Script wrapper allowing most bustadice (promise based API) scripts to be used on bustabit (event based API). Reason why I say most scripts is because there are a few differences which have no equivalent like seed change functions.

bustadice-wrapper-v1.js

var config = {
    baseBet: { type: 'balance', label: 'Base Bet', value: 100 },
    payout: { type: 'multiplier', label: 'Payout', value: 2 },
    maxBet: { type: 'balance', label: 'Max Bet', value: 100000 }
};

// Note: if the bustadice script contains a config or options like above,
// then it will need to be separated and placed at the very top still and
// the rest of the script is placed in the designated area below.

class Script {
    constructor(context){
        this.context = context;
        this.log = log;
        this.stop = stop;
        this.skip = async function(){
            return new Promise((r) => {
                context.once('GAME_ENDED', () => { r({context.history.first().bust, this.balance}); });
            });
        }
        this.bet = async function(value, target){
            return new Promise((r) => {
                context.once('GAME_STARTING', ()=>{ context.bet(value, target); });
                context.once('GAME_ENDED', ()=>{ r({value, target, context.history.first().bust, this.balance}); });

            let currentBet = config.baseBet.value;
            for(;;){
                this.log(`Next bet ${Math.round(currentBet/100)} bits.`);
                const result = await this.bet(Math.round(currentBet/100)*100, config.payout.value);
                if(result.multiplier < result.target){
                    this.log(`We lost ${currentBet/100} bits.`);
                	currentBet *= (config.payout.value/(config.payout.value-1));
                }else{
                    this.log(`We won ${(currentBet*(config.payout.value-1))/100} bits profit.`);
               	currentBet = config.baseBet.value;
    	        }
                if(currentBet >= config.maxBet.value){
