Yeah, well... Fuck. \o/

The crash in level 1-3 was indeed caused by a bug in higan. Cool

While this brings my character down into the shame at most, the bright side is that Conn helped Cydrak and byuu to trace it, and the next version will have this oddity fixed Very Happy

Let this be a lesson to everyone nah, just me really, nothing is guaranteed to be 100% safe from mistakes, I just feel bad for pushing Conn into thinking his code was lame, when it was actually me who refused to see beyond the horizon. Crying or Very sad

Do remember though, despite my silliness, higan is fairly accurate compared to others, if anything works on bsnes, but not higan, or vice versa, you might have undisclosed a bug in one of them, getting into the root cause will help to improve both even more, and the emulator developers appreciate very much Wink

now going to live in the mountains

What to say? We coders are only human, and I'm happy (of course not happy but miss the correct English word) that also very skilled and experienced people like byuu produce bugs, that's in the nature of coding stuff. However, in this particular case I couldn't completely reject the possibility that my code produced the bug (since no other SFX game played in higan produced any weird stuff like this).

In the end I am happy that byuu is going to fix this bug, which apparently is only present when using my code anyways Razz But I could fix my code to be not affected by this bug, so also older higan versions will have no problems running it Smile

Counterchecking my codes to work with sd2snes and higan is always essential for full compatibility and since higan is the most accurate emulator it lies also in the nature of things that it is in 99% the code which is "lame".

Anyone try this on the SNES Classic yet? I see the Nintendo logo, but after that, black screen

There is a tutorial on You tube how to run MSU-1 on SNES Classic on PC.
You just need to patch the game correctly (to the correct original rom) if you have a black screen. There usually is a headered vs unheadered rom, US vs EU rom etc. So there is a lot of instances where you can patch it wrong.

I know how to do that already. It's patched with a no intro ROM. I start it up and I see "Nintendo Presents", then it just stays on that black screen following it.

I think this is too special for our forums, try other forums that are dedicated to snes classic playing. My patch runs on higan, so it should play on snes classic as well... if
- it supports super fx emulation (does it, sd2snes e.g., doesn't)
- you patched correctly and the "no intro rom" does not affect my patch.
Check if your rom that crashes in classic still runs on an emulator to see whether you did everything alright, or whether my patch is incompatible.

Run the same patched ROM on snes9x emulator on PC.
If it works (goes pass the black screen), the patch is incompatible with SNES classic.
If it doesn't work, you patched to false original rom (do note even the No-intro rom might not have the same CRC-32 as required).

Yeah, if it's not working you need to take a step back and try to eliminate variables in order to track down exactly where the error is. Start with something that you know works, the original ROM on a PC emulator. Now apply the patch and try that again in the PC emulator (you won't get the MSU-1 audio, but at least check that it runs instead of crashing at the black screen). Now add the MSU-1 files and try again, and make sure everything is working. Once you have everything working on your PC, NOW try copying it over to the SNES Classic. Either it works, or else you know that the problem is with the Classic (or with your method of copying the files over). If anything breaks before that point, you know that you have a problem with either your base ROM or else with your patching process. Unfortunately, the patch is an .ips, otherwise if he'd used .bps you'd know right away if you had the right ROM because the patch would actually tell you that...
