PSP UAE4ALL is an Amiga emulator for the Sony PSP based on Chui's Dreamcast UAE4ALL and notaz's UAE4ALL GP2X.

Features

  • Specific features:
    • Based on latest Chui’s Dreamcast UAE4ALL and notaz’s uae4all gp2x v0.7.2a optimized blitter routines.
    • Maximum speedup hacks using single precision math hardware support.
    • Full screen hardware scaled support.
    • Fixed Overclock to 333 MHz while emulating, 222 MHz in menu.
    • Only 546KB kernel build version (1.7MB user mode build).
  • Same features as Dreamcast version:
    • Frameskip between 0-1 without sound and 1-2 with sound.
    • Fast FAME Motorola 68000 C core by Fox68k.
    • Autoframeskip for real speed.
    • Mouse support.
    • Joystick support.
    • Fast sound with 8 buffers synchronized.
    • Filemanager with subdirectories access.
    • Complete menu with load, throttle, frameskip, reset… options
    • Save disks changes into Virtual memory files (testing).
    • Superthrottle mode for speed up intros and loading time.
    • ADZ support (ADF floppy image gzip compressed)
    • 2 floopy drives emulated.

Installation

There are two different builds in archive:

  • psp_uae4all_r1 - 1.50 Kernel mode.
  • psp_uae4all_r1-usermode - 2.00 User mode

Use psp_uae4all_r1 as installation base, then replace EBOOT.PBP if you have slim PSP or would use user mode build (ms0:/PSP/GAME/).

Copy kickstart file named kick.rom of version 1.3 (edited 2008-01-17:512k overdump version) in same folder.

Copy disks images as .adf or .adf.gz (.adz) compressed format into disks folder, for convenience.

User guide

SuperThrottle:

  • Hold right trigger first and left trigger second for automatic sound off and frameskip to 10 for speed up.
  • This try to avoid large time for intros and loading time.

ADZ support:

  • You can compress your ADF floppy images with GZIP compression utility in order to save CD space.
  • GZIP is free and multiplatform: Windows, GNU/Linux, MacOS … better use short filenames to read correctly disks numbers.

Save disks changes to VM:

  • UAE4ALL can save to VM disk sectors changed using ZIP compression.
  • For games as Dune2, now you can save your campaigns and continue at future.
  • A new menu option called “Save Disks” has added for enable or disable this feature.

2 floppy drives emulted:

  • You can choose on filemanager a new disk for DF0 with Cross button and a new disk for DF1 with Square button.
  • Also, you can eject DF1 with 'Eject DF1' option or pressing Triangle button while in menu.

Throttle:

  • Amiga is a hard machine to emulate. So, a lot of games support drawing shortcuts and cpu timeslice ampler.
  • These methods speed up emulation and improve playbility under PSP.

Autoframeskip:

  • Unfortunately, UAE4ALL needs frameskipping for real time emulation. Active auto-frameskip menu option for real speed.
  • If you want sound, it’s a very important thing, the sound needs to be synchronous.

Mouse:

  • Some on loading game demo requires specific mouse buttons combo, so try both buttons and movements while in such menu’s or demo.
