Snes Mario World Legend Continues Patch

[lizard808uk]

Didnt know if this was the right forum or not (since its concerning hacking a rom). Basically I have a 48MBit version of Mario World with the Legend Continues Demo World Patch (Lunar Magic). Just wanted to know if there was a way of recompressing Mario (after its been expanded for the patch to be applied) or stripping out the "0"s safely to reduce the rom size (and then make it playable on GP32).

I have used Google and have a "recomp" tool , but not sure what command I should put into it.

Any help would be greatly appeciated.

48MB!?
Sorry, but OSNES wasn't meant to play anything over 4MB. I don't think its going to work.

[EDIT] I read it wrong... 48Mbit????? what the hell is that? And you should just be able to ZIP it. I'm not quite sure what you're talking about...

48MBit (6 Megabytes). Its an uncompressed rom, I'm just trying to work out how to either a) recompress (I think it uses LZH or something) or B) reduce filesize by stripping out 0's at the end of the file.

A ton of zeros? hmm, I dunno about that...

But, you should be able to compress it to ZIP just fine. If you want LZH use WinRAR.

Compression won't help you though, because OSNES needs to uncompress it to play it anyway.

it's been expanded to 48Mbit for a reason you know. if there are any trailing zeros at all, remove them with a hexeditor. FuSoYa knows his shit, it's probably already compressed to hell.

not sure if there is a way to recompress it, you'd have to ask FuSoYa. *You prolly want to play it on GP32 don't you ;P*

Thanks for the comments, I will try and email FuSoYa and see if he can help. Other than that, its a quality game. I will let people know if it can be done (if at all :unsure: ).

My justification was that the initial rom file is 512KB which is then expanded to 6MB. I'm sure its possible to recompress to a certain extent, but we'll see...

the odd thing for me is, the patch is about 100kb or so *maybe more* and when i patch the 512kb rom it turns into a 5.98MB rom *without decompressing* yet after decompressing it's 6MB, and patched still 6MB

But the weird thing is, the 2 files patched together do not even equale 5.98 MB

 

[lizard808uk]

Thats what led me to think that there were 0's added to the original file to "fatten" it up for the patch (the patch itself needs a 48Mbit HiRom to work).

If this could work on os9x, I would be a very happy man indeed

I posted this on Fu's site.... You can't do it... the strange thing is, YOU DONT HAVE TO EXPAND IT FOR ALL PATCHES. its weird. dont know iuf it works on opensnes 9x
