array sizes in GPU

[saku-koodari]

Code snippet GPU's constructor:

        public GPU()
        {
            _logWriter = new LogWriter(typeof(GPU));

            // NOTE: if you use 3D array instead of jagged one, you could do this:
            // _tilemap = new byte[0x200, 0x8, 0x8];
            _tilemap = new byte[0x200][][];
            for (var i = 0; i < 0x200; i++)
            {
                _tilemap[i] = new byte[0x8][];
                for (var j = 0; j < 0x8; j++)
                {
                    _tilemap[i][j] = new byte[0x8];
                }
            }

            _vram = new int[0x2000]; //8192
            _oam = new byte[SCREEN_WIDTH];
            _reg = new int[1];
            throw new NotImplementedException("// TODO: find out what is the size of the _reg");
            _scanrow = new byte[SCREEN_WIDTH];
            _palette = new Palette(COLORS_IN_PALETTE);
            _objectData = new ObjectData[40];
            // TODO: you also might remove every hardcoded values from here.
            throw new NotImplementedException("// TODO: find out where ObjectData's size (40) comes from.");
            _screen = new Screen(SCREEN_WIDTH, SCREEN_HEIGHT, COLORS_IN_PALETTE); // TODO: maybe you can use this instead of constants?
        }
