@sleve_mcdichael well, it works now.

Try leaving the configuration file aside and use the Core Input Remapping menu in RetroArch to map the L2/R2 (or other buttongs) to the PC-Engine's gamepad buttons, test it in-game, then save it as a game remap.

@bberlin1 unfortunately you probably will have to

@mitu Yep, same result as you. API issue. I'll wait it out. I'm sure they are trying to get their servers to behave.

The game is not unlike other platform games of the era. Though it's unique in that you can climb walls and swing on rope with your teeth and your only method of attack is head butting enemies - straight forward or dive bomb style. The game starts off with simplistic point A to point B style, but focuses more on exploration in the later stages, which include finding hidden bonus areas. The game is also known for its trademark gameplay mechanism of 'spin attack', where Bonk floats through the air if you have the turbo button on. This can be used to float around the level and reach areas for extra/hidden items, but also as a method of attack as well. The game starts you off with 3 hearts, but allows you to increase this number when you find special heart container items, allowing Bonk to take a number of hits before dying. A variety of bonus stages can be found throughout the game, which provide bonus points upon completion and thus resulting in accumulating extra lives. Enemies themselves can be 'milked' for points in that you can keep 'bonking' their dead bodies and not letting them hit the ground. Spin attack is another method for doing this.'

@Gobon-Shiteinga It's a Windows only game, so I'd say no - RetroPie doesn't have an included emulator for it. If you're using RetroPie on a PC, then you can use Wine to run Windows games.

So... Crop overscan does nothing when I set it in video settings.
However, there IS actually a first/last scanline in the emulator options, which allows you to essentially move the problem off screen. This seems a very "dirty" way to deal with it though (as I'm having to crop off some of the bottom few of the 240 lines).

Unless your space is at an absolute premium, then I have all ROMs unzipped, except FBA and MAME as they MUST be kept zipped

Some emulators don't like zipped files unless a specific version of ZIP was used even if they do support ZIP archives, plus it lets you know if any archives were corrupted

@xtoddh which emulator? Try both the supergrafx and pce emulators. I agree with @jonnykesh it is most likely bad roms.

So i fixed my issue...did a crc check on the syscard.pce bios...it was the wrong checksum. Finding the correct checksum bios solved my problems.

Sorry to bring up an old post like this, but to complement the solution above, you can set your system to look up for both systems (CD and not CD) but not others in es_systems.cfg : <platform>pcengine pcenginecd</platform>.
I found that from source code but in no documentation, so there is no guaranty it will keep working in case of future code change.

Added Atari 800, SNES, and Super Famicom.

@tapmantwo

However, I can't get the controls to work

I'm not at my RPi right now so I'm going off memory.

First, look in /opt/retropie/configs/supergrafx/emulators.cfg and make sure it's got the line:

input_remapping_directory = "/opt/retropie/configs/supergrafx/"

Then copy/overwright the contents of /opt/retropie/configs/pcengine/ to /opt/retropie/configs/supergrafx/

This should copy over the same controls you are currently using for the PC Engine/TG16.

From my understanding there wasn't any region protection for the CD based games and I remember trying some Japanese CDs in my TurboGrafx CD and TurboDuo about 10-15 years ago. I was surprised that they worked so well then!

I did some more research (or googling) and found a 3rd System Card v3.0 that is identified as being from Japan with an md5sum of 38179df8f4ac870017db21ebcbf53114. I tried Mirai Shounen Conan and Sylphia and they both worked on this BIOS. I also tried that 4 in 1 Super CD for the US Turbo Duo (this is the same one I had for my Duo which is also in storage lol) and it worked as well. The "System Card interface" looks just like ff1a674273fe3540ccef576376407d1d with "PC Engine" and "1991".

Also I was able to verify that the md5 of 0754f903b52e3b3342202bdafb13efa5 is indeed the USA version.

I updated the wiki with this:
https://github.com/RetroPie/RetroPie-Setup/wiki/PC-Engine

I ran out of time searching and didn't get to look up ff1a674273fe3540ccef576376407d1d to see if it was just another Japan or maybe Europe?

Network mount of just the roms folder worked perfectly for Odyssey. Very nice call.

I was hoping it would somehow also fix the TGCD issue too but no dice unfortunately. Any thoughts there?

@Pyjamarama most games arent compatible with the six button controller and thats what happens. You need to play non six button controller games in 2 button mode. The only non cd games that use the six button controller are street fighter 2 and strip fighter 2.

Great! Glad you got this working correctly!

Yes, what you put between <theme> and </theme> in /etc/emulationstation/es_systems.cfg refers to the corresponding directory in /etc/emulationstation/themes/<CURRENT THEME>/. There is also a theme.xml file in there that it uses to know what graphics to show.

Here's a tutorial to help you create your own ES theme:

@edmaul69 You are my hero! That did it. Ok, now I understand what is going on better. Thank you very much!

nope putting the syscard3.pce in the directory as the cd images didnt help. havent found a program to convert a iso/wav/cue to a bin/cue yet, and as for the xbox controller issue, the pi recognises it, but a joystick test program doesnt read any inputs from it, its one of the newer xbox one controllers 16 something.
