    <h1>PICO-8 to TIC-80 cartridge converter</h1>
    <div id="jserr">Please enable JavaScript</div>
    <script>document.getElementById("jserr").style.display = "none";</script>
    <p>This is a <i>Free and Open Source</i> tool, licensed under the <i>MIT license</i> and written in ANSI C. It's aching to be
    feature complete, therefore it is able to convert assets, PICO-8 codepage, most of the <b>Lua syntax</b> (like <tt>+=</tt> and
    <tt>!=</tt> operators for example) and <b>API calls</b> too (what's not converted directly, provided via
    <a href="https://github.com/musurca/pico2tic" target="new">musurca's wrapper</a> library).
    Check out the converter's <a href="https://gitlab.com/bztsrc/p8totic">source</a>.
    Contributions and improvements are always welcome!</p>
    <input type="file" id="input" onchange="getfile()"><br>
    <small>If the input is a <samp>.p8</samp> text file or a <samp>.p8.png</samp> binary file or a <samp>.tic.png</samp>, then the output is a <samp>.tic</samp> file.<br>
    If the input is a <samp>.tic</samp> file, then the output is <samp>.tic.png</samp> cartridge.</small>
