I was searching both Famicom Yoshi games and they are missing on the website
I found a Chinese Game Boy version at my local pawn shop:
Bought it out of curiosity. The PCB is thin and a little corrosion had damaged the traces, but my brother (CZroe) was able to fix it. Apparently it's not a bootleg. Official games were made as cheaply as possible to compete with bootlegs in that region.
Madness , the NTSC version of Yoshi , is... yoshi , the PAL is Mario y Yoshi , and the Jap is Yoshi Egg , im sure that Yoshi's cookie is Yoshi no cookie in japan , i put in "find a game" Yoshi , Yoshi no , Yoshi no cookie , yoshi egg , and nothing
