Important note to Switch users

On the Switch, since v1.84, please use Application mode, not Applet mode, to start uae4all2, otherwise the config save as and savestate export options will not work. You can do this by holding down R while launching any game to make hbmenu appear in Application mode. In other words: launch uae4all2 via game, NOT via Album.

Recent Changes

2.12 (Switch only)

In this mode, Vita buttons can be mapped to any Amiga side keyboard key or joystick action. There's also a mapping option called "slow mouse." It will slow down the mouse pointer by a factor ten if that mapped button is held down. Up to four controllers can be mapped (for multiplayer on VitaTV and Switch). Four Amiga-side joysticks are supported. Joystick 3 and 4 are on the emulated parallel port joystick adapter.

Virtual keyboard controls

Start = Toggle virtual keyboard
Right analog stick up/down = Move virtual keyboard up and down
Right analog stick left/right = Change virtual keyboard transparency
Cross = Press selected key (on Switch, this can be changed from B to A)
Square = Backspace
Triangle = Toggle shift
Circle = Turn off all sticky keys (ctrl, alt, amiga, and shift) (on Switch, this can be changed from A to B)

Touch controls

Note: for multi-touch gestures, the fingers have to be far enough apart from each other, so that the Vita will not erroneously recognize them as a single finger. Otherwise the pointer will jump around.

Single short tap ...

Important note to Switch users

On the Switch, since v1.84, please use nsp injection to start uae4all2, otherwise the config save as and savestate export options will not work. On SX OS, you can do this by holding down R while launching any installed game to make hbmenu appear.

Installation

Vita:
- Install .vpk
- Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to ux0:/data/uae4all/kickstarts.
- Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.
Switch:
- Download and unzip uae4all2_switch.zip
- Copy the resulting folder uae4all2 to /switch/ onto your SDCard, ensure none of the "archive" flags is set.
- You should now have the executable /switch/uae4all2/uae4all2.nro and a folder /switch/uae4all2/data/ with the keyboard icons and other data files on your SDCard.
- Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to your SDCard into /switch/uae4all2/kickstarts/.
- Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.

Controls

General

(For Switch: Cross = B, Square = Y, Triangle = X, Circle = A, Select = Minus, Start = Plus)

Select = Toggle menu
Start = Toggle virtual keyboard
R+Start+Dpad up/down = Move screen up/down
R+Start+Dpad left/right = Change screenmode (to zoom in on games with borders)
Right analog stick = Analog mouse (can switch this to left stick in menu)

When custom controls are off

Up to four controllers are automatically mapped to players 1-4. Players 3 and 4 are on the emulated parallel port 4 player adapter.

Left analog stick = Amiga joystick directions
Dpad = Amiga joystick directions
L shoulder button = right mouse click (player 1 only)
R shoulder button = left mouse click (player 1 only)
(Shown below are control presets 1 (default) / 2 / 3 / 4)
Square = Autofire (default) / Fire / Autofire / Fire
Cross = Fire (default) / Autofire / Up (Jump) / Up (Jump)
Triangle = Space (default) / Space / Fire / Autofire
Circle = Secondary Fire (used only in a few games)
R+Square = Ctrl
R+Circle = Left Alt
R+Cross = Help
L+Square = Left mouse
L+Circle = Right mouse
R+Dpad = Arrow keys

When custom controls are on

L+Start = Toggle between custom control set number 1, 2, 3, 4 and 5

In this mode, Vita buttons can be mapped to any Amiga side keyboard key or joystick action. There's also a mapping option called "slow mouse." It will slow down the mouse pointer by a factor ten if that mapped button is held down. Up to four controllers can be mapped (for multiplayer on VitaTV and Switch). Four Amiga-side joysticks are supported. Joystick 3 and 4 are on the emulated parallel port joystick adapter.

