Ah yes, SiN the classic Playstation game.

Does this refer to just when the games are relatively new, or do 30 year old secondhand cartridges also count?

I don't think it's mentioned anywhere outside of the manual but you can swap L and ZL or R and ZR to have Z/R on the same row.

I'm a fan of the grip texture, d-pad and stick, but the plastic they used for the buttons feels a bit cheap for my taste, especially on the Z buttons. Like someone said above the lack of virtual controller paks on the A3D is disappointing. (That may be more on Analogue, though.)
As more of a personal nitpick, never been huge on the logo they plaster on their controllers.
I do hope they release some more face plates, the gold one they had as a stretch goal on Kickstarter seems like it would look nice with the purple.

Only thing I recall about this game is the obscure cheat code to make the announcer sound bored and sarcastic.

Could definitely see them selling additional modules for it down the line.

I recall this being the first game I had on my own SNES. I was doggie doo at it and never beat the first level.

@CookieByte Sadly this seems to happen a lot with Super Groupies, they'll announce a line of new merch from [thing you like], and it ends up looking like the lamest stuff ever.

97 brand new copies and only 5 get a 10 rating? Makes a lot of sense to me.

The FunnyPlaying kit is pretty good, though for me it's caused a constant buzzing noise, I guess from the additional power draw.

Hope it supports writing to Nintendo Power carts. The GB version detects them but doesn't support writing as of yet.
