Use4All2 Mod is an Amiga emulator for Vita. 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.

Features

• Full speed emulation of most Amiga games with zero frameskip
• Large, complete virtual keyboard with adjustable position and adjustable transparency
• Six fully mappable custom control sets: map Vita/Switch buttons to any Amiga joystick or key input
• Multiple hard-file support: up to 4 hdf files (size <2GB each on Vita, size <4GB each on Switch) can be mounted simultaneously
• Multiple controller support on Vita TV/Switch: up to four (eight on Switch) paired controllers can be fully mapped
• Analog mouse control: control the mouse using the analog stick with adjustable sensitivity
• Shader support: default "sharp_bilinear_simple" uses integer pre-scale for sharp, undistorted pixels with minimum blur, even if game is zoomed to fill the full screen
• Custom autofire: any mapped Vita/Switch button can have autofire with adjustable rate
• Savestate with hard-file support: state can be saved even when hard-files are used
• Additional emulator settings: sprite-sprite collisions can be enabled, blitter settings can be changed
• Adjustable stereo separation
• A button can be mapped to "slow mouse" in custom controls. When custom controls are on and that button is held down, the mouse pointer speed is greatly reduced. This is useful for precisely positioning the cursor.
• Sticky virtual keyboard modifiers: allows keyboard combos like CTRL-C to be entered easily
• Touchpad style pointer controls using the touchscreen
• Parallel port joystick adapter support for multiplayer games with up to 4 joysticks.
• Additional savestate slot called auto, for automatic savestate loading
• Physical keyboard and mouse support (Bluetooth on Vita, USB on Switch)
• Supports loading files from ux0: or uma0: partition (Vita only)
• Rear touch panel can be enabled for mouse pointer control (Vita only)
• Split Joy-Con support (Switch only)
• A "fast mouse" custom button can be mapped to speed up the mouse
• Automatic full 1080p support in docked mode (Switch only)
• Savestate import/export to backup savestates
• Config file management (load, save as, etc.)
• Thumbnail previews for savestates
• Four different on-screen keyboard styles: original, warm, cool, and dark
• On-screen keyboard keys can be pressed via touch input in addition to dpad navigation

Installation

• 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.

You can purchase legal bios roms from Amiga Forever. They work. But since they are encrypted, you have to copy over your .key file along with the roms.

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 ...