Virtual keyboard controls

Start = Toggle virtual keyboard
Right analog stick up/down = Move virtual keyboard up and down
Right analog stick left/right = Change virtual keyboard transparency
Cross = Press selected key (on Switch, this can be changed from B to A)
Square = Backspace
Triangle = Toggle shift
Circle = Turn off all sticky keys (ctrl, alt, amiga, and shift) (on Switch, this can be changed from A to B)

Touch controls

Note: for multi-touch gestures, the fingers have to be far enough apart from each other, so that the Vita will not erroneously recognize them as a single finger. Otherwise the pointer will jump around.

Single short tap = left mouse click
Single short tap while holding a second finger down = righ...

Important note to Switch users

On the Switch, since v1.84, please use nsp injection to start uae4all2, otherwise the config save as and savestate export options will not work. On SX OS, you can do this by holding down R while launching any installed game to make hbmenu appear.

Description

Use4All2 Mod is an Amiga emulator for Vita and Switch. This is my mod of this great Amiga emulator that was originally ported to the Vita by Cpasjuste. Depending on when you read this, this mod might be ahead or behind his version.

More Screenshots:

Thanks to Cpasjuste for the original port, for jumping in and adding shader support, for making the assembler optimizations work, and for fixing audio playback on suspend/resume in SDL2 for Switch.

Thanks to ScHlAuChi for extensive testing, ideas, and for contributing the new larger virtual keyboard images.

Thanks to wronghands for the new, better-looking menu font, all the new keyboard styles, and many ideas.

Thanks to CrashMidnick for the French virtual keyboard.

Thanks to the original authors Chui, john4p, TomB, notaz, Bernd Schneider, Toni Wilen, Pickle, smoku, AnotherGuest, Anonymous engineer, finkel, Lubomyr, pelya and many more.

Thanks to my supporters on Patreon: Andyways, CountDuckula, Greg Gibson, Jesse Harlin, Özgür Karter, Matthew Machnee, and RadicalR.

Installation

Vita:
- Install .vpk
- Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to ux0:/data/uae4all/kickstarts.
- Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.
Switch:
- Download and unzip uae4all2_switch.zip
- Copy the resulting folder uae4all2 to /switch/ onto your SDCard, ensure none of the "archive" flags is set.
- You should now have the executable /switch/uae4all2/uae4all2.nro and a folder /switch/uae4all2/data/ with the keyboard icons and other data files on your SDCard.
- Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to your SDCard into /switch/uae4all2/kickstarts/.
- Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.
- Use nsp injection to start uae4all2, otherwise the config save as and savestate export options will not work. On SX OS, you can do this by holding down R while launching any installed game to make hbmenu appear.

Switch controls

The default OK button in menu and on-screen keyboard is B. This can be changed to A in "more options."

ZR button = slow-mouse (if custom controls are off)
ZL button = fast-mouse (if custom controls are off)

Split Joycon Mode: Split Joycon mode can be enabled/disabled in "more options." Upto four single Joycons are supported. Buttons can still be remapped. SL for player 1 is hardcoded to bring up the keyboard.

Split Joycon Controls:
Minus/Plus = Menu (player 1 only)
SL = on-screen keyboard (player 1 only)
Pressing stick while moving it = change keyboard transparency/position, control mouse pointer (player 1 only)
SR + SL + Stick directions = hotkey to quick-zoom image and center image vertically (player 1 only)

Physical Keyboard / Mouse controls

On Vita (Bluetooth): Mouse + keyboard tested working with the "Jelly Comb Mini Bluetooth Keyboard With Mouse Touchpad, ASIN:B06Y56BBYP," and with the "Jelly Comb Bluetooth Wireless Mouse ASIN:B075HBDWCF." The Amiga keys are mapped to Windows (GUI) keys as well as Page Up/Down. The Vita doesn't pair with all Bluetooth keyboards and mice. As a rule, if the keyboard works to highlight bubbles with cursor keys, it should also work in UAE4All.

On Switch (USB): All keyboards seem to work. Not all mice seem to work. A tested working mouse is the Logitech M187.
