Now go to your Desktop and check to see the file's size if the File is 256KB, congratulations! You just ripped the UPMEM and can now declutter your ROM space. Now save this file anywhere you want personally I would save it to the Desktop first before putting it anywhere, Name the file sk2chip.bin and Save it. and in the new file just opened press Ctrl+V it will pop up a window asking you if you're sure you want to paste click yes. In the box that appears paste that offset only replace the X with another 0 so it will be 00300000 from there highlight all the way to the end of the ROM, then Ctrl+C that bad boy.įinally in HxD go to File>New. Remember the offset I mentioned? This one: 0x30000? Yeah open your Knuckles in Sonic 2 ROM in HxD and simply in the HxD menu go to Search> Go To. A Knuckles in Sonic 2 ROM (Can be Deleted after) Same goes with Sonic 3 & Knuckles no extra ROMs are needed once the UPMEM is extracted and if you back it up. It also allows all ROMs listed above to be played Locked On or Alone thus it's like having the KiS2 ROM in your back pocket.
Simple it helps tidy up your ROM library, so instead of having: No, find a Retrode if you can and rip your own cartridge ROM, then use that until Sega Releases Knuckles in Sonic 2 for Sale.
The ROM from the Knuckles in Sonic 2 Disassembly WILL NOT WORK as we have recently discovered the Disassembly on Sonic Retro for Knuckles in Sonic 2 is severely unfinished, thus serves literally no purpose. Everything before is data from Sonic 2 or Sonic & Knuckles. This is where the UPMEM is located in the Knuckles in Sonic 2 ROM, and it spans to the end of the ROM. I plugged in my rom size and got a result I then gave the result to DaKingofDaCheckerz who then finished of the calculation and gave me the final offset: 0x30000 KiS2 ROM Size - 256KiB (Keibibytes) = ? MiB (Meibibytes) Until I joined the Sonic 3 Angel Island Revisited Discord Server and RawData I asked around and was told to find the right offset I needed to do some Math: (I know as when I tried going to the location they gave me the Hex Editor couldn't find it.) Second that it could be extracted with a HEX editor, and a post incorrectly detailing where the last 256KB started. What I did find was some info: First that the UPMEM was the last 256KB of the Knuckles in Sonic 2 ROM. This meant I couldn't lock on, I searched all over the internet, and couldn't find the UPMEM ROM. There was just one Problem- While I did have the Sonic & Knuckles ROM I was missing the required UPMEM ROM. I tried getting lock on to work for the sake of decluttering my ROM list and to play the games as intended in a purely digital format.

In Sonic 3 and 1's case this isn't necessary but this chip is still a requirement for these games to run the intended code. However it's also involved in the process of checking the Lock-On game, namely to see if it should boot the Knuckles in Sonic 2 Data. The built ROM will be called 's2built.bin'.The UPMEM is a chip in Sonic & Knuckles responsible for patching Sonic the Hedgehog 2 with Knuckles' Art, His scripts, and the Level Design Changes made specifically for him.

To build this, use build.bat if you're a Windows user, or build.sh otherwise. A disassembly of Sonic the Hedgehog 2 for the Sega Mega Drive/Genesis. The classic tunes include new themes for every zone and more sound effects, along with the ever-classic Sonic repertoire of pings, plings, and sound bites.
