About

This is a fork/variation of the excellent db48x simulator written by Christophe de Dinechin for the SwissMicro DM42 calculator. This code is a proof-of-concept, is provided as-is, and is likely out of date. As such, this code is not supported by Christophe — please refer to the original repository.

WASM simulator

The simulator implementation of db48x utilises Qt which runs fairly sluggishly on low resource devices such as handhelds. The motivation is to port the simulator from Qt to something more portable such as WASM which can run on mobile devices.

A very basic simulator is wired up to a WASM compiled binary of db48x, which then runs on HTML and Javascript for use on mobile devices. Be warned that there are many bugs, with the simulator hanging when accessing system services (help, save state, system menu) which are not implemented .

Building the simulator

Install and activate emsdk then ensure that it is available in the path. Run make within this repo to build main.js and main.wasm. Host the files within the bin directory via a webserver.

Running the simulator

Point your web-browser to the index.html page to run the simiulator. The simulator can be run fullscreen by selecting "Add to Home Screen" on iOS or your Android device.
