Also fixes presets/clear buttons for NTT, Pachinko & Hypershot, and improves layout for all controller config popups (buttons/borders are aligned, etc.)
-The pachinko/subor mouse/ntt/virtual boy controllers could be selected in the UI for 2p/4p adapters, but did not work at all
-Keybindings for the "custom keys" for some controllers were not working when connected to a 2p/4p adapter
-Pachinko controller did not allow the user to configure the keybindings for NES-style buttons
The Pocket Challenge V2 is an education handheld based on the ASWAN SoC, as used in the WonderSwan. It uses the same boot ROM (with an early exit), but has some implementation changes:
The LCD icon segment area is not present (on the display panel only).
There is no onboard internal EEPROM.
The input keypad layout differs.
The headphone output is always used with a custom onboard DAC, as opposed to relying on the SoC's own PWM DAC for the internal speaker.
This PR implements support for all of this. Support for the PCv2-exclusive cartridge mapper (KARNAK) will be added by a separate PR.
