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.

Look I didn't make the rules. Talk to an admin if you want to question the rules

As I suspected, that .pkg file does look like the same format as used by the VC on 3DS. I figured out the format completely so you can edit the header to work with any size ROM, there's a discussion thread about it somewhere in the 3DS section of this site, plus on a certain iso site for 3DS stuff (VC subsection of CIA section), there's more discussion, ready-made .pkg files etc.

Someone could, but it's not likely to be me. Another good option would be to extract the .pkg from the various injects that have been posted on the aforementioned iso site.

Found my writeup from the iso site:

hippy dave said:
Ok let's see... description of pce.pkg:
All the sizes are stored as four bytes, in reverse byte order.

- The first four bytes are the total size of the pce.pkg file minus 4 (ie the size of the rest of the file after the first four bytes) - so you can put this in last.

- Then there are three other files stored, in the format: (four byte size of data section) (filename followed by null 0x00 byte) (data section)... so you have:

-- pceconfig.bin, which has its size listed as 0x000000A0 bytes (160 bytes), followed by its filename and a 0x00 byte, then the 0xa0 bytes from offset 0x16 to 0xb5 are its data. It's mostly zeros with the filename of the rom listed twice at particular locations, you can safely overwrite the filename even if it's longer (within reason).

-- then two copies of the same thing: the rom file stored in the previously described format... the rom filesize (which is where you saw that changed byte, because 0x00080000 is 512KB and 0x00100000 is 1MB), the rom filename (as listed in pceconfig.bin) followed by a 0x00 byte, and then the rom data. Then rom size/name/data is repeated a second time and that's the end of the file.

Would it be possible for me to inject Madou Monogatari into one of the Turbografx-16 games, or do we have to wait until they release a CD one?

It mostly likely will not work. Here is my partial explanation why.

Oh ok, great info. Would be curious to see for sure whether bank switching is supported tho, when I was poking around in the binary I got the impression the emulator's pretty well designed, they might have made it fully featured instead of just doing what was needed for the games in question (there's strings in there referencing CD ROM, tho I don't know if that means it's fully supported, and we might not find out how unless they release a CD game).

Banking
=======
Normally address spacebanks 00-F6 are assigned to regular HuCard ROM space. There
are a couple of special situations:
Street Fighter II:
- address space banks 40-7F switchable by writing to 1FF0-1FF3
1FF0 - select rom banks 40-7F
1FF1 - select rom banks 80-BF
1FF2 - select rom banks C0-FF
1FF3 - select rom banks 100-13F
Populous:
- address space banks 40-43 contains 32KB RAM
CDRom units:
- address space banks 80-87 contains 64KB RAM
Super System Card:
- address space banks 68-7F contains 192KB RAM

I also had a look and it seems there are a lot of things hinting at it supporting CD Rom games (1,2,3), this works (not sure if it's really an indication of anything though) and Ogg Vorbis also appears to be supported (which is the sound format used by the Wii version of the TG16 VC). I wish I understood these things better... it feels quite close... and, at the same time, so far away. :unsure:
