  • Fast sound with 8 buffers synchronized.
  • Filemanager with subdirectories access.

  • 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 (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.
