  • 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.
