It's a pleasure! :)
JonnyRetro 25 Jul 2018 12:47
Thank you so much! Finally some 8-bit sonic love <3
HeisenHower 31 Jul 2018 02:07
"Mecha Green Hill Boss No Touch Ground" dont seen unlock for me i've tried every way( sonic, tails, level select, normal run) i even change the rom. Does anyone know how to do it?
TheRockXXL 4 Jul 2019 07:51
Could you copy these achievements to the Master System version please?
Nimta 15 Jul 2021 08:33
The master system version is different enough that some of these might not actually work in their current form.
MusicalMinerdude 19 Aug 2021 01:23
Neither "Mecha Green Hill Boss No Touch Ground" nor "Hidden Treasure" seem to work... It's a shame. This is a great set otherwise.
MusicalMinerdude 27 Aug 2021 06:40
Update: Turns out some of these are acting strange with the JP ROM after all. I'm hoping to get through the rest of them with this knowledge in hand, but it would have been nice to have these oddities fixed. (At least I got Hidden Treasure on the international version.)
MusicalMinerdude 27 Aug 2021 08:15
Further update: I see why the MGHZ boss achievement is so frustrating to get now. The boss has more HP in the international version, meaning it's tougher to stay in the air while you're killing it. *Great...* I never even knew this until a recent experiment
ikki5 27 Aug 2021 12:13
I'm not even sure why the JP rom is even there, we never used it in the making of the set.
MusicalMinerdude 27 Aug 2021 21:14
Huh... Well that's a bit awkward. But regardless, if I must deal with the version that was used for this very last one, I'll figure out a way to complete this set. (I'm stubborn lol)
MusicalMinerdude 3 Sep 2021 21:38
I finally got the timing and placement down! Set complete, and that's my first time ever managing a complete set here. ...This was fun :)

Mastered!
KawaFernandes 20 Jul 2022 20:56
⠀Mastered & Tails! If you wanna make it easier, open it on RetroArch, using Genesis Plus GX core, press F1 to go "Quick Menu", then go on "Options", then "Video" and turn on the "Game Gear Extended Screen" option. Reset the game and you'll play the game with a Master System resolution!

(The Master System version should get achievements, too.)

Master number 5! Easy set, but some frustrating parts here and there.

Mastered! Pretty chill set

A wonderful game. Much more polished than the MS version. Also a few differences on levels layouts.
