Thanks for this post, however the zeldix attachments are only downloadable for registered, logged in users unfortunately. I cannot change this.
I uploaded the patch on mega and changed the patch dl link

Merged SuperFX v1.2 + MSU patch.
[Edit]
Link removed, use fixed v1.3 posted below by Conn.

One thing that really bugs me with the original SFX2 patch is that internal header still has MarioChip1 listed under ROM type.
I did a tiny hex edit at 0x7FD6 to make it show as GSU2 (13 to 15), as it ought to be now that it's a SFX2 game.

Also, idk why a v1.2 rom is required when it clearly shows as v1.0 after SFX2 patch is applied, that's why I chose v1.0 as base rom for merged patch.
See what I mean:


[edit]
Doesn't seem to be compatible with newest v1.3 SFX patch, just a blank screen even after expanded to 16mbit.

Thank you, it works again, after a little tweaking, that is.
For some reason physical rom size, not just internal, must be 16mbit when MSU patch is applied or else it gets stuck on same blank screen.
Here's a merged patch for v1.0 rom CRC 0BAE0941.
(SFX2 patch "downgrades" v1.2 rom to v1.0, maybe that's an oversight on behalf of Kandowontu, idk).

I think you applied the 1-3_msuOnly.ips? That does not expand the rom and result in a crash, while the "vitorSF2_1.3_MSU1_Merged.bps" (merged msu with vitor, I and namings ) does expand the rom to 1.5MB and no crash, am I correct?
So the patch I posted (merged.bps, expanding the rom to 1.5MB )would work for you as well?

The original patch from vitor does some strange thing on the rom size, I think they mixed up the $200byte header or something, at least the patched rom is missing some bytes at the end.
Somebody should tell vitor to fix his patch (rom size + internal header cartridge type 0x7fd6)... but honestly, I get tired cleaning up my codes behind him - no offense, his work is great and awesome, it's just the need to adapt my code everytime he provides a new version. Happened quite too often in the past.

I tried "vitorSF2_1.3_MSU1_Merged" first, output rom is 12mbit.
That didn't work until I padded it to 16mbit, quite odd since there doesn't seem to be any data other than padded "00" or "FF".
Just to make sure, I also tried "v1.3_msuonly" on a SFX v1.3 rom padded to 16mbit, that worked as well and checksums matched.
So, all's well as long as physical and internal rom size is 16mbit, which they are with the patches I linked in my post above.

Btw I made a typo in the 7z I upped.
It's not Vitor, it's Kandowontu who did the patch, with help from Vitor.

Yes, all's good.
Thank you, Conn.

I get an error when unzipping the corrected version. It says Header Error for the bps and ips files.

Hi and welcome on board
Unfortunately I have dozens of other projects and just no time ... I hope you can help yourself

 Mon 20 Dec 2021 - 8:24 by kandowontu

No problems, keep up the good work

Really sorry. If you have particular questions/problems though, feel free to come back at me.

You could try to make the normal msu hack working in your sfx2 patch:
https://www.zeldix.net/t1805-star-fox
Direct Download Link:
http://bszelda.zeldalegends.net/stuff/Con/Star_Fox_msu1_R2.zip

In the dev folder you have the asm:
v10_msu.asm: msu source code for version 1.0
v12_msu.asm: msu source code for Rev2
v10_video.asm: video source code for version 1.90
v12_video.asm: video source code for Rev2

I corrected the jumps and code in above merged patch via hex edit, but maybe you can implement the source in your future versions the better way

The code looks clear as day, it’s the hooking out of the normal bgm routine and into the new routine that I think I’d get stuck at. Thank you for the kind words! The next update is going to be absolutely massive, with a second new map screen and 3 brand new courses, so keep your eyes peeled

If only we could figure out how to add it to the original source, we could have msu1 native

1st try: Music playing, also hitting the start button at the title screen doesn't lead to a crash anymore (the following MSU1 video pays fine).

Seems to work fine aster 1st look. Thanks a lot, Conn

So... can somebody clear me up what this patch actually is (surely I know SuperFX 2 and Fastrom), but it is like the SFX2 patch in first post further advanced?

I find these two patches on romhacking:
Star Fox Super 21 MHZ v1.4
https://www.romhacking.net/hacks/6333/

and
Starfox FASTROM 21MHZ SuperFX v1.0
https://www.romhacking.net/hacks/6443/

I guess the second is the first v1.4 advanced with fastrom to make it even faster. My question is, do we need both msu patches (and I add the fastrom ported patch to first post) or is the fastrom 21MHZ the new standard (and I replace the 1.4 21 MHZ patch with the fastrom 1.0 patch)?

I'm a noob when it comes to Star Fox  and a bit confused here, sorry.
