* DATEL: Make read sector function vram safe The platform code was performing reads in single byte units, breaking in case the destination buffer was in vram. This caused issues with some games (e.g. Castelvania Order of Ecclesia), and also broke soft resetting. * Halve wait timeout on sector read since we read 2 bytes at the time
