The achievements DO NOT WORK IN RETROARCH (yet), use RALibRetro if you just can't wait to play some Sonic Pocket Adventure.

The achievements all have icons, they haven't been uploaded yet because I'm getting errors uploading right now. Same things with cover art and other related images. Expect them as soon as I can.

Icons and image uploading have been fixed, so I have added icons and images for the game. Neat!

Also double check your MD5 for the rom, according to CertUtil mine is b8a899ae2b0f1dfa0db5417de745a51e

Here is a video of me starting from scratch, setting up the emulator and rom, starting the game and getting the Hardcore Hammer achievement: https://www.youtube.com/watch?v=3rQKIPb-s2g

Ignore the fact that the emulator lags a lot, RetroArch does not lag but RALibRetro lags a lot for me. Also ignore me dying at the start of the second level...

It will get fixed eventually by someone who works on the emulators, but I do not think it is their top priority currently (considering there are only two functioning games for the platform right now). I'll post in the comments here when it is fixed.

Updated Emerald achievement so that it uses Special Stage Ring Count address instead of the previous not accurate "Bonus Stage" address. If anyone had any issues with this achievement, the achievement should be fixed now.Sorry for the inconvenience.

Good news, the game now works in RetroArch 1.7.2, so if you have not updated RetroArch and are wanting to play this game then you know what to do :)
