Pushing to Core as soon as I update the achievements to deny cheats...

EDIT: I'll update with the actual changes in a moment.

What is the possibility of adding the score system to this games leaderboard?

I'm aware that there is a problem with farming and exploits, but I think this would be worth looking into as the score in S3&K has been a fairly ignored aspect of gameplay, but could make a fun addition if included in the leaderboards or having personal bests for each level was recorded.

A little sniffing around reveals that there apparently IS a points based leaderboard for S3&K.

http://retroachievements.org/leaderboardinfo.php?i=553

It doesn't look like this is activated/implemented/working though. Or maybe it's just a placeholder. Does anyone know anything about this?

It looks like they shifted it to an address that will never function for the START parameter, so the leaderboard will never start. It does have some code in it, but it looks like it was intentionally put away rather than being deleted.

It's unfortunate, but there's only one cancel-condition for leaderboards, so if they have no way of getting around points-abuse, they probably decided to get rid of it for the time being. Maybe they planned on getting it fixed at some point but just never got around to it, who knows.

Noting rich presence bug: RP text: "Unknown"

when i finished marble zone with sonic, nothing happened :/

did this happened to someone else? how i fix it?

A rom indicada no post inicial está certa? Eu achei a rom como "Sonic & Knuckles + Sonic The Hedgehog 3 (World)" e não como "Sonic & Knuckles + Sonic The Hedgehog 3 (USA)".

---------------------------------------------------------------------

Is the rom indicated in the post right? I found a rom like "Sonic and Knuckles + Sonic The Hedgehog 3 (World)" and not as "Sonic and Knuckles + Sonic The Hedgehog 3 (USA)".

The old icon was outvoted and replaced, here's a backup of it:

The old icon was just epic, except for the logo and writings on the bottom
. But I understand =/

The old icon was outvoted and replaced (again), here's a backup of it:

The checksum: cfcc692427348e58682230a27d9e365d is not compatible, dont know if I can add it myself (I tried but it gave me an error)

The Checksum is from the official steam version of Sonic 3 and Knuckles (https://store.steampowered.com/app/71162/Sonic_3__Knuckles/)

Created new conditional Rich Presence, old one was basic and relied solely on currently playing music.
