Hi, I am posting a guide for injecting Turbografx 16/Pc engine games. I am just posting it, I am not the creator. First you need a legitime virtual console game to do this, also you will need a Hex Editor Locate the file pce.pkg in the VC game folder in this case the R-Type Folder. Open pce.pkg in a hex editor (make a back-up if you aren't confident). You now need to locate where the rom file is. This can be easily done by downloading a copy of the US R-Type rom. And opening that in a hex editor. Then copying the opening few rows of hex. Return to PCE.pkg in the hex editor. And search for the hex values you just copied from the R-Type rom. You have found where the rom is. Delete everything from the hex value 78 onwards. You'll end up with something that looks like this..... Now find a rom you want to try out. Open it in the hex editor, select all and cut. Paste it into pce.pkg and save, injection done. See if it works. Disclaimer: This guide wasnt made by me, it was made by HerptyDerpty , so I can't help you if this isnt working.
