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.
Thanks to Cpasjuste for the original port and for jumping in and adding shader support and making the assembler optimizations work.
Thanks to ScHlAuChi for extensive testing, ideas, and for contributing the new larger virtual keyboard images.
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, Matthew Machnee, and Sean Ritzo.
INSTALLATION
Obtain and copy BIOS files kick13.rom (size: 262,144 bytes), kick20.rom (size: 524,288 bytes) and kick31.rom (size: 524,288 bytes) to your SDCard into /switch/uae4all2/kickstarts/
Use your favorite Homebrew Launcher or Homebrew Loader to start Uaeall2
Full speed emulation of most Amiga games with zero frameskip
Large, complete virtual keyboard with adjustable position and adjustable transparency
Three fully mappable custom control sets: map Vita buttons to any Amiga joystick or key input, three custom control sets supported
Multiple hard-file support: up to 4 hdf files (size <2GB each) can be mounted simultaneously
Multiple controller support on Vita TV: up to four 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 Vita screen
Custom autofire: any mapped Vita 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.
Bluetooth keyboard and mouse support
Sticky virtual keyboard modifiers: allows keyboard combos like CTRL-C to be entered easily
Touchpad style pointer controls using the front touch panel and (optional) the rear touch panel
Supports loading files from ux0: or uma0: partition
Parallel port joystick adapter support for multiplayer games with up to 4 joysticks.
Additional savestate slot called auto, for automatic savestate loading
