I uploaded all the patch.zlib files I could find for Gen games that had been released up until a month or so ago here.
Nice, are all of those US releases?

Are these things being applied in real time now, or am I missing something? =|

Some patched ROMs may be precompiled, but anything that's packaged with a patch.zlib file appears to load the original unaltered ROM and then apply the patch in real-time over top of it.
Wait, this can't be correct. I remember extracting the Alien Soldier ROM and it had the NTSC-U fixes already applied to it.

This is why M2 > Backbone folks! Are they still doing the VC ports? We're talking the same guys that remade Fantasy Zone II as a brand new System-16 game, compared to Backbone not even doing simple patching like Sonic 3 & Knuckles on Ultimate Collection..

Well... thanks to Backbone, PS3 and Xbox owners have Spider-Man in Revenge of Shinobi, instead of Ladybug-Dude. =P

They did, in Live Arcade, something that M2 still haven't done on the VC...

I so want to see that as a Virtual Console Arcade release.

I never thought of that. That would be so fucking awesome.

By the way... I suppose there's no program out there that can apply these patches automatically to the ROMs?

I just wanna check out what changes they supposedly made to the title, since nobody seems to have noticed any, yet the patch makes mention of them.

Indeed. Take WAD file from SD card, run through wadunpacker or similar, then use U8tool to extract the contents of 00000005.app and subsequently data.ccf. Then you end up with a folder with the ROM and patch in.

IceKnight - you can just edit them in yourself with any hex editor - I've done this with my SF2 ROM to try and figure out what the heck they did.

You mean, typing all these values by hand?

Well if you really want to play Genesis VC roms - grab the WAD file and load it up in Dolphin. I can play Pulseman, etc. :P

Some games may not work, but, the majority of them do. You need a nice PC to run everything, so just be sure you enable the lowest settings when you play.

Also don't forget to configure the Wiimote plugin for Classic Controller usage (also - be sure to assign keys to the controller to). smile.png

My pc's so good, I should be able to record video of games actually running on the emulator. Although, I don't really have patience to make it all the way up to the Spiderman thing in Shinobi. sad.png

EDIT: Idea of the century, maybe you could run a VC game and run some kind of memory/process attachment program to manually pull the patched roms directly from memory? It worked with PCSX2 for getting the Phantasy Star roms out, and it also worked for Sonic Mega Collection (I think). So give that a shot...

Anybody tried this yet? Just wondering.

I got the memory dump of Phantasy Star II when it's loaded on the Wii. From the looks of it, and I'm just assuming this, it loads both the Original plus the newly patched version in memory at the same time. I don't know how to extract the rom though, but it should be easy for people are who used to using Hex Editors.

You can grab the dump here.

I'll find a way to get more games as soon as I get them again. If you want to join me, load Dolphin-Emu in debugging mode (make a batch file so it can load the main executable with a -d flag), load your game, press Play, then open up the Memory tab on the left (it might be tucked away on the left, so drag it out so you can see it.), then finally click the Dump Memory button and Dolphin will crash. You can find the dumped RAM in User\Dump\ram.raw.

Erm, just found this.

CODE
SEGA MEGA DRIVE (C)SEGA 1988.NOV
PHANTASY STAR 2       BACKUP RAM
PROGRAMMED BY          NAKA YUJI


Hey, at the very end of the ROM, it says:
CODE
GREEN CROSS FIX.


By the way, both copies of the ROM inside RAM seem to be identical (patched), made from version 02.


EDIT: Uploaded here (with its internal name).

Note to those confused: He means "EUropean", not "Europe + US". The ROM inside is PAL.


EDIT: And it looks like there's no dump of the PAL version on the internet? Could you please also extract the ROMs inside the WADs, so we can compare them with the known dumps?

EDIT 2: Hey, in the case of PS4 there are two different ROMs indeed!

EDIT 3: The internal name (for the unpatched one?) is PhantasyStar4_Europe.SGD, by the way.
