So we are talking pie-in-the-sky. Anyone can do anything, given enough time and money and effort, but no one is going to do it, so what is the point? Just asking.
The point is that as I just discovered, the Creative chip is an all-in-one solution with DSP, DAC and ADC and the board uses a short signal path and a known good Burr-Brown op-amp, high quality Japanese Nichicon audio capacitors in an isolated section on the board and a discrete filtered power supply.
In addition to this, Aces High among many other games is not on the supported Alchemy games list, indicating that it probably runs in software, not hardware accelerated mode.
So technically, what makes it so bad? Prejudice.
Call me crazy but to me that looks like as far as technology and components go, the board does not get ashamed at all by a discrete Creative card (especially one that uses also a Core3D chip).
