1 x Floppy changed see the tutorial
1 piece of universal card
1 part bar pin dual with 34 pins
Fine wire to the connectors or a piece of flatcabe

Start separating any one cartridge. I had a cartridge without label and used it as a basis.

Cut a piece of double bar. Mecca the part to be cut with his own cable. See the second picture. Just make a light force with a stylus that cut the plastic and the exact position.

Open the cartridge. This was already without central bolt, but has four slots that hold the two halves. I separated them with only a slight pressure of a small screwdriver.

step 6
I realized that it would be possible to place the plate pattern behind the plastic fitting, but this would need to cut the excess plastic.
Using the Dremel cutting tongue plastica. With a fine file, from the finish. See the second picture.
Repeat on the other slot.

step 7
Use the card terminal to measure. Make a small mark with estiliete to mark the cut. Start with the Dremel cutting and go slowly and giving finishing with a file.
Every few seconds to stop and test the size of the cut, for not overshooting.
Within minutes you will have to cut the right size.

See that the board should fit perfectly behind the slots.

step 9
Pra lid to close, and necessary also a small cut on each side, where the pins plastics enter the islands.
Corete slightly from the top to the bottom of the island, enough to pass the plate.
Finishing with a fine file. See the second picture.

step 11
Returning the card, see that the ROM is involved in a bubble of resin. How not an easy operation and withdrawal, let's just cut the connectors it.
I used a Dremel with a small cutter, but you can also cut with a knife. Make sure that separated the tracks. In doubt, test the tracks cut, lightly scraping the varnish to get contact.

step 12
Solder up the wires pin to pin following the pin connector C64. I seized the islands themselves crossing welding wires.
- Solder the D0 to D7 in CD7 to CD0 (pins 14 to 21)
- Solder the GND on any of the Brazilian version of the board (pins 1, 22, A or Z)
- Weld A0 to A12 CA0 ate CA12 (Y K-pin)
- No connector, solder / CS to GND
- Solder the / EXROM plate (pin 9) to GND. (This was connected to my board)
- Solder the / OE connector to / Romla plate (pin 11)
WARNING: The VCC, pin 34, is not bound!
WARNING: The image of the connector 34 and a top view of the connector.

step 13
And time to test. Attach the small plaque in the slot.
At first, you only fit the card, without the cable connected to the emulator.
Note that you must connect the plate with a resin ball facing up.
Call oC64 and it should start normally. If you give black screen or locks, turn off and double-check all the connectors.
After this first test, with the C64 off plug the cartridge to the emulator.
In the emulator, call holding one of the side buttons to enter configuration mode. Choose "Master System". Do not deceive me not! The C64 works with the same configuration of the Master.
Load a game originally IN CARTRIDGE 8kb. Note also that you need a rom file (. BIN or. ROM). Files. CRTs which are converted to cartridge emulators and images of the disk. D64,. T64 and others do not work!
