I was playing 3D Blast DX on Kega Fusion (the emulator I usually use for Mega Drive games), had 3 chaos emeralds on me by this point, and when I entered Tails's special stage in Diamond Dust Act 1, the whole game freaked out with the only way out of this being to reset the game. Here's a gif showing what's going on in the special stage:
This is honestly terrifying yet oddly hilarious at the same time if you ask me.
No worries. If there is anything else I can do to help, let me know.
EDIT: Fixed in Version .2.
I already checked the info you provided in my thread regarding ROM checksums, and from what I understand of checksums, it appears that the files being used are identical, even if they are from different sources. I'm not sure why I can't seem to encounter the issue, I will keep trying though.
You could get the rom and run it in Kega if you want. I would share mine, but I think it's frowned upon. Either way, told you where I found mine.
I just tried that password, I played Diamond Dust 1 and went straight to Tails, no glitches. Now I will try going to Knuckles, and then Tails.
EDIT: Tried that, still no bug. I don't know why I am unable to replicate this issue, I would really like to see this bug in action.
Maybe instead of a Save State, you can get to it with the password. Maybe using the save state prevents the bug. My Password is: 4TY72M/3492. BTW, is that save state for Volcano valley or Diamond Dust ? Could be a separete issue from Diamond Dust.
I also thought it maybe the 32x (Or emulation of the 32X.) Same glitch on my Sega Nomad. :\
I'm sure it's an actual glitch. Heck, when patches like this come out, I always rip my own cartridges cause it's always a pain finding the exact rom. I also tried the world rom as well, it still glitched out as well. Can't get more authentic that that. :p Guess we'll wait and see. :)
@DevEd, I loaded your savestate but had no errors at all. The stage played perfectly fine. Has anyone considered that a slightly different copy of the ROM is the cause of these errors? I personally use my copy of Sonic 3D Blast that came with my purchase of the Steam game, SEGA Genesis Classics.
Confirmed. Same happened to me when using my mega everdrive on my cdx.
I had a somewhat similar issue occur in Volcano Valley Act 1. Here's a savestate if it helps: https://cdn.discordapp.com/attachments/376903213376602142/382338443629297675/Sonic_3D_Blast_-_Directors_Cut.gs0
The bug will trigger when you load the savestate and then go to Tails.
I suggest keeping all bug reports regarding the Tails Diamond Dust Special Zone glitch in the same thread as to keep things organized. Also, it's nice to have an animated gif for reference, so thanks.
