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.
