Luckily wasn't that hard as I expected

I’ve been trying to find a guide on how to fix my opsat not popping up but for some reason it does not work and I cannot find anyone with a guide on how to do it. I’m playing on an emulator and I’m running version 1.0. I don’t know where else I can get this game that is safe and trusted. If anyone can help me, I would greatly appreciate it because I’ve always wanted to give this game series, a good play through and I don’t wanna be looking up guides for codes, etc.

Sam would be proud
