The devs here are awesome like that. They make the GCW Zero a great device, without it would just be a brick with buttons and a screen.
This is true, and don't take them for granted (like I may or may not have done before)
Anyway, I've put this in the google document as well, but this is what I have tested so far (all USA versions):
Driver - Works with:
Final Fantasy Tactics - Works with: HLE BIOS
Mega Man Legends 2 - Works with:
BIOS note: audio is very out of sync during cut-scenes
Metal Gear Solid - works with:
All of the above run at a good frame rate and with little to no issues other than minor audio problems, except for MML2 as mentioned above, which for some reason has an increasing long difference in the video and audio during the cut-scenes. I have only played enough of each to test, so when I play through them for real there may be more to report.
I have a whole bunch of games I will try eventually, but my SD is just too small
