Hey guys, I've finally decided to tackle the emulator issue that made the game unplayable when Sonic 1 was selected as base DLC. However, because this is a bug of such bizarre nature (seriously, a bug that only works when a certain game is selected?), I will require some assistance.

I have uploaded a separate version of the hack and tagged it as Sonic 1 DLC: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=708606499

Everyone who wants to help a little is invited to test it out! All you need to do is to is play the game normally and report any quirks or game-breaking things you find.

Thank you!

On it, will deliver a progress report as soon as possible.

EDIT:

Progress Report 1:

Oh jesus, this doesn't look right.

Everything seems to be in order all the way up to tutorial places gravity manipulation section. In certain places (for example, the left side of the metal "stalactite" you have to fly under) the game will freeze for around 40ish frames* and the soundbyte that was last playing will repeat itself source engine style. Afterwards the game continues as normal untill after the "One hot day" cutscence, the dialogue afterwards freezes the game and replicates the same effect as explained earlier indefinately, although one thing to keep in mind is that I was using the start button to skip dialogue.

I can't test anything else without a debug/level select build or untill this is patched. I'll try to get more indepth of an analysis later.

Tom.
