.01 fixes the high score resetting itself to zero every time the game's code is opened by accident.

The program eqnlib offers 47 equations for HP Prime’s Solver App. Just run the eqlib program, select the category that you are interested in, and select the equation within that category and you are off and running!
The equation selected will be loaded into the system variable E1. The program will show you what each variable represents in the solver. Keep this screen up as long as you like. When done, press [Enter], and you will be taken to the Numeric View of the Solve App. To see the equation, press the soft (Defn) key.

JezzBall is an arcade-style game for the HP Prime, written primarily in Python with a few snippets of PPL code.
The objective is to fill at least 75% of the rectangular playfield by launching splitters that divide the space. Balls bounce around the area, and if a splitter comes into contact with a ball while it's extending, the splitter is destroyed and you lose a life. When a splitter successfully divides the area into two parts, the region without any balls gets filled, bringing you closer to your goal. With each new level, splitters get faster and more balls appear on the playfield—steadily raising the challenge and testing your timing and precision.

This is the official release of my HP Prime port of my HP 39gII Tunnel clone written in BASIC, now adapted for the larger screen and color display. This new version adds speed throttling to ensure that the game runs as close as possible to the same speed as the original HP Prime on both the emulator and G2 hardware revision of the calculator. It is probably the first ever game ever made available for download for this calculator model. It isn't meant to show coding skills, especially considering the game was made before my knowledge of the DIMGROB_P and BLIT_P commands (although an intro transition using them was added afterward), but as you'll see on-calc, even if I have to refresh the entire screen content every frame, I still get insane FPS. Because of how incredibly fast this calc is, this is why I manage to get such high framerate even with redrawing the entire screen rectangles and score text every frame. As for the multicolor and 3D-ish text effects, they are possible because the HP Prime lets you use text with no background, so all you have to do is superpose multiple copies of that text, gradually changing its color and position through a FOR loop. This also lets you use bold text. To play, just use the UP and DOWN keys and quit with ON. Here is a Youtube video by Critor of it running on a real calc, but the text color is different and it runs a little slower, since it's an older version: http://www.youtube.com/watch?&v=0WEjguctKNY

This is an app that implements a quasi-Newton solver (Newton-Raphson algorithm with backtracking linesearch). The app comes with a collection of systems of equations as found in the Equation Library on the HP48G series (and on the HP Solve application card for the HP48SX). Users may also create their own systems and save them for later use by adding on to the current library.

and Andre Schoorl. Their implementation is actually an adaptation
of Qpirac by A. Coulomb and the rationalize command from MuPad.
QPI basically takes a real number r and will return the real number as one of the following forms: p/q, (a/b)*√(p/q), (p/q)*π, ln(p/q), or e^(p/q).

Lambda supports a dictionary of lambda calculus expressions and the evaluation (application) of one term to another. It recognizes Church Numerals automatically, so these don't have to be added to the dictionary. This version uses standard notation Lambda abstractions and builds De Brujin for use in applications, avoiding alpha conversion needs. This app is based on HP's Spreadsheet app and uses the spreadsheet as a dictionary of terms. You can enter standard notation or De Brujin notation when adding terms and the app will calculate the other.

N = number of bolts
D = diameter of the circleNo angle of rotation is assumed.
The OC-Distance between each bolt is calculated by calculating
the linear distance between neighboring bolts.Output:

A highly optimized implementation of the classic Python turtle module for the HP Prime MicroPython environment. It aims to preserve a high degree of compatibility with the CPython Turtle API, making existing turtle-style code easier to adapt and run on the calculator. Internally, it uses a custom rendering pipeline with aggressive optimizations for drawing, filling, text rendering, and screen updates to achieve efficient and responsive graphics on HP Prime hardware.

IEEE754 converter v3
Today, the most prevalent representation of real numbers on computers is IEEE Standard 754 floating point.
This function converts floats to hexadecimal or vice versa using the IEEE-754 standard introduced in SSE instructions set.Syntax:
IEEE754(a, b)
"a" can be a decimal, hexadecimal or a string.
Hexadecimals are case-sensitive and must be uppercase.
Strings must be used to convert decimals with more than 12 digits.
In CAS mode strings must be used when convert from hexadecimals to floats e.g. IEEE754 ("#123h",16).
In CAS mode when convert from floats to hexadecimals, the result will be a string."b" can only be :
0 - Display this help
8, 16, 32 or 64 - bits base conversion
If bases are negative the result will show a string with more digits.Examples:
IEEE754 (3.14159265359, 64) → #400921FB54442EEAh;
IEEE754 (#400921FB54442EEAh, 64) → 3.14159265359;
IEEE754 ("3.141592653589793", 64) → #400921FB54442D18h;
IEEE754 (#400921FB54442D18h, -64) → "3.14159265358979311599796346854"In CAS mode:
IEEE754 ("#6Dh",8) → 14.5
IEEE754 (14.5, 8) → "#6Dh"If you find any error, please report to joaocaminha968@gmail.com

DwPrime v1 has been available since 2024, offering basic bitmap drawing features for the HP Prime.
This version 2 significantly extends that foundation with a broader toolset and refined workflow.
Drawing tools now include point, line, rectangle, circle, ellipse, polyline, eraser, and brush stamping.
Filled shapes, shading, and inverted-fill variants are available for rectangles, circles, and ellipses.
A dedicated selection tool supports copy, stamp, rotate, scale, mirror, move, and invert operations.
Text can be placed with or without a background, and a circular color picker handles palette selection.
Brushes are fully customizable and stored as compact RLE data, with binary and alpha (0-255) modes.
Transparency is handled consistently across drawing, fills, and selection operations.
Undo/redo is snapshot-based with a five-step history, cleared on exit to conserve storage.
The canvas supports zoom, a minimap, and two-finger touch panning for navigating larger images.
A file manager lists and paginates saved images, remembering the last-opened file automatically.
The interface is localized in English, French, German, Spanish, Dutch and Portuguese.
A built-in tutorial and help screen are available directly on the calculator.
The app is written in MicroPython and optimized for the Prime's memory and performance constraints.
Important note for the DwPrime Python application: You must set the following parameters to their maximum values: heap: 16384 - stack: 640000
Feedback and bug reports are welcome as development continues.
Happy drawing!
