Do not push it in. If the pins do not align, you will have to bend the pins inwards. You can do this on a flat, hard surface. Place chip sideways onto the surface and use the surface to bend one side of the pins inwards. Repeat for the opposite row of pins. Do this gently and check if they align with the socket each time.
When the two rows of pins align with the socket you can bend pins 38 and 39 outwards. Remember chip pins are counted anticlockwise starting from the left. A small circle indicates Pin 1 or a half circle cut indicates which side of the chip to start counting from. This image shows what happens when you do not use Kapton tape to mask off the port pins. Solder will flow down the pins. You will then have to remove it. Compare this image to the image of the Mega Drive port. Two wires will need soldering into the module that connects the expansion ports of the Mega Drive and Mega CD.
Modules attempt to make things a bit easier on the developer by providing a somewhat generalized system for compiling code and data into binaries. You can think of modules as very small "ROMs" on the disc. This is how most Mega CD games work: the title screen is a module, the options screen is a module, each stage is a module, and so on.
It is one self-contained piece of the game as a whole. This is probably the most central concept of Megadev and having an understanding of how to create modules is necessary for creating games. See modules. Using only the built-in Mega CD BIOS calls to retrieve data from the CD-ROM is a rather arduous process of specifying a sector offset, waiting for a number of sectors to be read, monitoring the CDC as it processes the input, and then finally having the data appear in a buffer.
Megadev provides an API that wraps all this up so that only a filename and an output address are required. This is not a required component of Megadev and you are free to write your own loading routines, but if you'd like to use it, see cdrom. These user libraries are extremely useful and, in the case of the BIOS, necessary for using the hardware. Megadev provides definitions for these calls as well as C wrappers for those that are most commonly used. In fact, it is somewhat of a mystery.
Within the Boot ROM is an array of functions that are linked through a jump table, indicating they are meant to be accessible across ROM revisions and thus intended for use by games. This is solid evidence that the calls can be freely used by developers if they wish. We do not have any official documentation on the Boot ROM library.
It is possible there never was such documentation to begin with, or was never translated to English. We have three different sources of Mega CD development reference manuals, most of which is wholly redundant, yet there is no sign of Boot ROM documentation. One of the later Technical Bulletins makes mention of these calls in passing, indicating that they may be used by games, so it wasn't secret information.
That same document mentions source code available on disks and via the Sega BBS which we do not have which may be the source of this information. In any case, there have been multiple attempts to reverse engineer the internal ROM and we now have a pretty good understanding of what sort of functions are provided. Megadev provides documentation, asm defines and C wrappers so you can take advantage of these tools in your code. A handful of games were entirely exclusive to the Sega CD such as Heart of the Alien and Snatcher and a number of Working Designs RPGs and as such these games are highly desirable and can be expensive to obtain.
A good portion of the Sega CD library also contains games based in part or in whole on Full Motion Video FMV which are live video clips that are used as the basis for the game play. Genesis 32X CD — A total of five games were made which exploited both the Sega CD and the 32X hardware since all three pieces of hardware are required to play these particular games.
All five games are FMV games. The games do provide modestly improved color and video resolution, but the video quality is still quite low.
So, instead of focusing on what games defined the Sega CD when it was on store shelves, we highlight games that motivate retro gamers to actually pick up a Sega CD in this modern era. It goes from the headphone jack on the Genesis to the Mixing input on the back of the CD.
With a Mk2, no mixing cable is required, just get the audio from the CD and the video from the Genesis. You could get something that would work at Radio Shack for a few bucks. The official Sega version has one of those noise reduder things molded into the cable, not sure how necessary it is. If so desired, all audio mono and video can be gotten out of the RF output on the Genesis.
When the 32X is involved, there are no additional connections concerning the SCD, but the connections between the Genesis and 32X get more complicated. See here for more detail and discussion.

These are the frames per second. That hides the annoying bars that display when playing a Sega CD game. When using Windows 10, upon attempting to enter fullscreen you may receive the following error message after an awkwardly long wait:.
Fortunately, there is a fix for this. Simply run Kega Fusion under Windows 7 emulation. Here's how:. Although Kega Fusion is a top emulator, the fact still remains that it hasn't been updated in a long time. When using Windows 8 or Windows 10, Kega Fusion may behave funny or even crash when you jump into full screen mode. You should be able to fix this by using the Windows Compatibility feature to have Kega Fusion emulated under an older version of Windows.
Here's how to set it up:. Save states is a feature that saves the exact spot you are in any game. You can use this feature manually by going into the File menu or by quick keyboard shortcuts. With them, you can continue at any significant point in the game. I offer a Game Saves Tutorial where you can learn more about how to use somebody else's saves. You can also learn about how to transfer saves between other emulators.
You need to make some small tweaks in the configuration before you start capturing screen shots. Want to upload your own gameplay videos to YouTube? Well Kega Fusion will let you capture them! Here's how you do it:. YouTube won't have a problem playing your video after you upload it. But, yet if you want to edit your AVI recording in a video editor, it might be rejected and not work.
A great, free video converter is Miro Video Converter. Finding cheats: GameGenie. The next best source is Google. Fast forward is the feature that speeds up the game. In my links page, I have some good links to sites where you can download ROMs. If you want to try to find more sites than what's in my collection of links, just Google around. Unfortunately, no. Genesis emulators, however, have not stuck to a similar standard.
At least, Kega Fusion isn't stingy with its saves as long as you keep using Kega Fusion. You can easily share your saves with other people who are using Kega Fusion. Or you can copy your saves for use on a Kega Fusion on another computer.
If you're using Kega Fusion for the first time and you're finding that you have all these problems:. Then your problem is that you currently have Kega Fusion in a read-only location on your computer.
You must move Kega Fusion to a more common location such as Documents , Downloads , or a folder on your desktop. Sega CD games existed on audio CDs.
