官方懷舊機改機指南整理

從任天堂的Famicom Classic開始,敲響了這波懷舊風,各家主機大廠紛紛投入懷舊小機機的行列,這種用軟體模擬的機器,就像樹莓派一樣,都可以透過軟體方式進行破解,塞入ROM讓機器執行模擬器,甚至灌入不同模擬器讓小超任跑N64、小PS跑紅白機等玩法,以下收集一些改機指南站點,讓玩家有個方向可以依循:

[備份] 各主機Scart輸出RGB訊號腳位圖

這是從國外找來的資料,我覺得滿重要的,為避免來源網站突然消失,這邊做個備份,有需要還是請到原網站查看,點我前往

I found it on a forum and think it’s valuable data, just in case it disappear suddenly, I decided to make a copy, not to clone in purpose. If I violate your copyright please inform me and I will delete the post ASAP.

Sega Master System/Mega Drive

A/V output comes from an 8 pin female “U” DIN connector. Pinouts are: 1 audio, 2 ground, 3 composite video, 4 +5V DC, 5 green video, 6 red video, 7 composite sync, 8 blue video. RGB output circuit: Sony CXA1145 video encoder IC – outputs come straight from the chip.

Sega Mega Drive 2

A/V comes from a female 9 pin mini DIN connector. Signals are the same as the original Megadrive with the addition of stereo audio. Pinouts are: 1 blue video, 2 +5V DC, 3 green video, 4 composite video, 5 composite sync, 6 audio mono, 7 red video, 8 audio left, 9 audio right, and the metal shield is ground. RGB output circuit: CXA1145/CXA1645/KA2195/MB3514 video encoder IC – outputs come straight from the chip.

Sega Saturn

Connector is a 10 pin mini-DIN type. While it’s a standard connector, it’s extremely rare so don’t expect to be able to buy one from the local electronics shop (or anywhere for that matter). The Saturn puts out luma/chroma (s-video) as well as the usual RGB/CVBS. Pinouts: 1 composite sync, 2 audio right, 3 audio left, 4 +5V DC, 5 red video, 6 green video, 7 blue video, 8 composite video, 9 luminance, 10 chrominance. RGB output circuit: signal comes out a CXA1645 through a 75 ohm resistor and a coupling cap.

Sega Dreamcast

Utilises a proprietary connector for A/V out. Supports CVBS, RGB (TV), RGB (VGA, req. adapter) and luma/chroma. Pin 7 must be connected to ground to enable RGB. Pinouts: 1 ground, 2 audio right, 3 audio left, 4 +12V DC, 5 +5V DC, 6 RGB (VGA) select, 7 RGB (TV) select, 8 vertical sync (for VGA), 9 horizontal sync (for VGA), 10 composite sync, 11 chrominance, 12 luminance, 13 composite video, 14 blue video, 15 green video, 16 red video. RGB output circuit: proprietary DAC.

Super Nintendo

For some unknown reason the RGB output circuits differs between the NTSC and PAL consoles. As a result the cables are different too (though I somehow doubt Nintendo had any intention of releasing a SCART lead for the NTSC SNES).

Proprietary A/V connector. Pinouts: 1 red video, 2 green video, 3 +12V DC, 4 blue video, 5 ground, 6 ground, 7 luminance, 8 chrominance, 9 composite video, 10 +5V DC, 11 audio left, 12 audio right. RGB output circuit:
Pinout is the same as above with the exception of pin 3 which is composite sync instead of +12V. RGB output circuit:

Nintendo Gamecube

Nintendo are up to their old tricks again. The PAL console outputs RGB but not s-video and the NTSC model outputs s-video but not RGB. Therefore this cable will only work on a PAL Gamecube. However, it is possible to get RGB from an NTSC Gamecube by modifying the official component video cable. Here are some guides to the procedure:

MMMonkey’s NTSC Game Cube RGB Cable

Proprietary A/V connector. Pinouts: 1 red video (PAL only), 2 green video (PAL only), 3 +12V DC, 4 blue video (PAL only), 5 ground, 6 ground, 7 luminance (NTSC only), 8 chrominance (NTSC only), 9 composite video, 10 +5V DC, 11 audio left, 12 audio right. RGB output circuit: proprietary DAC.

Nintendo Wii

Like the Gamecube, RGB video is only available from the PAL Wii.

Proprietary A/V connector (different to the proprietary A/V socket used on previous nintendos). Pinouts: 1 left audio, 2 right audio, 3 composite video, 4 +5v DC, 5 ground, 6 ground, 7 red video (luminance/NTSC), 8 mode select, 9 green video (chrominance/NTSC), 10 mode select, 11 blue video, 12 ground, 13 +12v DC. Pins 14-16 are for something called a Japanese D-Terminal Cable. Mode select pins are normaly left unconnected. When they are connected together, component video (YUV/YPbPr) will output from pins 7, 9 and 11 in place for RGB/S-video. The DC voltage on pin 13 will drop to 5v for widescreen games (will it?).

Sony Playstation/Playstation 2

Propriety connector. Pin outputs: 1 ground, 2 audio left, 3 ground, 4 audio right, 5 luminance, 6 composite sync, 7 chrominance, 8 ground, 9 blue video, 10 +5V DC, 11 red video, 12 green video.
RGB output circuit: signal comes from a CXA1645 and a through a 75 ohm resistor.

SNK Neo Geo

Female 8 pin “C” DIN connector. Pinouts: 1 audio mono, 2 ground, 3 composite video, 4 +5V DC, 5 green video, 6 red video, 7 composite sync, 8 blue video. RGB output circuit: signal comes out a CXA1145/MB3514, through a 75 ohm resistor and a coupling cap.

Atari Jaguar

Propriety connector. Pinouts: 1A audio left, 2A audio ground, 3A n/c, 4A video ground, 5A blue video, 6A horizontal sync, 7A green video, 8A chrominance, 9A n/c, 10A INC (???), 11A unregulated DC voltage from power input, 12A n/c, 1B audio right, 2B audio ground, 3B video ground, 4B red video, 5B vertical sync, 6B n/c, 7B video ground, 8B luminance, 9B ground, 10B video ground, 11B composite video, 12B n/c.

Microsoft Xbox

Propriety connector. Pinouts: 1 audio right, 2 audio ground, 3 SP-DIF digital audio, 4 vertical sync?, 5/6/7/8 ground, 9 video output A (blue), 10 video ground, 11 video output B (green), 12 video ground, 13 +5v, 14 audio left, 15 audio ground, 16 horizontal sync?, 17/18/19 video mode select (ground all three for RGB), 20 +12v (RGB Status), 21 video ground, 22 video output C (red), 23 video ground, 24 video output D (composite video). Different audio/video configurations are selectable by maniplating the three video mode select pins (17, 18 and 19). See the Gamesx Xbox pinouts page for more info on this. The DC voltage on pin 20 will drop to +5v for widescreen mode.
