- Added Shin Akuma lose portrait at continue/game over screen

Again, make sure to use the MSU file included with the patch, and that you're patching a fresh unheadered ROM (CRC-32: 9C59DDFF).

Any further issues could be down to your SD card, your SD2SNES or the SNES itself. ikari has diagnostic firmwares to test for issues with SD2SNES.

I can try to patch with the full version and see if that works.

How can I tell if the rom is unheadered. What is the CRC-32: 9C59DDFF and how to I check that?

You can drag and drop your original, unpatched Alpha 2 ROM into this page and it will tell you the CRC-32 value: https://emn178.github.io/online-tools/crc32_checksum.html

I get this result: 0d65f4cd

Also, I changed the FXPak Pro to auto adjust for region...and that kind of worked.  I played through and it would go black randomly.  I played 5 rounds before it went black...then reset and only got 2 rounds...tried again and actually played all the way through the game...tried again and it went black on the 3rd opponent.

EDIT: I redownloaded the ROM and got the correct checksum. So I downloaded the patch again fresh. I applied it per the .txt file with flips instead of lunar ips. Had the correct file names. It boots up, music plays fine, then...again getting a black screen.

Do you by any chance have another SD card you could use for your FXPAK? It sounds like there might be a bad sector in the SD card. While it's a very low chance of that generally happening, there is a chance that could be the problem. Or the pins in the FXPRO could be slightly dirty, and might need a cleaning.

Why the game sometimes mute the sound effects when you hit with a punch or a kick to your opponent?.

It happens with the original game unpatched too, i think.

The only change is that i added all phase 1 "Z" frames, thanks to GFX2SNES.
pcx2snes and superfamiconv couldn't, due to bugs.

Now both "Z" sequences have all frames.

So far it just seems to be a bug only for sd2snes. I played it on my mod PSC on snes9x, hi rez blending on, and sprite limits off. No bugs like what was described for sd2snes. Game plays awesome. 😃

I don't care where it work.
I care if any other user have this problem in SD2SNES (if at least one say that at his SD2SNES is working, i'm gonna follow another route).
So please answer only to what i'm asking, it's simple.

Resume: Polargames, how does it react in your SD2SNES? Clear short answer please.

Then you misdirect me saying "So far it just seems to be a bug only for sd2snes".
I thought that you test it and confirm the bug.

No, what I ment was it must only affect sd2snes hardware. I emulate the game when I play it and the bug did not show up. I hope that clears things up. I do not mean to misdirect you at all.

rafadorock4 wrote:Hi Guys!

Thank you @Gizaha for the amazing optimization work. And thank you all the team for giving a real life to this title in SNES!!.. I played this latest update for some hours yesterday on real console 1-CHIP with SD2SNES and I found 2 bugs.

1 - When selecting Shin Akuma for P1 to play against the CPU, sometimes the CPU plays against itself and P1 cannot do anything else, just pause / unpause.

2 - When using normal Akuma with red cloth (select with HK), sometimes the second oponent will be Dhalsin. When this happens (it is random) after the Round 1 > Fight the game freezes. MSU1 music continues to play. No more commands are possible, pause also doesn't work.

Again, the game is amazing. Thank you for everything. I hope the problems you guys had in the past are solved and forgotten for now, so that this work can continue forward.

Please, does Gizaha have a Patreon or something? I would like to contribute and donate to him!


Hi Gizaha,

I also had this issue on FXPACK PRO Krikkz and SD2SNES Rev. X china with Firmware 1.10.3. In Firmware beta it gave black screen.

@gizaha good night, how are you?

Anyway: I also have the same problem,
I just confirmed this here!

My SD2SNES is the last revision before FXPAK PRO is released, I am using the latest released update,
I also have all SD2SNES hooks disabled!
