Yes, for nostalgia and historical curiosity.
A handful of titles (Tower Bloxx, Bejeweled 2, Block Breaker 2) are genuinely well-adapted to resistive touch. However, most 240x400 touch games are inferior to their keypad versions because developers treated touch as an afterthought.

But if you have a functioning 240x400 touchscreen phone or an emulator, exploring these .jar games offers a fascinating snapshot of pre-iPhone mobile gaming’s final years.
Would you like a specific list of working .jar files with download links, or guidance on configuring J2ME Loader for 240x400 touch emulation?
The year was 2009, and the world was caught in a strange, pixelated transition. The era of the clicking keypad was dying, but the sleek glass of the modern smartphone hadn’t quite taken over. In this middle ground lived the Samsung Star GT-S5230 , a "touchscreen for the masses" with a unique screen resolution.
For Leo, a teenager in a small town, that screen wasn't just a display; it was a window into a universe that fit in his pocket. But there was a problem. Most mobile games were made for the standard 240x320 "portrait" screens. On his Star, they looked tiny, squashed, or left a massive, ugly empty space at the bottom.
To fix this, Leo became a digital hunter, scouring the depths of the internet for the rarest treasure: the file optimized for 240x400. 🕹️ The Hunt for the Perfect JAR
The journey usually started on a slow home PC, searching through forums like . Finding a game was easy; finding the right version was the challenge. The Mismatch:
A 240x320 game would run, but the touch controls were often "ghosted"—you'd tap the screen, but the game thought your finger was two inches higher. The Adaptation:
Leo learned the magic of "Touchscreen Classic" and "Touchscreen 3x5". The Transfer:
He’d drag the file via a tangled USB cable or a tiny MicroSD card. 📱 A Catalog of Memories
When he finally hit the "Install" button on a properly formatted game, the screen came alive. Because 240x400 was wider (or taller) than the norm, the games felt cinematic.

. The 3D graphics were jagged and the frame rate chugged, but as he navigated a mutant-filled lab as Agent Ivan Molotov, the 240x400 screen made him feel like he was holding a top-secret military device. 🏛️ The Legacy
Eventually, the Java era ended. Android and iOS brought "apps" that didn't need hunting. But the 240x400 .jar files remain frozen in time—tiny capsules of a world where "Full Touch" was a brand new promise. Today, enthusiasts still keep these games alive using J2ME-Loader

In the late 2000s, there was a specific magic to the 240x400 screen resolution—the hallmark of high-end feature phones like the Samsung Star, LG Cookie, and various Corby models. This is a story about a single .jar file that defined a summer. The Quest for the .JAR
The year is 2010. You’re sitting in the back of a classroom, shielded by a stack of textbooks. In your hand is a sleek, resistive touchscreen phone. It doesn't have an app store; it has a file manager. You’ve spent the previous night browsing forums like 4PDA and mobile fan sites, hunting for the "Full Touch" version of a new release.
Most Java games are made for D-pads (240x320), but you need that extra height. You finally find it: a 240x400 .jar file. You transfer it via Bluetooth—a slow, agonizing progress bar that feels like a digital handshake between friends. The Loading Bar of Destiny
You tap the icon. The screen rotates. For a moment, the "Java" coffee cup logo appears, and then the developer splash screen—maybe it’s Gameloft, Net Lizard , or Digital Chocolate. The game is a tactical shooter or perhaps a simulation like Farm Frenzy
. Because it’s optimized for 240x400, there are no ugly virtual buttons blocking the view. The icons are crisp, and the touchscreen—while needing a firm press of a fingernail or a stylus—responds with a satisfying mechanical feel.

Every vibration of the phone is a heartbeat. You ignore the low battery warning, dimming the brightness to squeeze out ten more minutes of gameplay. The 240x400 canvas is your window into a world of pixelated glory, where "multitasking" meant closing one game to open another. The Legacy
Eventually, the bell rings. You slide the phone into your pocket, the screen still warm. That .jar file stays on your memory card for years, a tiny capsule of 300KB that held an entire universe. It wasn't just a game; it was the peak of the "Feature Phone" era, a bridge between the clicky buttons of the past and the glass slabs of the future.

Game Development Tips
Example Code
Here's a simple example of a Java ME game that uses touchscreen events:
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class TouchGame extends MIDlet
private Display display;
private Canvas canvas;
public TouchGame()
display = Display.getDisplay(this);
canvas = new TouchCanvas();
display.setCurrent(canvas);
protected void startApp() throws MIDletStateChangeException
// Initialize game state
protected void pauseApp()
// Pause game state
protected void destroyApp(boolean unconditional) throws MIDletStateChangeException
// Clean up resources
private class TouchCanvas extends Canvas
protected void paint(Graphics g)
// Draw game graphics
public void pointerPressed(int x, int y)
// Handle tap event
public void pointerDragged(int x, int y)
// Handle drag event

Common toolchain: NetBeans/IDEA + Sun Java Wireless Toolkit or manufacturer SDKs; device emulators for testing. Asset pipelines included Photoshop/GIMP and custom texture packers. Distribution was typically via carrier portals, third‑party stores, or direct downloads—.jar and .jad bundles were the norm.
Practical tips:
Not every game translated well to touch. Action games requiring rapid "button mashing" were terrible on resistive screens (you had to press hard). However, several genres thrived:
In the mid‑2000s the mobile world split into two overlapping eras: feature phones with Java ME (J2ME) and the earliest touchscreen handsets. Screen sizes varied wildly; 240×400 pixels (a tall QVGA variant) became common on lower‑end touchscreen models. Developers adapted the familiar .jar/.jad Java packaging to these new input methods. What began as joystick- and keypad‑centric design evolved quickly to accommodate taps, drags, and multi‑touch workarounds.
| Aspect | Details | |--------|---------| | Control | Virtual buttons drawn on screen, or direct tap on objects. No physical keypad needed. | | Performance | Often slower than keypad versions; framerate 15–25 FPS typical. | | Graphics | 16-bit or 18-bit color; parallax backgrounds rare; pre-rendered 2D sprites. | | Sound | MIDI or low-bitrate PCM; music often absent to save heap memory (typically 2–4 MB). | | Save system | Usually via RMS (Record Management System) – 1–3 save slots. |
