[saku-koodari]

Code snippet from Memory.cs WriteByte - method, around line 245-250:

                        // OAM
                        else if (bAddress == 0xE)
                        {
                            // if((addr&0xFF)<0xA0) GPU._oam[addr&0xFF] = val;
                            // GPU.updateoam(addr, val);
                            throw new NotImplementedException("TODO: GPU");
                        }
                        // Zero-page RAM, I/O
                        else if (bAddress == 0xF)
                        {
                            if (address > 0xFF7F)
                            {
                                _zram[address & 0x7F] = value;
                            }
                            else
                            {
                                switch (address & 0xF0)
                                {
                                    // I Wonder why this is here...
                                }

                                _logWriter.WarnFormat(warnMessage, "Zero-page RAM, I/O");
                            }
                        }

There is a longer snippet because there are empty switch case. Also Find out why it's there.
