Im sorry to tell you this, but on description of the book it sayes that code is entended to work on mobile phone, that is not reliable cos of timings and stuff. No computer gonna help you if you don’t understand what its entended to do. Computer is only usefull as timing calculator, rest of work you will be required to do by yourself. If you cannot do it by yourself without a comp, no comp gonna help you. Save yourself some time and lern vb. Then, if you can code, you can do comp by yourself or use Forester one ( its a good one that works). Im not attack you, just trying to help. I wasted lots of time with working device, but without understanding of what is required from player. Make a home work, then, if you want, buy Forester comp, or use no comp at all.
