Uae4All2 Mod for Vita v2.10 and Switch v2.12

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)

• fix regression causing stuttery audio after suspend by linking with fixed SDL2

2.11 (Switch only)

• fix touch input on Switch

2.10

• allow autostarting of config file via command line argument. On Switch, the same forwarder that works with RetroArch can be used. On Vita, a custom bubble builder is provided. It uses the same method as DaedalusX.

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.

• MD5 of verified working kickstart rom files, you can test yours at onlinemd5:

kick12.rom (256 kB): (MD5) 85AD74194E87C08904327DE1A9443B7A

• 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.

Vita/Switch-exclusive 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

• 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)

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.

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.

• MD5 of verified working kickstart rom files, you can test yours at onlinemd5:

kick12.rom (256 kB): (MD5) 85AD74194E87C08904327DE1A9443B7A
kick13.rom (256 kB): (MD5) 82A21C1890CAE844B3DF741F2762D48D

Uae4All2 mod for Vita and Switch v1.95

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.

Recent Changes

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.
