PPSSPP barely runs (if at all) on Samsung GT-S5300

[Livy.]

Specs: Samsung Galaxy Pocket (GT-S5300)

• CPU: ARMv6
• GPU: Unknown
• RAM: 256 MiB
• OS: Android 2.3.6
  

First of all, I have reset the device to factory default to prevent other programs to interfere.

PPSSPP does run, but most of the time, after an ISO or ELF is selected, the whole system freezes. At the time of freezing, no game graphics is shown, just a black screen with virtual buttons. It forces me to hold the power button to turn off the phone.

In some rare cases, the game or elf runs, but with broken graphics. The cube test for example: a part of the cube is render at the middle of the screen, while other parts are at many locations of the screen. I think if they are brought together, it will be a full cube. It happens with both the cube.elf and Ridge Racer 2, the only game I have at the moment.

There is a funny thing, though. If PPSSPP successfully boot an elf or iso, then it will successfully boot without freezing the whole system... until the phone restarts. After a system restart, the result is unpredictable. I thought it was due to RAM shortage, but it wasn't. Normally the RAM usage is ~180 MiB when the system boots up. I used Task Manager to free RAM (to 150 MiB) before running PPSSPP, but it still freezed my phone.
