Adds the following features over previous release:
Save and load snapshots
Save the emulator state to SD Card at any point . On reloading a snapshot the emulator will continue from exactly where the snapshot was saved. No need to restart from the beginning after you die in a game! Also save a snapshot to avoid re-running lengthy set-up times in programs. A snapshot saved on one machine can be loaded on another, even with a different sound or display set-up. Full details are given in the Readme
Change resolution on program load
It is now possible to specify the display resolution for a program. If the current resolution is different then the emulator restarts in the correct resolution before the program is loaded
Support for Raspberry PI Pico SDK 2.1.0
This release was built with SDK 2.1. Issues in SDK 2.1 resulted in the develop branch being used, plus the TinyUSB submodule from SDK 2.0
Olimex 9 Pin Joystick Support
It is now possible to add a 9 pin joystick adapter to the Olimex RP2040-PICO-PC board, via the UEXT1 connector
