Metroid super zéro mission on SD cartridge

[Nuage]

Hello! 

I'm a big Metroid fan and wanted more than the regular game, so I've bought a Super ufo pro 8 cartridge to play some hacks on my snes.

Problem is I can't get some hack to work :cry:
I've done it this way :
-got an unheadered rom of Super Metroid
-verified it's really unheadered with smile
-got the patch of Metroid super zero mission
-patched the rom with lunar

But when I try to load it on my snes via the SD cartridge, I have an error message "file type error". The rom don't even star to load.

I've tried for hours to make it works, tried to add an header, to check and fix the checksum, with a few Super Metroid rom, even one I dumped myself.
I'm not good with these things, but I tried and failed to understand what is the problem.

Anyone can help me?

Some hack work, like redesign, Justin Bailey.

Thanks a lot.

Does Super Metroid run normally? Do you know whether the cart expects .sfc, .smc or different?

[Nuage]

Yep Super Metroid run perfectly, even when I use some tricky feature of the super ufo pro 8 like the save States, it doesn't crash.

The cart expect SMC, Bin, Rom and some other fancy type I've never met.
Tried with SMC as it's the most common type I guess.

Does your patched rom even load on emulators ?
Note that most patches are made for NTSC (JU) roms and may not be compatible with PAL (European) roms.

[Nuage]

Yes the rom works fine on emulator.

My super Nintendo accept both Pal and ntsc cart.
I used Super Metroid JU to patch zero mission.
The rom without patch works fine.

Although I can read that my patched rom has a bad checksum when I load it on snes9x, my original rom is OK. Is that a problem?

I've failed to get a good checksum with the patched rom'

I'm totally lost at the moment  :cry:

When you run the unheadered, unpatched Super Metroid ROM in an emulator, is the CRC32 D63ED5F8? If not, you don't have the right (JU) version. The filename should usually be "Super Metroid (JU) [!].smc" (without quotes). [!] means that it is a verified good dump. There are various b and f versions as well, such as Super Metroid (JU) [!][b1].smc.

Try to expand your ROM up to 4 Mb.

Try to expand your ROM up to 4 Mb.

Now that's a valid point. You could also add 0x88000 FF bytes to the end of the file in HxD. Just use the 'Insert Bytes' option under the Edit menu.

I have checked, the rom is the good one.

As for the expand of the rom I'm gonna try this evening,  thanks for the tips!

Nuage, try patching this with this and see if it works.

I use a snes powerpak and some hacks have issues getting them to work.

Usually if the hack is expanded then you need to add a header to it, you can hex it in if the hack is 'locked' too.

Sorry for the late answer, I was busy these last days.

It works!  Thank you so much, the game looks amazing.
Can you explain me what you did?

I'm sure my rom was a good one, the patch too.

I want to be able to do it by myself, there is some hacks interesting me.

[M1CR0H4CK3R]

I took my working MSZM ROM and expanded it to 4 MB, then created a new save (SRAM, saved/saveable RAM, or .srm). I then used Lunar IPS to create the .ips by selecting the .srm first, then selecting the ROM. You're welcome, and I'm glad it works for you.

I use an Everdrive cart myself, however being in upside-downia I had to disable the lockout chip on my good old PAL SNES. Strangely enough some hacks worked prior to that, and I can't for the life of me work out why.
