Indeed!!! I am sorry, I had not pay attention that it is because of the SA1 patch that is rewriting the same value present in the original ROM in those three blocks. I am sorry, I have just read your SA1.txt that is clearly asking to apply SA1 first instead of MSU1 (what I have previously done). My bad for do not checking it before posting.

Really no need to apologize, I'm happy if other check my work
I think the SA1 needs to be applied first either way since it's bps format

Yes, but I am used to convert BPS in IPS format mostly immediately to add versatility in case of multi patch or in order to test them on other ROM regions if relevant from my viewpoint (which is why I was able to point that non problem).

Writing that I "check" your work is unfortunately little exaggerated because I do not understand programming, but I can use logic to at least find abnormal things (or not in the present case).

I updated the first post with the dimension pack by SuperFeistyFox.

Unfortunately, it seems mega.nz has restricted the files with DMCA as we already experienced with Google Drive, 2 of my files needed to be rehosted on mediafire. Also MF had these files on a blacklist, renaming the file did not help (guess they calculated a hash value and if match they immediately take it down).
A workaround is to store the files into 7zip instead of zip, since this will result in a different hash. Let's hope that we have some silence for a while now...

Anybody with files on mega.nz please check the notification if some of your files have been taken down:

Sorry conn, i don't keep files in mega.

Files in 7zip maybe only a temporary solution, better using another host.

Yes, problem is that MiniComputer's Rock 'n Roll PCM for super metroid was flagged on mega.nz, I rehosted it on mediafire and it was flagged as well there (immediately). So I wondered why they know it (renamed the file, still flagged), so there must be a hashing algorithm running which can be avoided by changing the archive file size or recompress it with 7zip (my solution).

But I think onedrive, google drive, mega.nz and mediafire - they all DMCA stuff so I do not know a reliable host. Best thing we can do is changing the host if one or the other pack gets flagged.

Forgot to point out that my PCM pack maintains some tracks done by FullGameZone, so he should get some credit too.

Done, if you want to describe further (e.g. differences) just write them here and I update

Unlike the other pack, which contains mostly fan made recreations of tracks from the SNES game, which are nicely done by the way, my PCM pack contains a lot more tracks from R-Type 2 (Dimensions version). My tracks are according to what I think adapts from the arcade game to the SNES game to the best of my knowledge.

Mmm... Idon’t know if i’m doing something wrong...

Do the “SA-1 compatible” enables the SA-1 performance?, or only the compatibility with MSU-1, but not the SA-1 performance...

I’m aplying the patch over the super rtype usa rom, but it works just like an normal slow rom.

Apply first the SA1 patch by Vitor Vilela: https://github.com/VitorVilela7/SA1-Root/releases/tag/v1.4 (Super-R-Type-USA.bps) on your original Super R-Type rom
THEN
apply srt-msu1_v1.1_SA1_compatible.ips

Rename this rom into srt-msu1.sfc and proceed with the msu1 instructions (copying *.pcm, srt-msu1.msu in this folder and so on)

Super R-Type (USA).sfc or smc
CRC32: 8B22C830

Thank you!!

I’m connecting through my phone, luckily i can copy files with the SD card and an usb adapter, cause i have no connection in my pc ^^u
