Bahamut Lagoon Patch
Today I was digging up some old games and one was Bahamut Lagoon. The problem is I can't seem to get its patch working. I'm using the old Dejap emulator 1.3 patch. I used NSRT to check the ROM and it's checksum is good. No header, not interleaved. Auto IPS patching is enabled and it doesn't work. So I tried hard patching it and the result was the same.
It's been a long time since I've done anything emulator related, I don't remember anything, what could be the cause of this?

I recall a bad strain of Bahamut Lagoon dumps, so you need to check on that. It is also best you get the copier patch instead of the emulator patch of Bahamut Lagoon for the best experience (there's a few bugs in the emu patch last I recall).

I went ahead and got another ROM and verified that with NSRT and tried again and the result was the same. Perhaps the patch file itself is corrupted, I have had it for an extremely long time and there have been hard drive issues since.Deathlike2 wrote:I recall a bad strain of Bahamut Lagoon dumps, so you need to check on that.

I was going to take your advice and get the copier patch but I'm not quite sure where I would get it. Dejap has been dead for an eternity I assume. I found this: http://dejap.eludevisibility.org/bl.php but the links for patches are down.
I guessed that might be the issue and added a header with NSRT and that didn't work. Perhaps the header I added with NSRT won't work?Killa B wrote:You need to patch a headered rom.

The header NSRT added should be fine.Cyrus wrote:I guessed that might be the issue and added a header with NSRT and that didn't work. Perhaps the head I added with NSRT won't work?
Maybe it is your copy of the patch that's causing the problem. I got the patch from here.

Thanks for the link. So with the new files I tried adding the header to it then auto IPS patching which didn't work. Then hard patching and the result was the same with both the emulator and copier patches. Something funky is going on, I must be doing something wrong.Killa B wrote:The header NSRT added should be fine.Cyrus wrote:I guessed that might be the issue and added a header with NSRT and that didn't work.

I'm using ZSNES 1.51 and NSRT 3.3 (I don't even know what the website for that is anymore), here is the ROM info (before I add a header) for what it's worth:
File: Bahamut Lagoon (J) [!].smc
Name: Bahamut Lagoon Company: Square
Header: None Bank: HiROM
Interleaved: No SRAM: 64 Kb
Type: Normal + Batt ROM: 24 Mb
Country: Japan Video: NTSC
ROM Speed: 120ns (FastROM) Revision: 1.0
Checksum: Good 0xB856 CRC32: 1B83C440
MD5: 5254A985EDC33928BB8535151A668080

That's what I did. What I tried patching with is Lunar IPS, could that be the problem? I assume something else is the problem because the auto patching should work anyway.Deathlike2 wrote:Add the header first, then you patch. You fail if you do it the other way around.
Don't add an NSRT header either.

Yes I did. I took a look at that again now and it didn't show. I deleted the ROM and re-extracted one from the 7z to try again. The result was the same, the first time it would show the header as added then when I check it again it wouldn't show. I figured NSRT must be corrupted so I deleted and replaced it and sure enough that was the case. The auto patching works now. Very odd.Deathlike2 wrote:Did you check the ROM to see if the header was added?
Thanks for the help guys.
Edit: Oh and just for the hell if I tried to see if an NSRT header would work as well and it does. What was the reason not to use an NSRT header?

Yes that's what I did. I added the header, selected the ROM again and it would show the header added. But then if I checked again after that it wouldn't show. As I said in my earlier post I tried again with a fresh ROM (even though NSRT probably wasn't adding anything anyway) and the result was the same, the first time I re-selected the ROM it would show as added then afterward it wouldn't. Replacing NSRT got it working.Deathlike2 wrote:When you update using the add header option, the info doesn't display properly the first time. You need to select the ROM again to check its updated properties.

You people should learn to ipsedit instead of fucking up your roms.

There is literally a program called IPS Edit? Anyone got a link?creaothceann wrote:Just run the program from the command line, it shows how to do it.

NSRT 3.4? Is there a manual or would someone mind explaining to me how do I use it to edit an IPS file?Killa B wrote:http://www.romhacking.net/utils/400/Cyrus wrote:There is literally a program called IPS Edit? Anyone got a link?
