Yes because canoe does not emulate the SDD-1.
You need uncompressed GFX Data Paks in order to have the correct GFX.
This way they do not need to divert power to any SDD-1 Emulation.
It was done on SNES9x the same way back in like 2005.
But back then it was not about the recources, it was becuase the compression was not 100% understand at this time.
Today there is proper SDD-1 emulation but that needs more power.
People always want what is hard or impossible to get...
In this case most get it to run at one point, play it for like 5-10 minutes and then they never look at it again.
