I looked those up and they don't seem to match Yellow heart's look. So could it be possible she is a fake CPU?
Then there is that other theory that she is Compa as a CPU in this alternate dimension.
Well they don't have to match 100%. Just look at Neptune. Neither the 32x nor the proposed Neptune systems were colored purple.
I thought about those 2 while looking at Yellow Heart for these reasons:
~Hair - The 3DO was developed in the West, so they made her a blondie. Could also possibly be connected to the Bee mascot of Hudson Soft (who worked in tandem with NEC for the PC Engine) whose color matches the hair as well.
~Body type - The early Japanese PC Engine had a white model (same with the PCE Duo and Duo RX), and some of the bigger specs of any home console during it's heyday. No body feature matches for 3DO, but it also has the "bold specs but lack of support and prohibitive pricing" clause.
The PC Engine seems closer though, since it was intended as a Famicom competitor. White Heart's look in V is that of the Japanese Famicom.
The reason why you probably didn't see the connection is because you might have just looked at the Turbo-Grafx 16 import model, which was black since day one.
Since this is a Japan-made game, you have to look at the console platforms from their side of the fence.
