The GBP is literally a GBA stuck underneath a GC. That's why it doesn't have any SGB capability because the GBA never did that (would have been awesome if the GBA had the resolution to do that though). It basically just pipes A/V generated by the GBA hardware to buffers the GC periodically reads. In that regard, it's boring in that it doesn't do anything fancy, no super hidden tricks that only happen on the Player and nowhere else. The only thing I can think of is that like the original SGB, the video timing is slightly off, so a GBA and GBP would technically give different TAS runs or something like that. The GBP also has some pretty borders you can use during gameplay, a timer, and some games (Mario & Luigi: Super Star Saga) feature rumble. There is probably some amount of color correction going on as well. Other than that, it's much less interesting that the SGB or the SGB2 (you could technically link together two SNES, kinda like GC LAN).
I'm just interested in getting it to work for the sake of completeness. Even if it is boring, it's boring history that needs to be preserved. I still want to know how exactly the GBP transfers video and audio and how the GC handles that whole process. Additionally, I want to see some games emulated on the GBP that would have been impossible to play in real-life. For example, Kirby's Tilt 'n' Tumble, WarioWare: Twisted, and Yoshi: Topsy Turvy are all pretty much no good on the GBP (unless you want to hold up your GC and spin it around). The GBA video series were explicitly incompatible with the GBP as well (probably because the video quality sucked more than anything else
) The only way to get those games working on the GBP is through emulation, so where emulation exceeds the limitations of the original hardware is another point of my fascination.
Guess I'm rambling again...
