Sega Gopher (also known as Sega Genesis Arcade Ultimate Portable Player) is a portable version of the Sega Genesis manufactured by AtGames. Initially released in Taiwan in 2007, sales distribution of the portable console has since expanded to Europe and the United States as well. It was released in Russia as the Sega Gopher Wireless, bundled with FireJoy controllers, a set of wireless joysticks.
The memory card used by the console must have strictly 9 pins and sizes up to 8GB. FAT or FAT32 file system, SD, SDHC, MiniSD (adapter), MicroSD (adapter), MicroSDHC (adapter) memory cards are supported, the console may not read a memory card with FAT file system.
The USB adapter should not be included in the console if it is already connected to the TV. To do this, first, without turning off the console, remove the AV cable, turn on the charging and turn the AV cable back on. Otherwise, the charge burns.
Switching between TV and Portable modes occurs once when the console is turned on and when the MENU button is pressed (image output is reinitialized). The mode cannot be changed in real time.
In portable mode, the console operates at 60 Hz as Standard Sega Genesis.
In TV mode the console works at a frequency of 50 Hz, as in the European\Australian Sega Mega Drive.
Most games work correctly, and have been fixed to work on the console.[1]
There is no Mode button in console management. In portable mode, it is always pressed, so some games using the 6-button control do not work correctly. The whole fault is the architecture of the console because some tracks are used simultaneously for different signals. When the wireless joysticks are connected, the Mode button will no longer be pressed. This problem has been to manually correct[2] and add the button Mode.[clarification needed][3]
Processors in the console have different timings with the standard Sega Mega Drive and Sega Genesis. Namely, the main processor runs at a higher frequency, which affects some games in better performance, and the coprocessor at a lower frequency, which affects the worst sound quality and playback speed of audio samples.
Image in different game modes can be stretched. This is due to the fact that in portable mode, the console responds to the program that the video uses the NTSC signal, but actually uses the PAL signal, in this connection, in portable mode, the picture with a resolution of 320x224 stretched to 320x240. In TV mode, this is not observed, as the console to make full use PAL. However, in games with a picture with a resolution of 256x224, it will be stretched horizontally to 320 in both modes.
The sound is slightly understated by 4 semitones in the Yamaha 2612 and 7 semitones in the PSG. Also the DAC sound is a bit muffled and sounds in some games so quietly that it seems as if it is not at all.
Standard sound in Sega Gopher is stereo, but due to the negligence of the manufacturer outputs are mixed, and as a result, only mono is present. This problem could be corrected manually.[4]
Due to different processor frequencies, some games that use interrupts to transfer music data to the coprocessor memory may hang or have a distorted or missing sound.
There is a kind of console in black-and-black housing, where a set of built-in games, added the ability to adjust the backlight (4 brightness) and the ability to select a level in the built-in games of the first page, these settings will be saved in Serial EEPROM.
There is a possibility to add images to custom games menu select the game from the SD card using the program MDB_Edit,[5] or with a free analogue - ScreenGopher.[6]
If there are a large number of games on the map, having to scan them when turned on for the first time can be avoided. To do this, simply turn on the console and immediately press the menu button. However, this cannot be done if a new game has been downloaded or an old one has been deleted.
The console menu uses full-color mode. Unlike the standard (9-bit), it transmits the entire 24-bit color spectrum.
