Newcomer's Board / Re: Just Curious About PSX Disc Patching
« on: May 10, 2020, 09:40:55 pm »
How does one patch a physical PSX disc? Even though I don't own an actual PS1 or any game discs associated with it, I've been wondering for some time. I'm willing to one day get a physical PS1 and a copy of MR2 so I can apply STARWIN's patches to the game, IF the North American version of MR1 makes it to Switch sometime in the future.

No idea what MR2 is but you patch the ISO and burn it to a CD-R.

In DeltaPatcher you can choose to apply the patch by ignoring the checksum check. You can at least see if the patch works, after disabling the check.

It does not work after disabling the check. Two emulators refuse to run it.

You have 2 different roms, romA and romB. Make copies of them, then change a single byte in these copies, let's say write FF at 0x1234. Then create patches using xdelta. Now you have 2 same patches, the only thing that should be different is a checksum taken from original roms. And this difference you will see in comparsion, which will point to location where xdelta stores checksum. Find this location in your wanted patch and take checksum from it.

Now that I think about it, there is an easier way. You can make any patch for any rom, and since you know this rom checksum, you can just search for it in a patch

Seems that it would be just as easy, if not easier, to just attempt to run the patch on all these roms I'm collecting to scavange checksums from.

Okay. In this one instance, I figured out that the problem is that the romhacking submission is incorrect & the site does not verify submissions. The article has the wrong checksum listed; another dump worked instead.  Wonderful. Gonna be lots of fun trying every possible dump for this folder full of failed xdelta patches I have.

How does one go about reporting this?

There is a theoretical way. You need to create the same patch with xdelta for 2 roms with different checksum, then compare these patches in a hex editor, and the only thing that should differ will be checksum. Then find the same area in your wanted patch

I'm sorry, I've read and re-read this and I don't understand the process here. I need to create a patch? Of what, how?

Two usual things to check
1) That you are using the right ROM.
2) That you are using the right version of xdelta.

1) As I said, the checksums match.
2) I have XDelta 3.0u, 3.1.0, and DeltaPatcher.

Maybe the patch's documentation about which ROM is required is wrong? Is there a way to get XDelta to tell you the checksum that it expects to see for a certain patch, rather than relying on ROMhacking info pages?

So I've been fiddling with roms since the 90s and patching files just about as long. Lately, though, these Xdelta patches have been giving me hell.  I'll confirm that the CRC32 and/or SHA-1 checksum match what I'm supposed to have, but Xdelta always refuses to patch, saying xdelta3: target window checksum mismatch: XD3_INVALID_INPUT. What gives? Is this some 32/64 bit or admin mode tomfoolery?

Hey guys.

At first I want so say thank you for the great work with this hack.

I have a question. Is it possible to play this game on the EverDrive GBA x5 with the GBC emulator on a Gamecube - Gameboy Player?

Sure, you can use one of these too if you've got a SNES->GC adapter.

WinRAR is a better program than 7zip. 

How so, if it can't open a RAR?  It's 2018, get 7zip already.

I kinda thought it was intentional.  In some games everyone not knowing or forgetting Luigi is a running joke.

Really though... he's just 2p mario, he's not a character.

I guess Super Mario Land 2's 25th Anniversary should be celebrated, shouldn't it?  ;D

Click on the image to download a small teaser demo:


Awesome work! Looks amazing so far and it's been a treat to actually get to play it colorized.
Only suggestion I have is that the hitodama/onibi (flame-looking ghosts) on the map and in-game should traditionally be blue rather than red.
