Hi folk!
I'd like to build my own cartridges using 27xxx eproms, anybody can help me with a simple schematic? thank you!!!

Check out the brief but very informative article by Scott Julian, named "How to make C64 cartridges". Not only does it contain a schematic, but also a lot of good information on how to create a cartridge. You can download the two pdf's here and here.

Thanks a lot. But is there a way to copy .d64 files in the cartridge? Or only CRT files will works?

The .d64 file is a complete copy of a normal C64/C128 disc, that's why it's called a disc image. The data from the disc has been dumped to the image-file. But not only the file data itself but also structural data from the disc, like sector information, disc header etc.

So a .d64 is not ideal to copy to an EPROM. However, there are programs to extract file data from a .d64. Or you can use for example the VICE emulator to load the file into emulator memory and then save it to your harddrive.

If you use the C128 emulator you have the BSAVE command which easily saves dumps from the emulator memory to harddrives.
