3ME

3ME is an attempt to emulate Sorry, Marvin! in one instruction by Unname4798.

Implementation

var reg = [0,0,0,0];
var progp = 0;
var regp = 0;
var MMME = function (prog) {
 while (true) {
  if (prog[progp] >= 0) {
   regp = regp + 1 % reg.length;
   reg[regp] += prog[progp];
   progp++;
  } else {
   if (reg[regp] > 0) {
    reg[regp]--;
    progp++;
   } else {
    progp = progp + abs(prog[progp]) % prog.length;
   }
  }
 return reg;
 }
}
