carts go for stupid prices these days (just so they can sit on posers shelves) so they're a rip off. If you look up the prices on some of the most classic SNES games then you will see that the price of those would quickly eclipse the price of a flash cart like those mentioned above
*I forgot Top Gear 3000
Yes ive noticed this too, that was the only reason why i went for a Super Famicom, games are way cheaper so far ive bought Super Metroid $24, Mario Collection $11, Mario Kart $12, Mario World $10, Zelda Lttp $10, Super SF 2 $10, Yoshi's Island $12, all of them including shipping, my goal is to get just the ones that are sub $40 like castlevania, Ghouls n Ghosts, Contra 3, and some other Japanese stuff like GoGo Ackman which go for cheap, the ones i just cant afford are the obvious ones like Crhonno Trigger, Mario RPG, FF 3, Secret of Mana, Ninja Gaiden trilogy, Megaman x1-2-3 and stuff like that which goes for around a hundred each, no way im paying those prices.
I dont have money to burn, but i want to build a decent collection just for the nostalgiua factor, at least the ones i had as kid and sold for i dont know how much years and years ago.
Ill check that Power Pak you mention to see hows the compatibility.
fginally, im pretty sure there's a ROM hack for Yopshi's Island which lowers the volume of the baby screams or removes them completely.. im sure ive read on some hacking forum years ago but i dont know if it was actually finished or released.
