Super Turrican MSU V0.2 released!

>>>Update: Go check out this post for Version 0.3.

I'm happy to announce that my Super Turrican MSU Hack will now be released. Chris Hülsbeck gave me permission to publish the soundtrack with the hack which was the crucial part in the end.
You can download the hack here.

Download Super Turrican MSU Hack

Keep in mind that you need a sd2snes or the emulator higan to run this hack! Currently only the PAL version is supported!
The package only contains the soundtrack for the MSU chip and an .ips patch file. You need to get the ROM by yourself.
You are only allowed to apply this patch if you are in possession of the original.
For this you need the .sfc file of your game. Either read it back from the cartdrige or ….. help yourself in other ways.

Download JIPS or another ips patcher to apply the patch. It's very important you got the right ROM. To be sure the correct file has the md5sum of 90c9fe8386a7f69de475c58bb8de01f7.
If you patched your .sfc file put it together with the rest of the files inside the package into a directory on your sd2snes.

The package contains a README.txt which will explain the process in more detail.

That's all!

The music in this game is an altered version of the Turrican Soundtrack Anthology made by Chris Hülsbeck. If you like the Soundtrack you can buy it from his bandcamp site in lossless FLAC and MP3. There are 4 albums to get, containing not only the arranged Soundtrack for Super Turrican but also for the other games as well.

---> Very important note <---
The game has one major bug which was kinda amplified with my hack (at least i feel so). The usage of the blue laser weapon can lead to a hickup of the SPC on some SNES devices. If this happens you can hear a strange and loud noise that sounds like "frfrfrfr". At this point the game still runs but you are unable to get to the next level as the main CPU is not capable of talking to the SPC anymore.
Even a reset of the SNES doesn't restore a healthy state sometimes.
You need to cut the power of your SNES for seconds to make it runnable again.
I'm not yet sure how this happens and it kinda flaws the whole hack. The only bright side is that this flaw is actually part of the original game.

Please help me investigate. Test the game and report issues. This flaw never happened to me on the emulator higan i used to develop the hack which is a major fallback. I'm not capable of debug this issue at this state. Just try to stay away from the blue laser.

Sadly enough it's also possible to get this problem in more rare occassions with other weapons as well. I could only assume that the soundeffect playback routine has a bug that i still don't understand.

Now as it turns out this happens only on 1chip SNES and newer revisions. I will investigate!

  1. Couldn't be written any better. Reading this post reminds me of my old room mate! He always kept talking about this. I will forward this article to him. Pretty sure he will have a good read. Thanks for sharing!custom pcb
