After discussion with several games authors, a decision has been made to support the NINTENDO MULTITAP (6 player adapter). This means a quality device will available to any IBM user wanting the multiple player option. The ciruits which accompanied the previous versions (EXT3,EXT6,INT6.GIF) have been withheld, for modification to suit the MULTITAP, and will be re-released with GAMEPAD PRO! V1.0. Expected release Mid-August. GAMEPAD PRO! V1.0 will also support SEGA and GRAVIS Gamepads. Circuit changes effect mutiplayer options ONLY. This shouldn't effect anyone as the multi-player SNES PRO! hasn't been released yet. Anyone who has already built one of the PASS-THROUGH adapters in the previous versions of SNES PRO! will only need to make small modifications in order to add MULTITAP adapter compatibility. Below are the basic circuits to connect an SNES Gamepad to your PC. ²f4 ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ³ Single Player Adapter. ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ ²f1 Description. The Single Player Adapter allows one SNES gamepad to be connected to a PC's parallel port. This adapter is the least expensive to buy or build. Our version has the appearance if a 'dongle'. Method. This adapter can be built by a) mounting the SNES pins on some 'veroboard' and soldering it to the DB-25 connector. b) Buying an SNES extension cable and using only one end of it, mounting the components in the DB-25 backshell. ²f0 PARALLEL GAMEPAD PORT (DB-25) 1 ÚÄÄÄÄ¿ Data3 ³ 05 ÃÄÄÄ>ÅÄÄ¿ | ³ | ÃÄÄÄÄ>ÅÄ´ ÚÄÄÄ¿ Data7 ³ 09 ÃÄÄÄ>ÅÄÄÁÄÄÄÄÄÄÄÄÄÄ´ 1 ³ +5Vcc Data0 ³ 02 ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´ 2 ³ Clk Data1 ³ 03 ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´ 3 ³ Reset Ack ³ 10 ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´ 4 ³ Data In 1 ³ ³ ³ 5 ³ Reserved ³ ³ ³ 6 ³ Reserved GND ³ 18 ÃÄÂÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´ 7 ³ GND | ³ | ÃÄ´ ÀÄÄÄÙ GND ³ 25 ÃÄÙ ÀÄÄÄÄÙ ²f4 ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ³ Power Adapter - Gameport ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ ²f1 Description. Two types of power adapter are available. This one and the keyboard version below. Both work well but this one is easier to build. Power is taken from pins 1 (5Vcc) and 5 (Gnd). Method. Connect a male and female DB15, back to back, and solder all connections. Solder the lead that has the 2.1mm Plug on it accross pins 1 and 5 of the DB15. ²f0 2.1mm DC Power Plug.

These can be any type (but preferably a Germanium Type). 2) or an external power cable 2) All Able Solutions adapters will have a 100 to x00 uf Electrolytic capacitor across pins 1 and 7 of the SNES connector. 3) SNES Connectors can be made from PCB pins, 1.2mm (diameter) by 10mm. Available in Australia from; Rod Ivrving Electronics A'beckett st Melbourne, 3001. Ph (03) 663 6151 4) Pin 1 of the Nintendo connector is the FLAT end. Pin 7 is the ROUND end. 5) When using an external adapter without a power source, problems may arise under the following conditions. ²f4 1) Using Infa Red (IR) type controllers. 2) Using certain Arcade type controllers. 3) Connecting too many hand controllers. NOTE: This would be rare if using the circuits above. I've tested most handheld controllers and have had any two working at the same time with no problems. ²f1 If any problems are experienced you can can bet it will be with a lack of power. This is because the standard IBM printer port does not have a dedicated power supply pin. As the circuit explains, power for the SNES Gamepads is taken from six of the data pins. Three problems may accompany this approach. ²f2 1) The output volatage of these data pins may not reach 5V. (Which is the standard supply from a SNES games console). 2) The diodes will drop an extra .2V (Germanium) or .6V (Silicon) off that total. 3) The current from these pins may not be enough, even after chaining five pins together. ²f1 While all this is starting to sound a bit disappointing, the good news is that the majority of gamepads use very low current (3 to 6 mA). Even better, the IC's (little black thingies) inside are CMOS and only require about 3V to work OK. So if your printer port only puts out 4V and you use a silicon diode, your still .4V ahead. Yes thats pushing your luck, BUT I haven't had problem running three regular handheld gamepads on the several printer cards that I've tried. My larger games console used a little more power than the handheld (only due to the LEDs) on the front but it still didn't present any problems. Also, the majority of users will only be using one gamepad. Many may use two (for fighting games etc.). So that will also be in your favour. Infared devices, those cordless jobs that work in a similar way to your video's remote control, may have a problem. I haven't tried one as yet but I expect that their power requirement will be 5V, more mA's and won't except any less. ALL THIS CAN BE SOLVED by building, or buying, one of the external power cables above. They simply plug into the gamepad adapter and source their power from 1) the GAME Port or 2) KEYBOARD connector. Initially, only the Single player adapter (with optional power cable) will be available from Able Solutions. I have the first version available as this software is released. It is a little primitive (not as professionally finished as I would have liked) but it is solid and will work forever. A decision has been made to support the SUPER NINTENDO MULTITAP device. It allows up to 6 players to be connected. This device is available as an accessory for the Super Nintendo (Famicom) Entertainment Console and is widely stocked in many stores where video games accessories are sold. NOTE it will require the optional power adapter. * * E N D O F F I L E * *
